[Flies]
Hello.
Welcome to this training session
on fly control, fly service.
[Frank Meek]
Now houseflies are probably one of our major pest
that we have to work with around the world.
I don't care where you're at on this planet...
In every month of the year,
flies are active some place.
In some areas, they're active,
maybe 10 to 12 months out of the year the entire time.
But in others, they're very seasonal.
It doesn't matter where you're at though
houseflies and many of the other flies
are going to be one of the service issues
that we have to face.
So today, we're gonna talk
about some general control strategies
for these particular insects.
With us on the video today is Dr. Ron Harrison,
the other global Technical Director
for Orkin International.
[Ron Harrison]
So Ron and I are gonna walk you through fly service
and give you a little reminder
of some of those important things
about the flies, okay?
So let's jump in.
[The Enemy, House Fly, Blow Fly,
Stable Fly, Small Nuisance Flies, Many Others]
Now what flies are there out there?
There's thousands, tens of thousands
of different kinds of flies.
The ones that we are the most interested in though
are the houseflies...
Something commonly called a blowfly,
which also might be called a bottle fly
or a metallic fly.
So they're all the same thing.
But they're the ones that are drawn to dead animals,
decaying, rotting meat,
rodents or birds that we've killed
and controlled inside places.
Stable flies are another one
that are very common out there
that we find, you know, associated with animals,
associated with seashores, these sort of places.
Then there's this whole small group
of what we kind of refer to as a nuisance flies,
fruit flies, forward flies, moth flies, drain flies.
And as I said, there's many others.
But those are the ones
that we probably are going to face
and do face in the majority of our accounts everywhere.
Now, you know, flies are potentially dangerous.
We know that the fly is capable
of carrying and transmitting
over 100 different disease organisms.
Now think about this for a moment.
When we're out in public someplace,
we're out to eat, what have you...
We're in the little restaurant
grabbing a hamburger or something.
And we're sitting there at our table,
and a fly comes up and lands on our food
or on the table.
What do we all do?
What did most people in the world do?
Just sort of wave it away
and keep right on eating.
Not realizing how much danger that little insect is.
We say it's the second deadliest insect on the earth,
the mosquito being the first.
But the housefly can carry, like I said
over 100 different disease organisms very efficiently
and spread them around very easily.
So I don't think the fly gets as much respect
for the damage and the harm that it can do.
We know that regulatory bodies everywhere
are starting to look more at fly populations
as something that needs to be checked off
and points removed from health ratings
and things like that.
So it is becoming more and more important
for fly management.
And I think with that, Frank, what we're finding
is that communities are building
around animal facilities or around slaughterhouses
or even landfills,
which is causing the fly problem
to come more in contact
with where people live and eat.
So I think it's becoming, as I noticed,
traveling throughout the world a bigger problem
than even maybe a few years ago.
Absolutely. Absolutely.
Now this is not something new.
We've known for years that flies are a problem.
["The Fly Must be Exterminated
to Make the World Safe for Habitation"]
This is a newspaper
clipping from 1918 that says,
you know, "The fly must be exterminated
to make the world safe."
So, you know...
We've known about this problem for a long time
that flies are potentially dangerous.
And we have to work together with our clients,
and as Ron indicated,
sometimes, we have to work community wide
or in more areas than just our paying customers' site
to try to reduce this population.
So this is probably I think in my experience
and, Ron, you may have...
I think the same attitude or opinion.
This is one of our most difficult pest to treat
because of their great mobility.
And the fact that they're just everywhere
and can breed in almost anything.
Yeah, I agree.
I would say right now,
this is the number one pest that I face
in and out of wherever I travel.
Yeah.
So, you know, as I said,
there's a lot of different flies.
[Flies (Diptera) - Very Many Species]
So, you know, if you see here on this slide,
there's at least 120,000 different described species
of flies.
Now, you know,
we compare that to the number of mammals
that there are,
that's 22 times the number of mammals
that are on this Earth.
So, you know, these are massive biomasses in the world.
Things like the ants might be a larger biomass,
but this is pretty large.
This is a large, large body of insects
that are out there.
But there's only a small number of these
that we have to face and have to fight
and take care of our customers.
So let's just give you a quick reminder
of a little bit of the biology of these things.
And then we'll jump into the service and control
like information.
[Common Features - Development,
Complete Metamorphosis Egg Larva Pupa Adult]
Now...
Complete metamorphosis,
four stages, egg, larvae, pupa, and adult.
And true with most of the insects
and the fly is no exception.
The egg and the pupa,
we really cannot have control over,
we cannot kill the eggs,
we really cannot stop the female
from producing them.
