Put a stop to rats and flies in compost

Updated on 4/11/2025 Posted on 23/9/2022

Composting is a pest-free process when done correctly. Rats, flies and other pests are a nuisance caused by either the process going awry or by something that was added.

What can go wrong to attract pests?

Pests track their food through smell, which may be faint and barely detectable by you. The most common causes of pests in traditional compost bins include:

  • Lack of oxygen. Poor mixing can result in partially aerated wastes emitting odours.
  • Water everywhere. The water makes the wastes soggy, and as a result, smelly.
  • Waste imbalance. A smell of ammonia indicates a part of the waste has ceased composting.
  • Wrong waste added. Adding food waste like meat, cheese and bread, can attract pests.

Our general advice for pest-free composting is follow your compost system’s operating instructions. Neglecting for example, to aerate by mixing or to leave out specific types of waste, can create conditions that attracts rats and flies to traditional compost bins such as bottomless bins and tumblers.

Use the most suitable compost system

Traditional compost bins are typically inexpensive basic composters. They suit garden wastes which don’t attract rats and flies. With limited ability to handle food scraps, problems with pests will arise if enough caution isn’t taken about adding the types and amounts of kitchen scraps.
