About this bug

A tiny, tan fly with bright red eyes that hovers over ripe fruit, drains, trash and spilled drinks. It can go from egg to adult in about a week.

You'll usually find fruit flies in the kitchen. They are most active in spring, summer and fall.

When you'll see fruit flies

Fruit Flies are most active in spring, summer and fall. In spring, overwintering adults become active and many species lay their first eggs. Summer heat speeds up development, so populations can grow quickly. In fall, many bugs look for shelter, and some move toward or into buildings.

Typical places to check: kitchen.

About flies & mosquitoes

The fruit fly is one of the flies & mosquitoes. Flies have only one pair of working wings; the second pair is reduced to small balancing knobs called halteres. They go through complete metamorphosis, and the larvae, called maggots, need moist organic material such as garbage, soil, drain film or standing water.

Fly problems are almost always breeding-site problems. Finding and removing the moist material where larvae develop works far better than swatting adults.

What to do about it

  1. Refrigerate or toss overripe fruit and rinse recyclables
  2. Set a trap with apple cider vinegar and a drop of dish soap
  3. Scrub drains and trash cans to remove breeding film
