Learn About Fruit Flies

Learn About Fruit Flies

Before we get into the specifics of how to keep fruit flies out of your compost bin, it’s important to understand a little bit about these insects. Fruit flies are attracted to decaying organic matter, which is why they’re often found near garbage cans or in kitchen compost bins. These insects lay their eggs in decaying fruit or vegetable matter, and the larvae then feed on the decaying material.

Fruit flies are small – about 1/8 of an inch long – and they have red eyes and black bodies. You’ll often see them hovering around overripe veggies, fermenting liquids, and garbage cans. They are attracted to sugar, so they’re also often found near soda cans or other sugary drinks.

And while fruit flies aren’t dangerous, they can be a nuisance – and they can contaminate your food scraps if they lay their eggs in them.

Why are the Fruit Flies Attracted to Kitchen Compost Bins?

Why are the Fruit Flies Attracted to Kitchen Compost Bins

The sight of a fruit fly hovering near your compost bin may be enough to make your skin crawl. But what is it about rotting fruit and vegetable scraps that attract these pesky insects?

As it turns out, fruit flies are attracted to the same things that make compost such a valuable resource for plants. When organic matter decomposes, it produces heat, moisture, and a number of gases, including methane and carbon dioxide.

These conditions are ideal for fruit fly reproduction, and the insects can lay their eggs in a moist environment very quickly. The resulting larvae then feed on the decaying matter, continuing the cycle of decomposition.

While the cycle of decomposition is essential for healthy compost, it’s also what makes fruit fly infestations so difficult to control. Because the insects are attracted to the conditions that are necessary for decomposition, it can be challenging to keep them out of your bin.

There are a few reasons why fruit flies might be attracted to your compost bin:

  • Fruit flies may be attracted to compost bins if they are near a garbage can or other organic matter source.
  • Another reason is that the compost bin might not be sealed properly, which allows fruit flies to enter.
  • And finally, the compost bin might not be aerated properly, which can also attract fruit flies.

Health Hazards of Fruit Flies

If fruit flies lay their eggs in your food scraps, the larvae can contaminate the food with their feces. This can make the food unsuitable for composting.

Due to their small size and high moisture content, fruit fly larvae are ideal hosts for disease-causing bacteria. The flies are attracted to ripe fruit and fermenting liquids, and they can lay their eggs in these substances.

When the eggs hatch, the larva will feed on the fruit or liquid, contaminating it with bacteria. In some cases, these bacteria can cause food poisoning or other illnesses. They can also spread diseases such as dysentery and typhoid fever. 

In addition, the larval stage is also when fruit flies are most likely to bite humans. These bites can cause irritation and swelling and, in some cases, can even lead to a dangerous allergic reaction.

So it’s important to take steps to keep fruit flies out of your compost bin.

How to Keep Fruit Flies Out of Kitchen Compost Bin? Follow These Steps

Seal Your Compost Bin Properly

One of the easiest ways to keep fruit flies out of your compost bin is to seal it properly. Make sure that the lid fits tightly and that there are no gaps or cracks where fruit flies can enter.

You can also line the bottom of the bin with a layer of newspaper or cloth. This will absorb any moisture that might be present, and it will also create an extra barrier that fruit flies will have to penetrate.

Use a screen or mesh to cover the top of your compost bin, which will further deter fruit flies.

Keep Your Compost Bin Clean

Fruit flies are attracted to decaying organic matter, so it’s important to keep your compost bin clean. Empty your compost bin regularly, and clean it out with soap and water if necessary.

You should also avoid adding moldy or rotting food scraps to your compost bin, as these will attract fruit flies. If you notice fruit flies in your bin, remove any moldy or rotten scraps and dispose of them in the garbage.

Another way to keep fruit flies out of your compost bin is to aerate it properly. The compost needs to be turned regularly to ensure that it decomposes properly.

Turning the compost also allows oxygen to circulate, which will help to deter fruit flies. If you notice fruit flies in your bin, turn the compost and add more airflow by drilling holes in the lid or sides of the bin.

Keep Your Kitchen Clean

Fruit flies can also enter your home through other sources, such as open doors or windows or cracks in the walls. They are attracted to rotting food and fermenting liquids, which can lead them to contaminate surfaces in your kitchen with disease-causing microbes.

So it’s important to keep your kitchen clean and free of food scraps. Wipe down surfaces regularly, and vacuum or sweep the floors to remove any food crumbs that might attract fruit flies.

You should also empty your garbage can regularly and avoid leaving any food scraps or other organic matter out in the open.

Screen doors and windows can help to keep fruit flies out, and you can also use traps or insecticides to keep them from entering your home in the first place.

Store Your Food Scraps in the Fridge

If you’re concerned about fruit flies getting into your food scraps, you can store them in the fridge until you’re ready to add them to your compost bin. This will keep the food scraps fresh and will deter fruit flies.

You can also store your food scraps in a sealed container, such as a plastic bag or container with a lid. This will keep fruit flies out and will also prevent food scraps from attracting other pests, such as ants or rodents.

Add a Layer of Dry Leaves to Your Compost Bin

One way to keep fruit flies out of your compost bin is to add a layer of dry leaves or other organic matter on top of the food scraps. This will create a barrier that fruit flies will have to penetrate and help keep the food scraps fresh.

You can also add a layer of paper or cloth to your compost bin. By doing so, moisture will be absorbed, and fruit flies will be inhibited from breeding.

As a result, fruit flies will be discouraged from laying their eggs in the food, and mold and bacteria will be prevented from growing on it.

Use a Fruit Fly Trap

If you’re still having trouble with fruit flies, you can use a fruit fly trap to catch them. There are a number of different types of traps available in the market for capturing fruit flies.

Fruit Fly Trap

One type of trap uses sticky paper to catch the fruit flies. The paper is placed inside the trap, and the fruit flies are attracted to it and get stuck.

Fruit Fly Trap

Another type of trap uses liquid bait to attract the fruit flies. The fruit flies are drawn to the bait and then drown in the liquid.