We can remove maybe the source the place
where the female would prefer to put the eggs.
But there's really nothing
we can do to kill the eggs or the pupa
either one as far as that goes.
So the larvae and the adult are what we're focusing on.
And these animals in these stages,
they live in different places.
The food source for the larvae is much different
than the food source for the adult.
You were not gonna find the larvae and the adults
hanging out in the same place.
Typically,
we're not gonna find the pupa in the same place
as maybe where the larvae are eating, not always.
A few of the species we do,
but many of them,
that last stage of larvae will crawl away
from the wet area
to pupae to become a pupa and go on to its adulthood.
So often we're treating
in different locations
for these particular insects
and looking for different things,
adult versus young, the larvae.
And so an inspection process would be a big one
because we're inspecting different places as well.
Absolutely.
Now let's kind of look at some cool video
that our friends at Brandenburg provided for us.
[The female fly lays eggs on a suitable
breeding medium usually in batches of 100 to 200]
The female
produces these eggs one at a time,
and she can lay large numbers of them at once.
Depending on the species,
she may be able to produce 100 to 200 eggs
at one single time,
sitting on a surface someplace...
She's normally gonna try to find an area
where there's food resources for those young
when they come out of those eggs,
wet decaying organic materials,
garbage, dead animals, depending on the species.
So she's gonna find that
to produce and lay these eggs in.
Now when those eggs hatch,
they come out of this these little egg cases
as the larvae.
The common name for the larvae is the maggots.
So these maggots, these larvae,
crawl out of the egg cases...
Wiggle their way around and work their way out.
And then they just start eating,
they eat continuously almost
until they are going through
their entire growth cycle as a larvae.
They're gonna go through and molt...
Four or five times
on the way to becoming an adult.
That last moult is when they turn into the pupa
or become the pupa going into the adult stage.
So these things eat a lot.
So mother has to find a place
where there's food resources for them.
Without the food resources,
the larvae don't survive.
So when we think about attraction,
she has an attraction for her own food
but it's different from the food from her baby.
So when she's got eggs to lay,
like your picture was showing,
she's out hunting for very different odor
than the odor for her actually to get nutrients.
Exactly.
Now it's not uncommon to find
hundreds of these little larvae,
these maggots crawling over each other
and just devouring whatever food source is there.
We will often find...
Just massive amounts of them.
Rarely, at least in my experience,
do you see just the one maggot inside a place,
you're gonna see multiples inside there.
They're heavy eaters. They're eating all the time.
They just kind of scrape food into their mouth,
eat, eat, eat to give them the energy to grow,
molt, grow, molt on their way to adulthood.
Now the next stage moves
from the larvae to the pupa.
[Pupa]
And so that pupa is placed out there.
It's kind of soft and vulnerable.
After it's laid or becomes a pupa...
It then exposure to air,
it hardens and gets this hard pupa case
that protects that
developing insect inside.
Now this pupa is gonna be completely motionless.
It doesn't move very much at all.
Its movement may be caused by wind,
physical action by something else,
but it itself is not gonna crawl around or move.
When that larvae turns into the pupa...
It's typically there until it matures
into the adult and comes out.
Okay.
Now depending on weather conditions,
environmental conditions,
moisture, humidity levels,
temperature levels,
all those things determine how long it's going to take
for that pupa to go through complete
the maturity process to become an adult.
So there's not a...
You know, it's a question
we get asked all the time as well,
how long does it take to go from the egg to the adult?
And we typically talk about these things in ranges
14, 21 days for houseflies.
It can be much shorter
if the environmental conditions are perfect.
It can be a little bit longer
if the environmental conditions are challenging.
So it's all based on their environment.
Temperature and humidity
are the driving factors to their development.
Now when that pupa is going to become an adult,
this is something that's really unique,
I think to the fly world.
That adult when it generates inside there
or matures inside there,
it's got this little sack almost like a balloon
on the top of its head.
And it simply inhales and fills that sack.
And that pressure from that little airbag
on the top of its head
causes the pupa case to burst open.
And they work their way out of it
like you see here on the video
to emerge and become an adult.
When they make that emergence,
they're going to sit there
for a few minutes, maybe an hour,
depending on the temperatures
because the wings are soft,
they can't fly at this point.
Those wings have to have time
exposed to the air to harden up
and to be able to support that animal in flight.
The muscles are working, the muscles are fine,
but the wings themselves are too soft
to sustain flight at this point.
So when they first emerged,
as I said, they're gonna sit there,
let the air harden those wings up.
And then they can take off
and start searching for food for themselves first
and then mate.
Their only purpose is to mate
and keep the species regenerating.
