Why Do Flies Love Compost?

Compost is a magnet for flies due to its ideal conditions for feeding and breeding. As organic substances decompose, they emit certain compounds and scents that act as signals to flies, indicating a plentiful supply of food and a favorable spot for reproduction.

The activity of flies and their larvae (maggots) in the compost, including crawling through it, actually aids in aeration. This movement, along with the droppings they leave behind, contributes positively to the compost’s decomposition process.

Eliminating Flies from Your Compost:

Reposition Your Compost Bin in Direct Sunlight

Fruit flies thrive in warm conditions, but not extreme heat. Placing your compost bin in direct sunlight will increase the internal temperature, effectively killing the fruit fly larvae inside.

Set Up a Vinegar Trap to Capture Adult Flies

Capturing adult flies reduces breeding. Pour apple cider vinegar into a jar (about an inch deep) and add a couple of drops of dish soap to reduce surface tension.

Cover the jar with plastic wrap, poke holes with a toothpick, and place it near your compost bin. Flies will enter and drown in the liquid.

Establish A Fruit Trap

If you don’t have apple cider vinegar, use sliced fruit or a banana peel in a jar, sealed and punctured like the vinegar trap. Position it near the compost.

Freeze Kitchen Waste Prior to Composting

To prevent introducing fruit fly eggs and larvae from store-bought produce into your compost, freeze your kitchen waste overnight in a plastic bag before adding it to the compost.

Add A Sprig of Fresh Mint to Your Compost

The scent of peppermint repels fruit flies. Placing a sprig of fresh mint in your compost bin will deter them.

Surround Your Home and Compost with Deterrent Plants

Fruit flies dislike certain plants like basil, peppermint, lemongrass, and lavender. Growing these around your compost area can help keep the flies away.

Incorporate Essential Oils

Essential oils such as lavender, lemongrass, eucalyptus, or peppermint can effectively repel fruit flies.

Apply a few drops around potential entry points to your compost bin and use them in a diffuser indoors for added protection.

Stratify Your Compost

This key composting practice not only helps avoid fruit flies but also enhances the quality of your compost.

After adding fresh organic waste, cover it with a carbon-rich layer. Options like dead leaves, shredded paper, cardboard, or soil will mask the scent of the fresh “green” organic materials, making it less attractive to fruit flies.

Enclose Scraps Before Composting

Before adding your kitchen waste to the compost, wrap it in newspaper or butcher paper. This reduces the smells that lure fruit flies.

Even if they enter the compost, they won’t be able to reach the waste. Plus, the paper will break down along with the organic material.

Securely Seal Your Composter

While compost requires air for the decomposition process, you can safeguard the bin against fruit flies.

Seal any openings of the compost bin and cover vents with mosquito netting. This method allows for necessary air circulation while keeping the flies out.

Are Fruit Flies in Compost Good or Bad?

Fruit flies play an important role in the composting process. They are known as primary consumers, meaning they help decompose materials, particularly those with fruit acids.

Although they can be annoying, they don’t cause harm to your compost. On the contrary, they are likely to aid in its breakdown and enrichment.
