How Do Fruit Flies Get In Your House – 7 Ways

Let’s take a look at the 7 most common ways that a fruit fly will get into your house.

How Do Fruit Flies Get In Your House Infographic

1. Window

The window has to be at the number 1 spot on this list! It is the most common reason why you get ANY fly into your house, not just fruit flies.

To combat this, you could either:

  • Keep windows closed
  • Buy an insect zapper
  • Get a covering for the window to stop insects from getting in

Keeping windows closed during hot days is a challenge. Fresh air is very welcome, right?

Flies can still get into your home when the windows are closed though!

2. Doors

Very similar to the window, doors are regularly opened to let visitors in or to let yourself in. When your door is open, you are exposing your home to a fruit fly.

The best way to combat this is to either:

  1. Buy a bug zapper
  2. Set up some fly traps outside your door, so they are attracted to them instead.

3. Drains

Fruit flies lay eggs in drain systems. If you did not notice a fruit fly in your home, you would also have missed it laying eggs in your drain system!

3 to 4 days later, the larvae is now a fruit fly. Each one of the eggs could hatch within minutes of each other, and you will notice a huge influx of fruit flies into your house.

4. Fruit

Fruit fly loves to lay their eggs inside your fruit. It gives the larvae something to eat as soon as they are born 1 day later.

You may have purchased the fruit earlier in the day, and when you bought the fruit into your home, you also welcomed the fruit flies too! How do fruit flies get in your house… you may have bought them in!

It takes a further 2-3 days for the larvae to develop into a fruit fly. Suddenly, you will notice a large influx of fruit flies… probably in your kitchen!

5. Vegetables

Not only do fruit flies like laying eggs in your fruit, but they also lay eggs in your vegetables! Why? Because once they hatch, the larvae will immediately begin eating whatever food it is in.

Let’s say you picked up some vegetables from a store earlier on in the day, and you have now transported them into your home. If there are any fruit fly eggs in the fruit, they will hatch into larvae within 1 day.

After 2-3 days, they will develop fully into fruit flies. That is when you will notice their presence!

6. Entry Points

If a fruit fly gets the scent of fruit in your home, it will use any way necessary to get in. Fruit flies can use small cracks and holes in the structure of your home to gain entry.

You should perform regular inspections around your home to seal up any gaps, paying particular attention to door and window frames.

7. Larvae

Flies may have laid eggs somewhere on the outside of your house, and the larvae have entered the building through a gap in the brickwork, through a window, or a door.

Fruit fly larvae are tiny and white… so you may not have noticed them get into your house until it was too late.

After 2-3 days, they will progress to become fruit flies.

What Causes Fruit Flies

Fruit flies are attracted to many things in your home. Mostly, fruit, vegetables, and a water supply (standing water attracts fruit flies).

If you suffer from a regular fruit fly invasion, then you should consider keeping fruit in a container, away from windows, doors, and other areas that fruit flies use to get into your house.

Also – you can buy traps or even make homemade traps to catch fruit flies. I like to use a bug zapper. All flying insects are attracted to this, and it stops them from flying towards my face, which is a bonus!
