Fruit flies are small, almost gnat-like flies that are attracted to rotting or fermenting fruit. These flies are about an eighth of an inch long, with small brown bodies, clear wings, and bright red eyes. Fruit flies lay their eggs on fermenting foods and moist organic materials, and the larvae will feed on these upon hatching.

Fruit flies can lay up to 500 eggs at one time. The eggs can take anywhere from one week to almost two months to hatch based on the surrounding temperature and the amount of fruit flies already in the location. The female will even put feces on the egg sacs to help establish the larvae develop! Once hatched, larvae take around 4 days to mature. Upon maturity, female fruit flies only need around 8 hours before becoming receptive to courting advances by males.

Controlling Fruit Flies

Restaurant kitchens, bars, and homes are the places we see the most when it comes to problems with fruit flies. These insects are typically found in kitchen or bathroom areas but can be found in other rooms as they will search out light sources at night. There is no specific time frame when fruit flies are most problematic and can be found at any time of year as long as their food source is present. We have multiple ways to control fruit flies, including traps and sprays. However, the best way to ensure full elimination of these flies is to locate and dispose of all potential breeding sites. If these sites are not removed, no matter how many sprays are done or traps are placed, the problem will still persist. Finding the problem can be difficult, but our technicians are here to help! Potential problem areas are locations where fruit is stored, garbage disposals, drains, cupboards, and even behind refrigerators.
