Bio Foam and NyGuard IGR, applied with a poly
foamer to all drains and fly breeding areas to eliminate scum, odors and
prevent growth of immature insect pests.
Fruit flies, gnats and other small nuisance flies are major pests of homes,
hospitals, restaurants, wineries and other businesses. These flying insect
pests generate more questions from our customers than most other pests.
Gnats and flies are a nuisance and are also a health concern for homes,
hospitals and any other business that deals with food, wine, beer,
animals. This article will deal with common problems that contribute to
fly infestations, non chemical methods to help control flies and general fly
Commercial kitchens, wineries or older homes that need on-going maintenance
should use Invade Bio Drain on a weekly or every other week schedule to keep
down odors and re-infestations. One application of Nyguard IGR should last
three to seven months. Most professionals use an IGR two to four times
Products Needed: Poly Foamer, Invade
Bio Foam and Nyguard.
There are several different types of products that can be used in fly
control but the use of these products is not always warranted. The simple
truth to controlling flies: Eliminate the source and you will eliminate the
problem. For medical professionals and managers of commercial food
handling establishments, eliminating all possible fly breeding sources can be a
major task. In many of these establishments the source (or sources) of fly
infestations will never be totally eliminated but diligent sanitation procedures
and constant inspection of the premises will be of great help in reducing
unhealthy, unsightly and generally annoying flies.
For those in charge of controlling flies and other flying insects or overall
pest control in the types of establishments listed here, sanitation is your
number one problem. Once you have control over sanitation problems you
will many times find that some sort of pest management program for flies must be
Getting control of all possible breeding sources is the first step in pest
management. This all important first step includes educating employees and
vendors. Once everyone involved has been educated and been given explicit
instructions, these instructions must be enforced or you will find yourself
spending entirely too much time and money on the problem.
Integrated pest management procedures (when strictly enforced) will limit fly
control products needed. Your goal should be to eliminate or control your
pest problem in the safest manner possible, using the least amount of pesticides
or eliminating the use of pesticides through the use of the best
fly traps and controlling hot spots such as drains or drain lines with
products designed to clear drains of fly infesting
Many fly traps are available for use in homes, restaurants, hospitals and
other establishments. In most cases flies are a problem in sensitive areas
where either food is being handled or where there are organic materials that
attract flies, gnats and ants. Hospital waste (a wide range of foods,
human wastes, contaminated bandages, unsanitary janitor closets, elevator
shafts, etc.) are usually taken care of in a professional manner but flies can
still persist even under the most sanitary conditions.
Fly sprays or any other type of insecticide should not be used in many
sensitive areas. In these sensitive areas that need to be pesticide free,
non-toxic traps are a must. Liquid traps are available but do not meet the
high standards called for in restaurants, hospitals and similar locations.
Disposable glue traps are the best way to capture flies, gnats and other
unwanted flying insects in sensitive areas. The number of flies, persistence
of the fly problem and areas where flies are to be controlled dictate which type
of trap should be used in any fly management program.
There are three basic types of glue traps used in flying insect control:
- Basic fly trap - The basic fly trap consists of a piece of thick paper,
ribbon or cardboard that is covered in a heat resistant, non-toxic
glue. These traps rely on perfect location to work. The theory
is that flies need to light or rest from time to time. When the flies
"light" on a sticky pad or glue trap, they cannot escape.
Since they lack a method of attracting flies, these plain sticky traps are
usually an eye sore (they must be placed in areas where they are obvious)
and are not as sanitary to use other traps.
Old fashioned fly ribbons are still in use today but are not allowed in
hospitals, commercial food handling areas or restaurants.
- Pheromone Fly Trap - There is not an attractant for fruit flies on the
Gold Stick; they will sometimes land on the trap while resting.
Pheromones used in fly traps excite flies and
actually draw them to the sticky capture pad portion of the trap. The Gold
Stick Fly Trap is an excellent example of a pheromone enhanced glue
In the past, fly ribbons relied on flies resting on their surface in order
to capture and kill annoying flies and gnats. With the addition of
special pheromones (which are not toxic or harmful to mammals when used
correctly) flies actually seek out the trap where they are captured and
- Professional Lighted Fly Trap
- Pest professionals have
long known that fly pheromones make fly traps more effective and they have
also known that certain ultraviolet rays (UV rays) attract many flying
insects. Professional lighted fly traps now use both attractants:
pheromones and safe ultraviolet light bulbs.
Matrix Fly Trap, Visu
Fly Trap and Ultralite
Trap are most popular.
Pheromones excite and
attract most filth flies. Ultraviolet light gives flying insects a
sense of path of least resistance. By combining ultraviolet light
bulbs and pheromone coated sticky pads, professional
lighted fly traps are now more powerful than ever and will attract
unwanted flying insects over a larger area. The more ultraviolet light
used, the larger area can be covered for safe fly control.
