Fruit Fly
Drosophila melanogaster
The tiny flies over a fruit bowl or a bar drip tray. They breed in a film of fermenting residue no thicker than a sheet of paper, which is why cleaning the visible surfaces never gets rid of them.
Where it lives
Fermenting fruit and vegetables, drink dispensers, beer lines, drip trays, mop heads, recycling bins, drains and the residue under bar equipment.
Signs
- Small flies hovering around fruit, bins, bars and drains
- Numbers building through the day in food and drink service areas
- Larvae in drip trays, drain slime or the base of recycling bins
Risks
- Transfers bacteria and yeasts from drains and waste to food and glassware
- Serious complaint source in bars, restaurants and hotels
- Contaminates open food, wine and fresh produce displays
Prevention
- Empty and wash drip trays and bottle bins daily
- Refrigerate ripe fruit and remove overripe produce
- Clean drains and the floor junction beneath bar units weekly
Treatment
We locate the breeding residue with a survey of drains, voids and equipment bases, apply a bio-enzyme drain treatment that digests the organic film, and support with targeted fogging and monitoring traps until the population collapses. In hospitality we also review cleaning schedules with the team, because sanitation is the permanent fix.
