You may not be doing anything to attract fruit flies to your Pittsburgh home. This is a somewhat unique pest. It can get into your home from the outside, but more often than not, it is carried into your home. Let's take a closer look at these mysterious little flies.


It is important to make sure that the flies you're finding inside your Pittsburgh home are actually fruit flies. There are some flies that are mistaken for fruit flies, though they shouldn't be because they don't look anything like fruit flies. Cluster flies, which look like large, dark house flies, can get into a home in large numbers. Aside from their large numbers, they have nothing else in common with fruit flies. The fly that is most often mistaken for the fruit fly is a fungus gnat. This is because fruit flies and fungus gnats can create a swarm in your house and they appear as nothing more than a little speck flying around in the air. The big differences are that fungus flies are black and they land and run across surfaces. Fruit flies are tan with red eyes and they fly away when you approach them.

What Attracts Fruit Flies?

If you have something around your home that is attracting fruit flies, it is likely to be one of the following:

  • An open trash can with rotting organic matter inside.
  • A fruit tree with rotting fruit lying on the ground beneath.
  • Berry bushes that are not protected by netting.

How Do Fruit Flies Get Inside?

They can come in through an open door or an open window with a damaged screen but it is more likely that they will come into your home inside eggs that are attached to a piece of fruit or a vegetable. These eggs hatch a few at a time. This can make it seem like fruit flies are reproducing like crazy in your home. The first day you see them, there are one or two specks flying around. The next day there are half a dozen, and soon there is a swarm. While fruit flies reproduce surprisingly fast, they're not that fast. The best way to prevent eggs from hatching is to put produce in the refrigerator because they hatch at room temperature.

Commonly Asked Questions About Fruit Flies

Are fruit flies harmful? Yes. Fruit flies can be harmful--in a way. While they don't bite or sting, they can spread bacteria from dirty locations to sensitive locations such as food-prep surfaces and dishes. But they are mostly nuisance pests.

How do fruit flies come out of nowhere? It can seem like they come out of nowhere because their eggs are so tiny. When they lay eggs on a piece of fruit that is sitting on your kitchen island or on the dining room table, you're not going to know it. They can also breed in hidden locations, such as decaying organic material inside your kitchen trash bin or inside some fermenting liquid in a can that is sitting in your recycling bin.

Do fruit flies die on their own? Yes. But it can take up to 50 days for a fruit fly to die. While you're waiting for fruit flies to die, they'll be creating more fruit flies in your home, lots more fruit flies! It is best to get rid of them before you're overrun with flies.

How fast do fruit flies reproduce? It takes around 18 days for fruit flies to go from eggs to sexually active adults, and a female fruit fly can lay as many as 500 eggs. It isn't going to take long for you to be overrun with these flies.
