Fruit flies are small, flying insects attracted to ripe or fermenting organic matter. In Southeast Alaska, they often become a problem in homes, restaurants, and grocery stores—especially during warmer months or when fresh produce is left out.

Fruit flies are most active during spring and summer, but indoor infestations can happen any time of year—especially in warm, humid environments. Once inside, they can thrive near food waste, compost, and moisture sources like drains.

Fruit flies often enter homes by hitching a ride on produce, especially fruit that’s already starting to ripen. They can also fly in through open doors or windows, drawn by the scent of fermentation, food scraps, or sugary liquids.

Fruit flies are most attracted to rotting fruit, fermented liquids like wine or beer, sugary residues, and organic waste. Open garbage bins, compost, and even damp mops or rags can provide enough material to attract and sustain a population.

Not usually. While they may seem to disappear temporarily, fruit flies will return as long as there’s a food source and breeding site available. Proper sanitation and targeted treatment are needed to fully eliminate them.

To prevent fruit flies:

• Store produce: Keep fruit and vegetables in the refrigerator or sealed containers.
• Clean drains: Regularly flush and scrub out sink drains and garbage disposals.
• Take out trash: Dispose of food waste frequently and keep garbage bins sealed.
• Rinse recyclables: Clean bottles and cans before putting them in recycling bins.
