How to get rid of fruit flies
A practical guide for kitchens, pubs and commercial food businesses across Hertfordshire — from fast DIY fixes to professional treatments that stop infestations for good.
Why fruit flies are a problem
Rapid breeding
A single female can lay 500 eggs in her lifetime. Under warm conditions the whole cycle from egg to adult takes just 8–10 days.
Food contamination
Fruit flies land on waste and decaying matter before walking across food-prep surfaces, bins and open food — a genuine hygiene risk.
EHO & audit risk
For pubs, restaurants and food manufacturers, fruit flies are a common reason for environmental health inspection notes and audit failures.
The three-step fix
Find the source
Fruit flies breed in tiny amounts of residue. Check bins, recycling, drains, beer lines, fruit bowls and under appliances.
Set traps & clean
Vinegar traps catch adults. Scrub drains with enzyme cleaner and wipe every surface where organic matter builds up.
Proof & prevent
Seal bins, fit drain covers, clean beer-line traps and set up monitoring. Small changes stop big infestations.
DIY methods that work
For small outbreaks, these steps usually bring numbers down within a few days. The key is removing the breeding source — traps alone will not solve the problem.
- Apple cider vinegar trap — a small dish covered with pierced cling film catches dozens of adults overnight.
- Red wine or beer trap — the fermenting smell is highly attractive to fruit flies. Change daily.
- Drain scrub — use a long-handled brush and biological drain cleaner to remove slime in U-bends and gullies.
- Bleach rinse — a dilute bleach flush kills larvae in drains, but follow with enzyme treatment to break down residue.
- Fruit bowl management — store ripe fruit in the fridge, compost scraps immediately and rinse recycling containers.
- Bin hygiene — use bins with tight-fitting lids, empty daily in warm weather and wash the bin weekly.
Prevention checklist
Once the flies are gone, keep them away with these daily and weekly habits.
- Store fruit in the fridge and check fruit bowls daily for over-ripening.
- Rinse bottles, jars and cartons before putting them in recycling.
- Clean drains weekly with a biological or enzyme-based product.
- Empty indoor bins daily and use bins with sealed lids.
- Wipe down splashbacks, worktops and under small appliances every evening.
- Fit fine-mesh drain covers to stop flies entering from sewer lines.
Commercial kitchens, pubs & food businesses
Fruit flies are endemic in hospitality — beer lines, drip trays, fruit garnishes and waste bins provide ideal breeding conditions. Our commercial programme combines deep-source treatment with proofing advice and ongoing monitoring.
- Clean beer-line drip trays and drains every service — fruit flies breed in the smallest amount of spilled beer or yeast.
- Install insect-proof screens on back-of-house windows and self-closing doors on kitchen entrances.
- Use lidded food-waste caddies and position external bins away from delivery and prep doors.
- Schedule weekly deep cleans of under equipment, kick-plates and sink gullies where residue hides.
- Keep a log of fly sightings and trap counts — this helps identify seasonal patterns and target problem areas early.