So they're gonna find food
to replenish their bodies,
mate, and then start laying eggs
and recreating their species.
So the flies are out there...
They move around in great areas,
they can fly for good distances.
But being in the family or in the order of Diptera,
they only have two wings,
which means that they're not the greatest flyers
in the world.
So they can travel long distances in short hops.
So they may only fly a few meters,
100 meters, whatever the distance is.
If the wind is blowing good,
they can ride that wind
but they get tired.
So they've got to sit down and rest.
And that's one of the problems
is every time they sit down,
they potentially deposit some of these bacterium
that are on their body
and put it in places
or they pick it up from the surface
they landed on.
This is one of the ways that they're
such great vectors of disease organisms.
It's because of that flight
or the lack of flight ability.
They fly, but they don't fly great.
So they have to keep stopping along the way...
In order to get to their preferred area.
Okay.
[Common Features - Mouthparts Mostly Liquid Feeders
in the Adult Stage Often with specialized mouthparts]
Let's talk a little bit about
the mouthparts of these animals
because, yeah, this is kind of a unique thing
for this animal too.
These guys do not eat solids,
they do not eat solids,
they only consume liquids.
Now the maggots...
Okay, they do take in some solid food, yes.
But as an adult,
they can really only consume liquid foods.
But we see them hitting, you know, our dinner plate,
or that hamburger, or whatever,
that sugar grain that spilled on the floor,
that piece of candy, what have you.
Well, what they do is they regurgitate,
they vomit part of their stomach content
onto the surface,
which liquefies that surface
and turns that solid into a liquid,
they then can just simply take their mouthparts,
as you see here on the video,
which is like a sponge,
and absorb that liquid into their system to pick up.
Now one of the problems also is
everything they put out
is not necessarily taken back in.
So the saliva and vomit
that they put out on the surface,
they don't eat everything that it creates,
they don't take all that material back in,
so some of that is left on the surface as well.
So we get this potential bacteria transmission
from the animal's body
but then also from its biology of eating,
of creating food the way
that it has to go about doing that, right.
It's what makes them so dangerous.
Now for me, you know, as an entomologist,
I love these animals
because they're so interesting
to look at and to understand.
Their behavior is very different
from a lot of the insects that we work with...
Their ability to move around
and the way that they kind of make their own food.
They use ours,
but they have to make it so they can take it in, okay?
So controlling these insects are very important...
Because of the danger of the disease transmission.
So, Ron, let's...
Take us through some of the steps
and the approach to controlling these flies
'cause I know we get calls all the time
about I've got this big fly problem.
I've sprayed this, I've done this,
I've put up these light traps,
and I still got a problem.
So take us through some of the basic control steps
that we need to be thinking about.
Thanks, Frank.
You know, the fundamentals
of any good pest control program
is understanding the animal itself.
And so these morphological
and biological characteristics
that Frank talked about are essential.
[IPM in Fly Control]
That will help us lead
to actually identifying the fly properly.
And as Frank mentioned,
several different species that are out there,
we won't be able to control
unless we understand
which species it is and actually how it's behaving.
Frank talked about distances that they'll fly.
We know that blowflies can actually travel
or can detect a food source a mile away.
So that's 2 kilometers.
We know that houseflies are closer than that,
but even maybe 100 meters, 200 meters away,
they can smell that gas coming off of some type
of an organic material that they're attracted to.
So again, housefly IPM
or housefly control is always IPM,
integrated pest management.
And therefore, as we've talked about in our discussions
when you come to class,
there are four components of IPM.
[If I were a __? ___ fly, where would I want to be?]
Always, there is a biological component,
a cultural component, a physical component,
and a chemical component.
And so therefore, as we implement these components,
we wanna ask ourselves the question,
"If I were a fly, where would I want to be?"
Now go back to the specifics.
Which fly is it?
Frank articulated that if you're a blowfly,
you're dead or organic animals.
If you're a housefly,
it's gonna be more fecal material
or break it down organic materials.
If you're a fruit fly,
it's gonna be fermenting material.
So if I were a fruit fly, where would I be?
What would I like to be?
Now having said that then,
what are some of these common IPM practices
that we want to talk about?
[Common Locations]
So first of all...
Is there anything biological that can work for flies?
Well, flies attract organic material,
carrion on the slide, animal excrement.
So let's talk about that.
Now, Ron, so carrion is a word
that may not be common to a lot of people.
- Sure.
- Explain on that a little bit.
Dead animals. It can even dead carcasses.
We know that criminal investigators use entomologists
to go when there's a dead body,
there's been sitting there for a while
and analyze beetles and fly,
larvae, maggots, and adults.
