How to Keep Flies Away from Compost: A Comprehensive Guide

Welcome to our detailed blog post that will provide you with practical tips on how to keep flies away from your compost. Composting is a wonderful and eco-friendly way to reduce waste, produce nutrient-rich soil, and contribute positively to the environment. However, dealing with flies buzzing around your compost can be quite annoying. But worry not! We’ve got you covered with effective strategies that are both natural and easy to implement.

Understanding the Fly Problem

Before we dive into solutions, let’s briefly understand why flies are attracted to compost in the first place. Flies are commonly drawn towards decaying organic matter as it provides them with a suitable breeding ground and abundant food sources. They may lay eggs on fruit peels, vegetable scraps, or other decomposing materials found in your compost pile.

The Dos and Don’ts of Composting


  • Cover your compost: Ensure that your compost bin has a tight-fitting lid or cover. This helps prevent fly access while still allowing airflow for decomposition.
  • Add brown materials: Increase the ratio of dry carbon-rich materials (like leaves or straw) in your compost heap. The drier texture makes it less attractive for flies.
  • Mix properly: Regularly turning or mixing your pile enhances decomposition while decreasing fly activity by increasing air circulation within the pile.
  • Bury fresh food scraps: Digging food waste deeper into the center of the pile discourages flies from reaching their desired breeding grounds closer to the surface.


  • Overwater: Excessive moisture can create a favorable environment for flies. Keep your compost damp rather than soggy.
  • Add meat or dairy products: These items tend to rot quickly and attract flies. It’s best to avoid adding them to your compost altogether.
  • Leave the lid open: An uncovered compost bin is an open invitation for flies to feast on the organic material inside. Always remember to keep it securely closed.

Natural Fly Deterrents

If you’re still facing fly problems despite following the dos and don’ts of composting, here are some natural deterrents that can help keep these pests at bay:

Citrus Peels

The strong scent of citrus fruits is known to repel flies. Adding orange, lemon, or lime peels directly into your compost helps create an environment that flies find unappealing.

Mint Leaves

Mint leaves have a refreshing aroma that humans love but flies dislike. Placing fresh mint leaves in and around your compost bin acts as a natural fly repellent.

Lavender Oil

The fragrance of lavender oil not only adds a pleasant scent but also deters pesky flies. Mix a few drops with water in a spray bottle and spritz it onto your compost pile regularly.

Troubleshooting Persistent Flies

If you’ve tried all the above tactics and still encounter persistent fly problems, consider these additional measures:

Cover With Fine Mesh Netting

A fine mesh netting placed over your entire compost area acts as an effective physical barrier against flying insects, including flies. Ensure that the netting is secure and doesn’t have any gaps or openings.

Use Fly Traps

If you’re dealing with an overwhelming fly population, placing fly traps near your compost can help in trapping and reducing their numbers significantly. There are both commercially available options and DIY trap solutions you can explore.

Maintaining a Fly-Free Compost

To maintain a fly-free composting experience:

  • Monitor regularly: Regularly inspect your compost pile for signs of excessive moisture or strong odors indicating improper balance.
  • Aerate frequently: Continue turning or mixing your compost to ensure proper airflow throughout the pile, discouraging flies from breeding.
  • Add beneficial nematodes: These microscopic organisms feed on fly larvae, helping control the overall pest population in your compost heap. You can find them at garden centers or online retailers specializing in organic gardening supplies.

We hope this comprehensive guide has provided you with valuable insights on how to keep flies away from your compost effectively. Implement these strategies alongside regular maintenance and enjoy a pleasant odor-free composting experience while contributing positively to our planet!
