Can Fruit Flies Carry Diseases?

Prevention is the best way to avoid any problems with fruit flies, here are some tips:

  • Clean up any spilled food or liquid on counters, near garbage cans, in cupboards, etc…
  • Eat or throw away any over ripe fruit
  • Keep an eye on your recycling bin, the flies love food residue left on cans and bottles
  • Take out the garbage on a regular basis

If you already have a problem with the flies you’ll want to eliminate any food source. Once you eliminate all food sources that could attract the flies, you’ll want to thoroughly clean all surfaces where the flies could’ve laid eggs. This is important because while you may not see any flies, their eggs may still be in hiding.  Doing a good deep clean is usually effective against the fruit flies.

If you’d like to trap the adult fruit flies, many people have success with setting out bowls of dish soap and vinegar, red wine or even rotting fruit covered with saran wrap and a small hole poked into it; the flies go in but can’t find their way out.

Fruit flies may be a nuisance in the house but the tiny flies are beneficial; fruit flies are often used in college science labs, they’re used to help develop new mosquito repellents and fruit flies are even used to research human genetics.