So that helps with some of the species
in understanding.
So let's talk about our four components of IPM.
First of all, being biological.
Is there something biologically
we can use to control?
Well, there is.
In the United States and throughout the world,
one of the largest horse races
is called the Kentucky Derby,
which is held in Louisville, Kentucky.
And this race brings horses throughout the world.
They have stables of hundreds of horses
that are on site,
and we take care of that problem.
Well, there are small little parasitic wasps
that go after the larvae and pupae of houseflies.
So we release them
to help reduce populations in manure pits.
There are some soldier flies,
they do the same thing.
Point is always is there something natural
that I can implement
that will be helpful,
doesn't work with all, I know
that chickens like to eat cockroaches,
and you wouldn't wanna release
any chickens inside of a restaurant.
But on the other hand,
you certainly could use some types
of parasitic wasps and other flies,
so other flies to help dominate.
But then that leads us
to the other three components of good IPM.
What can we do culturally to help?
And Frank alluded, and I love that slide.
If you've got dead animals,
if you have fecal material,
if you have organic material,
all of those need to be addressed.
As long with their food source,
if you've got garbage cans that you're not replacing,
meaning the food or debris in the garbage cans,
that's a problem.
If you don't have lids on top of the garbage can,
if you have big dumpsters
that are full of gook running down the sides,
that's a problem because, those are odors
which are going to attract the fly
either to deposit eggs or for food for itself.
So any type of cultural control is essential
[IPM]
to be able to help with the...
And so that's habitat modification,
which is actually on this slide right there.
Another point about habitat modification
would be physical control.
Not long ago, I was visiting a customer,
and they were complaining about flies
in the hospital rooms.
Well, the weather was always nice outside.
And so people had windows open,
the patients had windows open.
And unfortunately, there weren't screens.
How many times is a door open?
Another location, where the employees come and go,
and they said, "Well, we leave the doors open
because there's so many employees."
Well, when you have a door open,
that is a habitat modification,
that's a physical thing that we need to do
or you can talk about cultural,
they kind of fit together,
that makes a big impact.
Here's an example when you have
these type of conditions that are on the slide.
You're going to have flies that are attracted,
probably for two reasons, one for them for food to eat.
The other one is for them to lay eggs
on those decaying materials.
Cultural control,
helping customers realize
the severity of it is essential.
Now physical control
ties a little bit into the garbage as well
but how can I physically keep that fly
from coming inside?
Not long ago, I was actually
in a big mall in the Middle East.
And flies were in the center of the mall
in the grocery store there.
Boy, that seems like a long distance
from doors to get in?
Well, when I talked to the mall facilitation,
they said, "Well, the weather is so nice,
we're turning off the air conditioning."
So what does that do?
A door opens up.
And rather than having air pushing out
of that door, there was no air at all.
In fact, it was kind of being sucked in.
And then as I watched the doors,
security guards like to have some dogs there with them.
Particularly they were kind of stray dogs,
but still they were feeding them,
they were defecating, urinating there.
So you have an attraction at the door,
doors opened up,
and now you had actually a negative air pressure,
which was sucking the air in.
Physical control is physically
then whether it's air curtains,
whether it's pressure of a building,
or whether it's actually a flylight
that's catching them, or a door sweep,
or there's something around
actually some type of penetration.
Those are all physical methods.
Now, Frank, a lot of times
we jump quickly into these physical methods,
and particularly flylights, we say,
"Okay, I got flies inside.
Can you give me some ideas
on how we should properly use
the physical IPM method...
A physical method to catch flies with the flylight?"
So, you know, I think one of the problems
that I hear quite often is,
you know, the client will say,
"Well, I want fly control,
I've got six of those flycatchers on the wall,
give me 10 more because those six
are not keeping the population down."
So in our clients' minds quite often more is better.
Give me more, give me more,
put those lights up.
Don't talk to me about cleaning
and things like that,
just hang up those lights
and that'll control my fly population.
And we know that's just not,
that's not gonna cut it,
that's not going to do the job by itself.
ILTs, insect light traps
were really designed not to be control devices.
They were designed to be monitors of the sanitation.
By that, we mean this.
If we observe that we look at that flycatcher,
and we say, okay,
what's captured in this trap
or on this glue board is a housefly.
That means, there's a source
of decaying garbage or feces
or something like that in the area
that brought that fly here.
Where is it?
So we kind of say,
it's a monitor of our sanitation conditions.
Ron mentioned the fruit flies earlier.
Fruit flies are not really attracted to light,
but just for a few hours
after they emerged from the pupa case,
that adult will go to light, into light traps.
