How to identify them

Fruit flies are small — about an eighth of an inch — tan to brownish, and many have distinctive red eyes. They hover and dart around fruit bowls, sinks, trash, and recycling, and their numbers can build with surprising speed.

Behavior and biology in South Florida

Fruit flies breed in moist, fermenting, sugary material: overripe produce, spilled juice or soda, the residue in recycling bins and trash cans, mop buckets, and the organic film inside drains. A female lays hundreds of eggs, and the entire cycle takes only about a week to ten days, so a single forgotten banana or dirty drain can seed a persistent problem.

Because the breeding sites are often hidden — a drain, the gap under an appliance, a recycling bin — the flies seem to reappear no matter how many are swatted.

Signs of an infestation

• Small flies hovering around fruit, sinks, trash, and recycling
• Activity concentrated near drains and under or behind appliances
• Numbers that rebound quickly after cleaning the obvious fruit
• Flies in bars, break rooms, and kitchens where sugary residue collects

Why they are a problem

Fruit flies move between decaying material and food surfaces and can carry bacteria and yeasts, making them a contamination concern in kitchens and food-service settings. They are also a stubborn nuisance, since killing adults does nothing about the eggs and larvae in the breeding source.

How Bugsy’s treats fruit flies

Elimination means finding and removing the breeding sources. Our technicians inspect for the hidden origins — drains, spills under equipment, recycling, and neglected produce — treat and clean the organic film where larvae develop, and knock down adults. Because a missed source restarts the cycle, we focus on the source, not just the swarm.

Preventing fruit flies

• Refrigerate or discard overripe and damaged produce
• Rinse recyclables and empty trash and recycling regularly
• Clean drains and remove the organic film where larvae breed
• Wipe up sugary and alcoholic spills promptly
• Keep mop buckets and cleaning tools dry between uses
