Fruit flies are the tiny tan flies hovering around ripening produce in Chicago kitchens, especially in summer. They breed in overripe fruit, fermenting liquid spills, drains, mop buckets, and recycling bins, and a small population becomes overwhelming in days because they complete their life cycle in just over a week.
What Do Fruit Flies Look Like?
Adult fruit flies are 1/8 inch long, tan to yellowish-brown, with distinctive bright red eyes and a humped back when viewed from the side. They fly slowly and hover above food sources.
Where Do Fruit Flies Hide?
Fruit flies breed wherever fermenting organic matter exists: overripe produce on counters, sticky residue inside recycling bins, the bottom of trash cans, fermenting beer or wine residue in empty bottles, mop heads, and slime inside kitchen drains.
Signs of a Fruit Fly Infestation
Small tan flies hovering above bowls of fruit, around trash cans, near sinks and drains, and in commercial kitchens. Adults are most visible at dusk under kitchen lights.
Health Risks of Fruit Flies
Fruit flies don't bite, but they walk on rotting organic matter and then on food prep surfaces — they can transmit bacteria including E. coli and Salmonella. In commercial kitchens they're a recurring health-code issue.
How Sleep Tight Treats Fruit Flies in Chicago
Sleep Tight treats fruit flies by identifying and eliminating the breeding source (this is 90% of the job), applying a bio-foam to drains where larvae develop, and using targeted residuals in cracks. Killing adult flies without removing the breeding site never works long-term.

Frequently Asked Questions
Where are the fruit flies coming from?
Almost always from an overripe piece of produce, a sticky recycling bin, or a kitchen drain with organic buildup. Find and eliminate the source and the problem ends quickly.
How fast do fruit flies multiply?
Extremely fast — a single female lays 500 eggs over her lifetime and the full life cycle completes in 8–10 days at room temperature.
Will apple cider vinegar traps solve the problem?
Traps catch some adults but don't address the breeding source. You'll keep seeing new flies until the source is found.
How long does treatment take?
Most Sleep Tight fruit fly jobs are resolved within 7–10 days once the breeding source is eliminated and drains are foamed.