But after she's been out for a day,
she has no interest in the light.
She's looking for someplace to lay her eggs.
So if we find one inside a light though
we know that we're looking
for some decaying organic materials
that are fermenting, breaking down.
So these are our monitors of sanitation,
not control devices.
Now I don't want to discourage us from selling them
because, you know, customers want them.
And part of our job is to satisfy the client
and make sure that we're taking care of them
and controlling their problems.
But we need to be careful
about overselling flytraps to someone.
I don't care how many traps you have in there.
If you don't have the sanitation
to go with fly service,
flycatchers are not gonna solve the problem long term,
they're gonna still be there.
They're still gonna be there.
I know I've been into marketplaces around the world
and you walk into the grocery market,
and there's 20 flycatchers
hanging in the produce department.
And the store's complaining about flies still.
"Maybe I need 10 more."
"No, you don't."
Why don't we focus on figuring out
where they're breeding at
and control that, take that away?
Or like Ron said,
do we need to do something
to the doors or the vent openings,
or something to stop them from coming in
in the first place?
Now we do use flycatchers,
we use them a good bit.
And so let's look at a little bit
about placing those things properly.
[ILT Placement]
And then we'll get into the chemical components
of things in just a little bit.
Now we know that the ideal height...
For these devices is about 2 meters off of the floor.
Why?
Because when a fly is questing for food,
they're typically flying between
that one and 2-meter height...
To find food.
So if we've got this light trap in that range,
they're more apt to find it.
I would say the lower side
rather than the higher side of that
'cause I see some 6, 8, 10 feet high.
Exactly.
Get it closer to that...
- That 1 meter.
- One me...
Excuse me, meter, I meant 1, 2, 3-meter high
closer to that 1 meter.
Yeah, absolutely
'cause, you know, they like the warmth.
So as the day progresses
and the building heats up, heat rises,
so through the day, our temperatures
go from cool down here, get warmer.
And then just gradually warm upwards
through the building
because, like I said, heat rises up,
that's a matter of physics, we can't change that.
So those flies as the day progresses
are gonna move up.
So if we wanna capture them as much as possible,
while people are there, in the daytime,
they need to be a little bit lower
into that 1, 1.5 meter range
as opposed to the 2 or 3-meter range.
Now there are situations
that maybe we need to have them at different heights...
Daytime, and maybe a nighttime device,
so that when they're moving up
to catch that last little bit of warmth
before they sit still for the evening...
They have an opportunity to find it.
The light to the fly...
Equates to the outdoors.
I can get outside where I know it's warm
because the sun is shining on me.
So as they're moving up trying to find that warmth,
you know, maybe we need to consider sometimes
having them at two different heights inside a place,
it might affect our captures a little bit more.
Maybe they need to be on a different times.
The one that's at 2 meters,
maybe it doesn't need to be on
in the middle of the day,
maybe that one needs to come on closer to,
you know, mid afternoon
as the fly start moving.
So, you know, there's a lot of variables
that we have to think about
in putting these devices out there.
One of the problems
they have are the customers themselves.
The facilities, we have to put them in,
you know, we say we want to put them
in that 1 meter to 2-meter range,
well, how many places do we go into
where there's an open spot on the wall...
In that height range
near an electrical source...
To put this device.
You know, a lot of times
the environment that we're happening to put it in
will unfortunately dictate where it goes.
And it may not always go
in the optimal place.
That's the other reason
why we cannot depend on them to be control devices.
We can't always get them
where they really need to be at.
Okay.
Now there's a lot of different types
of traps out there.
[Insect Light Traps - How do they Work?]
They're the insect light traps,
the ILTs, they use ultraviolet light to capture flies.
We know from studies done years ago in the UK
that there's a very specific range of ultraviolet light
that these insects are attracted to.
[The Electromagnetic Spectrum]
The graph here shows kind of what ultraviolet light is,
the spectrum is a very narrow range.
So these traps give off this specific range of light,
this specific spectrum of light
that is attractive to the fly.
And by attractive, we don't mean
that they're going to come in
and see that and magically run into it,
we mean that it's something they can see.
You know, just like we cannot see
that light spectrum that they can,
they cannot see the light spectrum that we do,
not in the same way.
So that range of light,
which is very, very small
is extremely important to the fly.
Now that means that the tubes
inside those devices have to be kept fresh.
We know that most of them
depending on the model and the type,
they're not gonna last forever,
most of them have to be changed out
at least once a year.
And some of the lower cost units,
you may have to change out
two, three, four times a year.
Just if the better quality the unit is,
the longer we can leave those tubes in.
The best ones on the market,
however, we're still not gonna leave those tubes
in more than a year.
