Houseflies in the Kitchen: Why They Keep Coming Back

A few flies in the kitchen can quickly become a daily nuisance, and they matter because they land on food and surfaces.

The short answer

Houseflies are drawn to food scraps, spills, open bins, ripe fruit and drains, and they enter through open doors, windows and gaps. Keep food covered, wipe surfaces, empty and clean bins daily, fix leaks, add fly screens and seal gaps. Persistent flies usually mean a breeding source nearby, such as a garbage area or drain, which needs cleaning or professional help.

What attracts them

• Food waste and unwashed dishes.
• Open or dirty bins.
• Spills and sticky surfaces.
• Ripe fruit and pet food left out.
• Nearby garbage, drains or drainage.

How to keep them out

1. Cover food and store it properly.
2. Wipe counters and clean spills.
3. Use lidded bins and empty daily.
4. Fit fly screens and seal gaps.
5. Clean drains and find the breeding source.

Hygiene

• Wash hands after contact with flies' landing areas.
• Discard food that flies have contaminated.