Professional lighted fly traps are not to be confused with bug zappers or
fly zappers. There are locations where fly zappers are preferred but
sensitive areas (restaurants, hospitals) or areas where the public can see
the traps should not use fly zappers.
Fly zappers or bug
zappers do create undesirable airborne insect body parts as the flying
insects are "zapped" and killed by an electronic grid.
Lighted fly traps that use pheromone coated capture pads are more desirable
and are safer to use in sensitive areas than electronic
ultraviolet fly zappers.
Home owners can choose between regular pheromone traps or lighted traps
that use both pheromones and ultraviolet to attract flies. Hospitals, restaurants
and other establishments that are sensitive (either by nature of their business
or need to look neat and clean to the public) prefer to use lighted
There are two basic designs to choose from when purchasing professional traps:
- Powerful Fly Traps - These ultraviolet light traps are designed purely
for power and are used in areas where ultimate fly control is necessary and
where the public cannot see the traps. The wide open design of these
particular traps can pull flies from quite a distance and cover large areas.
The Matrix II
Fly Trap is an example of a powerful lighted fly trap used to attract flies to a replaceable
glue pad. Captured flies and insects are visible with the most
powerful traps. Use a discreet style fly trap
in public areas.
- Discreet Fly Traps - A more discreet trap is called for when flies have
to be controlled in the public eye. Discreet fly traps can be placed
in public hallways, bathrooms and even on walls of a restaurant or in rooms
where surgical procedures are performed.
The Ultralite Trap is an efficient yet discreet lighted fly
Annoying gnats, fruit
flies, common house flies and other pests are captured on replaceable glue
capture pads. Captured flies and insects are not visible with the use
of discreet Ultralite Fly
Flies that breed in drains are often lumped into a single group called
"drain flies" although there are different species of flies that tend
to breed in the organic debris that builds up in drains. The Drain
Fly is another name used for the Moth Fly.
Other flies can breed in the same location. See drain
flies in the fly breeding
chart for more information.
Ridding a building of all possible sources in which flies breed will
eliminate fly populations in the building, unless the flying pests are
constantly being reintroduced into the building from outdoors. Fruit
flies, moth flies and other gnats
known as small flies need damp organic
material. It is in this material that they feed and lay their eggs.
Drains are notorious for collecting tiny particles that build up into a thin
organic film where gnats prefer to breed.
If drains are the source of your fly infestation you can use products to
eliminate the organic build up, treat with an insect growth
regulator (IGR) or use both - drain clean-up and
Invade Bio Foam is the best for eliminating organic film in
drains, cracks and crevices. The foam fills voids and covers all sides
with a microbial product that eats scum and organic material where flies and
other bugs breed. This organic build-up is also a major source of odors in
homes and commercial kitchens.
Drain Gel is a ready to use product.
Pour just a few ounces of Drain
Gel down each infested drain daily for a few days to rid the drain of fly
breeding material. Invade Bio Foam Concentrate
is a product that
is applied inside of drains to create a buildup killing foam. Invade
Bio Foam Concentrate can be used alone or mixed with an IGR for maggots.
NyGuard IGR and Gentrol
Concentrate are insect growth regulators that are active against fly larvae and other immature insects such as young
Another method of introducing an IGR in fly infested drains is with the use of Gentrol
Aerosol which is now labeled for use in drain lines.
When used as directed, the above products can be used without harming or
interfering with the action of septic tanks or sewer systems.
Wineries, restaurants, hospitals, pet grooming parlors and many other
businesses have a constant problem with small flies or gnats, due to the nature
of their business. Fruit flies, Phorid flies and other small flies that
most people generally refer to as gnats must have a source in which they breed
and feed. Without this primary source the fly population cannot
survive. Biting flies and fungus gnats are a little different from the
common "gnats" that invade homes and certain businesses. Biting
flies are not pests that breed indoors. If you need information about
horse flies or deer flies, go to the Biting Fly information page.
Fly Control Information
For other fly control problems, see the fly index.
Not all indoor fly problems have the same characteristics as problems caused by
flies living in drains. Cluster flies, fungus
gnats and biting flies are other types of fly
problems that are handled in a different manner.
Always do your best to eliminate any and all sources of materials that
attract flies and give flies a breeding ground and feeding source. If
these sources originate from drain lines, you may use Drain
Gel, Invade Bio Foam and Nyguard
products to cut down on the organic breeding material and make the materials
less likely to encourage the growth and development of fly larvae.
In situations where damp organic materials will always be available and
are next to impossible to control, the use of ultraviolet
lighted fly traps that use capture pads help keep fly populations
at manageable levels.
In some situations the use of pyrethrin aerosols can be used for a quick
knock-down of nuisance flies, gnats and flying insects. Either hand-held
aerosols or professional fogging machines can
be used to disperse safe levels of natural pyrethrins for killing flies and
other unwanted insects. Pyrethrins can be purchased not only in aerosol
form but also in a pyrethrin concentrate that allows
you to mix solutions for fogging or spraying.
