Fruit Flies in the Kitchen: Where They Come From

Fruit flies seem to appear from nowhere, usually around a bowl of ripe fruit.

The short answer

Fruit flies are attracted to ripe or rotting fruit and vegetables, fermenting liquids, bins and damp mops or sponges. They often arrive on produce and breed quickly. Store fruit in the fridge or covered, clean spills, empty bins, wash drains and mops, and remove overripe produce. Once the breeding site is gone, populations drop in days.

Common sources

• Overripe fruit and vegetables.
• Spills of juice, beer or soda.
• Bins and compost.
• Damp sponges and mops.
• Drain film.

Stopping them

1. Remove or refrigerate ripe produce.
2. Wipe spills and clean bins.
3. Rinse bottles before recycling.
4. Clean drains and replace dirty sponges.
5. Cover food.

Check

• Look for larvae near rotting fruit and in drains.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
