Fruit flies are a small fly, about 1/8" long, that feed on the decaying, rotting or fermenting organic matter commonly associated with many types of fruits. But other such organic matter can lend itself to a fruit fly infestation as well. Fruit flies are common in home kitchens, supermarkets, restaurants, and other areas where organic food is in supply.
When considering treatment options for fruit flies, it is important to note that not all flies that look like fruit flies are actually fruit flies. Phorid flies and drain flies appear and behave very similarly, but require different treatment approaches to successfully eradicate. With fruit flies, the first consideration should be whether any decaying organic matter is readily detectable that might be easily removed from the environment. If there is a rotting bunch of bananas on the kitchen countertop smothered by fruit flies, for instance, an excellent obvious first step would be discarding the bananas (and removing them from the environment).
Sometimes the source of the fruit fly infestation is not readily apparent and further investigation is warranted. Improperly functioning garbage disposals have a tendency to allow a build-up of organic matter in the drain or pipes. (In general, flies coming from the drain are more likely to be phorid flies or drain flies than fruit flies). If this is the case, a drain cleaner such as Bio Draincan be used to break down the bacteria associated with decaying matter that enables fruit flies and phorid flies to flourish. (Flies not breeding within the drain won't be impacted by any sort of drain cleaner).
You may also need to consider whether produce has fallen in out of the way areas like behind ovens or trash receptacles. Removal of all decaying organic matter in combination with sanitation of floors, counters, walls, and trash receptacles, as well as use of an enzymatic drain cleaner generally provides resolution to fruit flies.
Fruit Fly Traps...
Fruit fly traps can be incorporated into a fruit fly mitigation program, but are unlikely to independently resolve the problem on their own. Without eliminating the source(s) of the problem, the fruit fly presence is almost certain to persist, at least until well after the organic matter has entirely decomposed. Considering using theInvite Fruit Fly Trap as a professional-grade fruit fly trap option.
Fruit Fly Insecticides...
Much like traps, fruit fly insecticides alone are unlikely to independently resolve the problem. Insecticide aerosol products such as CB-80 can provide immediate knockdown of advanced populations of live fruit flies in an environment. Before performing any pesticide applications, be sure to review all label requirements and state regulations.
