Exclusion & Sanitation
- Fruit flies typically hang around kitchens. The first step to get rid of fruit flies in the kitchen is to have proper sanitation. Sanitation is critical to eliminate any breeding sources.
- Clean garbage cans and dumpsters. They should have tight lids.
- Get rid of extra moisture on places such as floors with proper drainage.
- Use screens on building openings.
- Re-grout tiles in bathrooms and kitchens. Re-grouting prevents water leakage in the walls and reduces fruit fly breeding places.
Fruit Fly Inspection
Look for fruit fly breeding areas anywhere vegetables or fruits are
stored, unless refrigerated. Also look for fruit fly breeding areas in garbage cans, under appliances, and
recycling bins. When searching for fruit fly breeding sources, remember
that the larva can only survive in decaying organic matter that is moist.
All stages of a fruit fly infestations depend on organic debris to complete
the complete fruit fly cycle. Whenever possible, food and materials on which fruit
flies can lay their eggs must be removed.
Killing adult fruit flies will reduce the infestation, but
elimination of fruit fly breeding areas is necessary for good management.
Fruit Flies are not the only small fly that you may see in your kitchen area. If you see a small fly or gnat, it may be a drain fly or gnat. They are commonly confused with fruit flies. Fruit flies typically breed in overripe fruit, garbage, or other damp organic matter. Fruit Fly Traps typically only work against fruit flies so it is important to rule out other types such as drain flies, phorid flies, or Sphaerocerid flies.
Below is a list of possible breeding sources for various small flies found in kitchen areas and other breeding sites. If you understand the various breeding sources, you can manage these flies with better success.
Breeding Sites of Drain Flies, Fruit Flies, Phorid Flies and Sphaerocerid Flies
Fruit flies: You can find fruit flies flying around fruits and vegetables, both fresh and rotten. They can also be found around any moist organic matter and garbage.
Drain flies: Drain Flies are known to breed in sewers, drains, septic tanks, condensation traps, and contaminated soil from sewage.
Flies: Phorid Flies are also found in contaminated soils from garbage and drains.
Flies: These small flies breed in animal manure, garbage, and anything else wet and slimy.
Fruit Fly Traps
Fruit Fly Traps are the best on the market. It is a ready to use trap with a special attractant to lure the Fruit Flies into the trap and get caught.
Fruit Fly Control - Aerosols
Pyrethrin spray can be used as a quick kill, reducing
populations of flying insects. A pyrethrin space spray such as CB 80 Pyrethrin Aerosol, PT 565, or V-One Pyrethrin Aerosol. You can use pyrethrins in an automatic dispenser to be used with the the On Time Mist Flying Insect Killer. On Time Mist Automatic aerosol will last 30 days in the automatic aerosol dispenser.
Gentrol Aerosol is an IGR in a convenient aerosol can. An IGR (insect growth regulator) will prevent the complete fruit fly development. This aerosol can be sprayed around possible breeding sources such as, around plants, floor mats, under applicances and into drains to treat a broad range of small flies.
Drain Treatments - Get Rid Of Possible Sources
You may find fruit fly larvae feeding on the sides of your drains. In order to investigate this, put some clear tape over the top of a dry drain with some holes in it for air flow. If the flies get stuck on the tape, you have located a source.
Using a bleach is not effective. In order to break up organic build up and eliminate any possible breeding sources, use drain a treatment like Invade Bio Drain
Fruit Fly Control - Residual Insecticides
WP or D-Fense SC, are residual insecticide concentrates that yield several gallons of finished solution. Spray surfaces where fruit flies would land and rest, sprayed once a month. This would also treat other types of flies. Both products have a broad label for general pest control.
If you are looking for fogging insecticides and fogger equipment we have a wide assortment.
Fruit Fly Indentification
Fruit Fly Size (3mm)
Fruit flies are small about 1/8-inch in length including the wings.
- A key identifying character of a Fruit Fly is its bright red eyes.
- The Fruit fly is about one third the size of the filth or house fly.
- Body color is usually a light yellow to tan color.
Fruit Fly Biology and Habits
- Fruit flies comprise several different species belonging
to the genus Drosophila. The most common species encountered
in homes and other structures is the D.melanogaster. Fruit flies
are also identified as pomace flies or vinegar flies. These pests can
be found throughout the world, in homes, food processing plants, warehouses,
grocery stores, wineries, restaurants and other structures.
- Fruit Fly populations tend to be greatest in late summer and early fall as
they infest fruits during the harvest season.
- The fruit fly is among the smallest flies found in homes.
- With the end of the summer season, many homeowners often encounter
fruit flies in and about their kitchens and near garbage storage areas.
- Fruit flies are generally found hovering around decaying vegetation
and overripe fruit.
The fruit fly is most often found hovering around overly ripe fruit.
Fermenting materials, such as leftover beer or soft drinks, also are
a favorite food of fruit flies.
Fruit flies are often found in the kitchen, especially when vegetable
or fruit materials are present after major home canning efforts.
- Pomace Flies look like Fruit Flies and may infest homes. However, the breeding source may be something like a forgotten mop pail or open sewer drain.
- Because Fruit Flies frequent such unsanitary areas as garbage, it could potentially carry
disease-causing bacteria onto food products.
- Like all flies, the fruit fly develops by complete metamorphosis.
Eggs are laid near or on top of attractants (fermenting materials) such
as beverages, decaying fruit and vegetable matter, garbage or slime
The fruit fly is attracted to any area where moisture has accumulated
including mops and wet rags. The larvae emerge from the eggs and feed
near the surface of the fermenting material for 5-6 days.
- This surface-feeding characteristic of the fruit fly larvae is significant
in that damaged or over-ripened portions of fruits and vegetables can
be cut off without having to discard the remainder for fear of retaining
any developing larvae.
However eating the larvae can cause intestinal discomfort and diarrhea.
For this reason, health professionals and sanitarians are concerned
when fruit flies are found infesting facilities where food is prepared,
processed, or served.
- Newly-emerged fruit fly adults are attracted to lights, but egg laying
females will not leave fermenting materials. The fruit fly larvae then
crawl to drier areas of the food source or even out of the food source
to pupate. Under ideal conditions, the life cycle of the fruit fly,
from egg to adult can be completed in as little as eight days.
Life cycle from egg to adult is approximately 10 days.