Let me comment on that just for a moment, Frank,
because I think sometimes
we say a flylight is a flylight.
We say the same thing, a glue board is a glue board.
And there's a lot of science that goes into
those.
So when you say,
"Well, there's another one on the market,
it's the half the price,
I think I'm gonna go for that."
Boy, there's a lot of things
we'd like to talk to you about
the angling of actually the metal
that usually is what they're made off,
that will help direct,
that will increase sometimes
the reflection that's bringing them in,
the positioning, whether it's on the wall,
whether it's laying flat.
So I was recently in an account
where there were no flies on the flylight
with the glue board behind the flylight,
but there were lots of flies.
Point is the lamp was an old lamp,
and it wasn't even the right type of UV
that was needed out of it.
So be very cautious about getting a cheap
lamp,
a cheap ILT,
it may not be providing what you need.
Now I believe I'm a scientist,
I don't believe I am.
So the point is you can try a couple of them to see
what the percent of catches are.
But I've noticed that if you want better fly control,
you replace your lamps every six months
rather than a year
because they're certainly going down.
And the flylight, the design of it,
we see some very fancy ones
that can go out in the restaurant area
but they're not very effective in catching flies.
So you might have a fancy light,
it looks good but isn't really effective.
Exactly.
Now we kind of mentioned what they see.
So I wanna give you just
a little illustration of that if we can.
So what does a fly see?
So I'm not there yet.
[What Does a Fly See?]
Do it again.
So we talked about what the fly see.
So let's see kind of an example of that.
So I have a little illustration here
that I want you to look at.
What does a fly see?
Well, when we hang in a light,
that's what we would see is this,
the light hanging there.
What does the fly see if this is done correctly,
they see this.
The brighter, that bright yellow and reds
in the middle are the heat sources.
That's what the fly is seeing is that brightness.
So when we say they quake these traps to the outdoors,
it's a means of escape.
You know, I don't think these insects
really want to be inside any more
than we want them inside.
They'd really rather be out there
where there's a lot of food
unless they're in the supermarket.
But in the supermarket,
the temperatures are a little cool.
At least in the ones I've shopped in,
you know, they're a little bit cooler
to protect the integrity of the product inside.
So yeah, maybe
that's not exactly the environment
they really want to be in
from a temperature standpoint.
Okay.
[Important Considerations]
So some important considerations about these,
the response to the light,
it varies depending on the different species of flies.
They're really not gonna see
these things more than about 30 meters.
We get outside of 30 meters,
we're not really attracting any of them.
We know that it's best
if they're in 15 meters or less of the entry points.
So that's why we tend to try to get them close
to doorways in darker areas
'cause the idea is we want that trap
to capture that fly
within minutes of it coming in.
If it's in there for an hour flying around,
it's already deposited the bacteria,
it's already potentially laid eggs.
So, you know...
The response we want is really, really close,
3 to 4 meters of a doorway if possible
because that's gonna be our first chance
to prevent this problem from happening in there, okay?
So, you know,
just be careful in depending on these devices,
they're not 100%,
they're not designed to control.
- Frank, can I just jump in for a...
- Yes.
Quick point. Absolutely.
So there are three or four things to pay attention to.
Number one,
even though it's only 300 meters,
excuse me, 30 meters or so they're going to attract,
you still don't want them to be seen from the outside.
Sometimes, I see them placed right by windows.
And so a fly can be saying,
"Hey, well, maybe that's my escape route."
So position them,
so they're not...
A fly can't see from the outside.
Position them so the first thing
that the fly sees is your flylight
if it comes in a door.
We don't want to attract it in
but if it comes into being blown in
or comes in from some other reason,
we catch it.
Also highly placed flylights
are not as good as getting them down
to that 1 to 2-meter range is pretty important.
And a fourth concept that I like to think through,
they all most of them work by plugging them in.
And I have seen people say, well,
this is the perfect location
but there's not a plug in there.
So if you can't have an outlet placed there properly,
then you're gonna have to adjust that.
So analyze a flylight on itself is not gonna work
unless it's been put in the proper locations.
And those are four things
that I like to pay attention to.
You know, Ron, there's a lot
of different types of flylights.
We have, you know, ILTs, the insect light traps,
which use glue
and ultraviolet light to bring them in.
We also have the electrocutor,
the older ones,
the electrocution devices that a lot of people like
because they're less expensive.
The service,
you know, fees or charges that most pest controllers
use for these devices
are a lot lower for the electrocutors.
They're cheaper units as far
as price of the actual device themselves.
So let's go through and talk
about those things a little bit.
What are the different types of lights
that are out there?
