Flies That Infest Drains
One of the most common pest problems in homes, restaurants, hospitals,
schools and offices are flies that breed in or infest drains. In some
cases, correct identification of fly species involved can help to locate all
fly breeding sources and to choose correct methods of controlling the flying
pests. The flies or gnats (as they are sometimes called) are in a group we
call small flies.
Most people assume that the gnats seen in their home or business are Fruit
Flies but this is not always the case. Sphaerocerid Fly, Fruit
Fly and Moth Fly are the main culprits that infest and breed in drains. Sphaerocerid flies can be found in manure, damp organic material, drains,
rotting fruits and vegetables and garbage. Moth flies (also known as
the Drain Fly) breed in drains, sewers, septic tanks and soil that has been contaminated
with sewage. Phorid flies (often mistaken for fruit flies) are found in
sewage contaminated soil, garbage, drains, human cadavers, rotting vegetables
and fruit, garbage as well as damp organic materials. Fruit flies like
fresh fruits, rotting fruits and vegetables, drains, garbage and damp organic
materials. Another name for the Phorid fly is Humpback Fly. Its
hump-backed appearance is a key characteristic that helps to differentiate the
fly from the fruit fly. Phorids
also have brown eyes, instead of the obvious red color of the fruit fly's eyes.
To help identify your fly pest and/ or locate possible breeding grounds for the
pest, use the Fly Breeding Sites page.
As you can see, the most common breeding and
feeding materials are drains and damp, organic materials of some sort. One
of the most popular products to use for any type of fly that has invaded your
drain lines is Drain Gel. This liquid product is great for elimination and
prevention of these pests but a close inspection of the area should be made
before purchasing or using the product. Most people see small flies or
gnats in their kitchens and bathrooms and quickly assume that the flying pests
are emerging from their drains. This is not always the case! Drain
Gel is a great product but will be a waste of your time and money if the flies
are not breeding in the drains.
To find out if drains are actually your problem area or source of feeding and
breeding of small flies, use this simple test for your initial inspection:
Just before bedtime (or just prior to closing your restaurant or kitchen) you
should thoroughly dry off all bathtubs, sinks or areas around floor
drains. Your next step is to place a single strip of tape across the
center of each drain, sticky side of tape facing downwards. Do not
completely cover the drain opening! There must be open space to allow for
an updraft which allows the flies to emerge. Leave the strips of tape in
place overnight or (if possible) over a weekend.
If you find flies stuck to the tape, you now know for certain that that
particular drain does have flies. You can now proceed to elimination of
flies in your drain. If you do not find flies stuck to the tape, repeat
the tape test for at least 3 or 4 nights so that your test will coincide with
any possible breeding cycle.
This tape test is not complicated or expensive but it will help in determining a
possible breeding ground for your targeted pest. If you do not find flies
stuck to your tape (even after trying the test for several consecutive nights)
then you know that there are other possible breeding sources that must be
located and treated (or eliminated) in order to rid your home or business of
nuisance flies and gnats.
Locating materials that allow these pests to breed is one of the toughest
jobs in pest control. It would be simple if the fly infestations were
caused by an easily seen pile of garbage or rotting fruit but rarely is this the
case. The source is usually something small that has been over
looked. Repeated inspections over many days will eventually show you where
your problem lies. Many people get frustrated and purchase fly sprays to
knock down the flying pests but the flies always return - because the source has
not been located. A fly spray will give you temporary relief but the pests
will return. (Most of the flies killed by a space spray have laid hundreds
of eggs before you spray them!)
Once you have confirmed that drain lines are the source of your problems,
you can begin the process of removing the organic materials that cling to the
sides of drain lines. These materials can accumulate in any drain pipe and
rarely can they be removed with boiling water, standard drain cleaners, bleach,
Invade Bio Drain Gel is a product that was formulated specifically for the job
at hand: eliminating the material that is the source for flies, cockroaches and
ants and which also cause odors as the materials rot in your drain or sewage
lines. Invade Bio Drain Gel will not harm plumbing and is safe for both sewer and
The action of Drain Gel can be enhanced by using a foaming agent.
Invade Bio Foam is the same as drain gel but highly concentrated and developed
for use in foamer. (Invade Bio Foam
must be applied with a foamer.)
Fly Control in Kitchens, Restaurants
Many commercial food handling businesses such as restaurants, wine makers,
breweries and school cafeterias find themselves fighting fly problems long after
eliminating organic materials in drains. The reasons for continuous
problems can vary from type of business is being invaded to situations where
location of all possible sources is impossible. Any business that deals
with the manufacturing, packaging, storing or serving of wine, beer, sweets and
pastries or other such materials are likely to have continuous fly
problems. Unless a pre-planned pest management program is implemented the
problems are bound to get worse over time.
- Locate and eliminate all possible breeding and feeding sources for
flies and other pests.
- Instruct employees on all sanitation measures needed for your type of
business. The sanitation train begins with products delivered and
continues through food storage, preparation and disposal of waste materials
- all the way to the dumpster.
- Use certain products such as Drain Gel, Gentrol
and Stimukil or Maxforce
Fly Bait on a regular, preventative basis.
- Make good use of Ultraviolet
Traps to draw flying insects
away from your customers and away from foods.
When faced with such an on-going problems, other pest
control tools and methods must be used to keep unwanted populations in
check. Certain product can be used in drains as a preventative
- Drain Gel can be used once
each week to help keep organic deposits to a minimum. This will also
help eliminated many odors at their source.
- Gentrol products can also be used in a
kitchen. Gentrol Concentrate
and Gentrol Aerosol can now be used in
drains. The active ingredient in Gentrol products (Hydroprene)
is an IGR that helps prevent fly larvae (maggots) from
developing into mature adult flies.
Another IGR suitable for commercial food handling areas and inhibits the
growth and reproduction of flies, roaches and many other pests: NyGuard
The use of an IGR keeps flies from
reaching adulthood so that they will never reproduce. IGR also
works on German Cockroaches that can easily infest
a kitchen or restaurant.
- By using fly traps that use
ultraviolet rays to attract flies to their doom, you will greatly
decrease the number of flies in food preparation areas as well as in dining
areas. The most powerful of these traps are best used in kitchens or
food prep areas.
Matrix II Fly Trap and Visu Fly Trap are the most popular unit used in restaurant kitchens.
traps can be used in hallways, restrooms and even dining areas because
they have a low profile. A low profile fly trap is rarely noticed by
your customers. Even if your customers do see the trap, they usually
do not know what purpose it serves.