[Types of Insect Light Traps]
Yeah, Frank. Thank you.
So these electrocutors...
And sometimes, grocery stores
or other chains will require so many of those.
I would again recommend or encourage us to say,
"Are you placing them in spots that may attract?"
I know in some grocery stores,
flies are becoming a bigger problem
because they have those on.
Second of all, Frank,
it's very interesting the way they work.
An insect light trap catches it into glue board,
usually behind the light or underneath the light,
somehow it's positioned,
so when the flight comes in, it gets caught.
That's not how it works with the electrocutors.
The fly is attracted by the light, and it explodes.
And I think there might be even a picture
or a slide of that where...
[What Happens to the Fly? High Voltage Traps]
Now so what happens is when it gets exploded,
yes, fly parts will go in a variety of directions.
But, Frank, it has been articulated very well
that there's all these bacteria
on side of the fly.
So you're sharing those all over.
So think about that.
You put one of these above the deli.
Flies come, they get attracted and explode out,
and now you have got meat and cheeses and vegetables
that are being covered with not only insect parts
but also the bacteria that's associated with them.
So, yes, there are locations
that are appropriate,
but I don't want to buy the sandwich
and have a head of a fly let alone all that bacteria
that's associated with it.
So positioning of these electrocutors
versus the positioning of the actual trap,
which is the glue board and catches it,
doesn't explode.
It's very important.
Okay.
So, you know,
we've said before also that it's not just traps,
we've got to also combine this with cultural changes,
the only permanent control for any fly population.
It doesn't matter which species of fly it is,
the only permanent solution is proper sanitation.
Reduce the attraction,
reduce the ability for this insect
to breed to lay eggs,
to procreate the species.
Sanitation is critical.
It's one of the things that we have to work
with our clients to maintain.
Now not all sanitation problems
will become fly related.
Garbage that is, you know,
dry paper, cardboard boxes,
these sort of things, those are really
not necessarily fly attractants
as they are attractants
for cockroaches or rodents.
So not all sanitation problems
are directly related to flies,
but all flies are directly related
to a sanitation problem.
So always remember that we got
to be taking care of the sanitation,
helping our customers identify
where their problems are
and then offering them recommendations
on how to fix it.
Our job is to assist our customers
in those recommendations.
Now, you know,
one of the things Ron and I've talked about,
I know with a lot of you out there is,
you know,
if we have an ongoing sanitation problem
and our service is not performing the desired effects,
controlling flies...
If we just keep spraying chemical
or depending on traps and changing glue boards,
we're spending a lot of time and money
on items that are not working.
Why not just clean it?
If it's a small thing,
you know, part of our service could be,
"Well, I've got this little small area of refuse
that needs to go away,
why don't I just bag it up and take it away?"
That is flight control.
And maybe we need to consider
some of those types of actions
in some of our accounts.
I'm not suggesting
that we become a cleaning companies
and go out there and scrub a kitchen floor.
That needs to be the responsibility of the client.
But sometimes, it's just a small little thing
and that small little thing will make a big difference.
So, you know, don't always reach
for the can of spray
or sell them a flytrap,
maybe sometimes, we just need to do
a little cleaning ourselves,
instead of bringing it to the customers attention,
just bring it to their attention and then do it.
If it means results
that the customer likes, why not.
At the end of the day,
we're controlling the pest,
and I don't think anyone's complete
job description is spraying chemical,
it's controlling the pest.
Absolutely.
Now talk to...
You mentioned chemicals.
[Chemical Applications]
Yeah, you bet.
But that is part of the service.
We've got to use chemical still sometimes,
most of the time I would say.
We're gonna use chemicals with traps, with sanitation.
- That's right.
- So take us through with that.
Idea means a variety of methods.
And so there are some residual products
and non-residual.
So let me chat with you just a little bit about those.
Something that has revolutionized
the treatment of flies are baits.
Frank, you know,
way back about 20, 25 years ago,
cockroach baits were developed.
Well, now we have...
Where in last 10 years,
I guess, maybe a little longer,
but we have very good fly baits
and that has changed things the way
that we think about.
These are products that can be used inside
as kind of a liquid that you spray in locations,
they can be used outside in granular
or actually painted on surfaces.
But usually they are more highly attractive
than even some of the natural foods
that they like to feed on.
I have used them at fish fries outside,
where, you know, fish are just such an attracted,
and I put my baits,
maybe 20, 30 feet away
from where they're cooking or where serving
and the flies go over there.
You'll need to decide which fly bait
is available in your market.
Do you want to use it
in a granular form or a liquid form
or a painted on form that you dissolve?
But the point is these are great methods
that give you long-term residual control of flies.
Now, Ron, let me jump in a little bit
about some of the baits
'cause, you know, Orkin has been involved
with the manufacturers
in developing these things over the years.
And just a word of caution,
you know, Ron mentioned the fish fry,
that's a very odorous area.
So what makes them go to something else?
An odor that they like more.
And so some of these products
as good as they are,
you got to be careful where you use some of them
because the odor would be offensive to the people.
Very good point. Yep. No, I think you're right.
And also there's a variety of baits out there, Frank.
Some are more odors than others
and they may not be as attractive.
I've worked in...
I've had three of them sitting there
inside of an office.
And all the flies only went to one,
and I thought that doesn't seem
to work over in this location.
So test them, try them,
check the odor of them.
I agree, I have been, whoa, that stinks
and that would not be appropriate for food location.
We have liquid products that we can apply.
And think about these sometimes as repellents
or pyrethroids are quite good repellents.
On the other hand, sometimes, they're formulated
in a wettable powder that when the flies,
Frank said, they will land on surfaces
if we can put some type of product that kills them
if they land there.
I've used these on dumpsters and other things
where you have a residual product that sticks there,
the fly doesn't know it sometimes
isn't really repelled by it.
And so therefore,
it will be able to die right there on the spot.
So you're looking from an external standpoint,
most of the time to try and keep those flies
from coming inside.
Now we also have some kind of friendly products,
some insect growth regulators,
they've been very effective
for some of the flies that are inside breeding.
Your houseflies that are breeding outside
not so good,
but for a fruit fly or a phorid fly
that concentration of IGR can build up,
it can be
very, very effective.
Now remember, these are residual products,
whether it's a bait,
whether it's an aerosol, whether it's a liquid,
all of these, whether it's even an IGR,
they stick in place and they help.
If you have an emergency,
and I was recently in a grocery store
in one of our foreign countries
and the flies were so bad.
I said, "We just got to get
that population down inside."
People won't even shop here.
So then we go with our fogging type,
which is our last point there,
but again, that's a non-residual.
And if the flies keep coming, and to Frank's point...
If you're not stopping them,
then you may end up having to do daily
to keep these fly populations down.
So fogging definitely could be something
of a last resort in an emergency,
but most of the time
you want to do those other chemical things
that will have longer lasting that are more effective.
Yeah, you know, and that's a little sensitive too
because a lot of customers demand that
fog, fog, and not understanding,
you know, some of the dangers of doing that.
You have not only the contamination potential
of what's there,
but you know, with flies we know
that we can develop tolerance levels
and resistance levels very quickly
by continuous use of fogging
these non-residual products
and continuous use
of some of the residuals on surfaces.
We know that that can develop
in a relatively short period of time.
So we want to try not to depend on chemicals totally.
It's part of a system.
It's part of an approach,
an integrated approach to flight management.
It's one component,
it's not the component.
- Do you agree? Yeah.
- No question.
We can't rely on, and flies
have become highly resistant.
So some of our chemistry that we're using, Frank,
so, yes, without a doubt.
On the other hand,
IPM doesn't mean no chemicals,
it means, using them judiciously.
And I would without a doubt
put all of your tools out there
so that the customer is not harassed by flies.
So on Scout, again,
you have the fly control manual
that Orkin has developed for you to use.
And in that manual,
that breaks down a lot of the biology
and the habits to help us understand.
I have this specie of fly,
this is where it wants to be at.
This is the habits that it likes and is looking for.
And it goes into more detail on placement of chemicals,
placements of the bait products.
So, you know,
please look for the fly manual on Scout
and also in your franchise material
that you have there in your operations.
As also, you can contact and a lot of you do,
so please continue that.
Contact Ron or myself
or any member of the staff
to ask questions and get ideas
on fly management
in specific situations that you have.
I know Ron and I both have been involved in situations
that were pretty simple...
Where just a little cleaning
and maybe repairing some doors or screens
solve the problem.
But then we also have been in those
that are much more complex,
where we have prevailing winds bringing insects
into an area that they don't normally want
to be at and causing problems.
So we have to get into analyzing
the entire environment outdoors
to figure out how to stop them,
so these can be relatively simple.
Most of them I think can be
relatively complicated and difficult.
So you run across the situation
that you're struggling with,
please shoot us a line on email...
Give us a call on our phones,
and we'll help you through those.
Look for the information on Scout,
and your training materials,
and then also in the technical manuals
for more information and details on that.
So, you know,
thank you for watching this video.
And, you know,
call us with your questions, call us with your problems
when you have them.
And best of luck to you all.
- Thank you so much.
- Yeah.
