What Are Mould Mites?

Mould mites, scientifically known as Tyrophagus putrescentiae, are tiny arachnids, barely visible to the naked eye. They thrive in environments where mould is present. Understanding mould mites, including their diet and behaviour, is crucial to effectively managing their presence in your home.

The Diet and Behaviour of Mould Mites

Mould mites primarily feed on mould spores and hyphae, making mould-infested areas their preferred habitat. This relationship between mould mites and mould is not incidental but symbiotic; mould provides the perfect food source and environment for mould mites to thrive. Where mould is found, particularly in warm, humid conditions, mould mites are likely to follow. They prefer areas with poor ventilation and high humidity levels.

Common Habitats for Mould Mites

Mould mites are commonly found in areas prone to high moisture levels and mould growth in your home. These include the bathroom, kitchen, around window sills and frames (where condensation and mould can be common), areas around water pipes, and in basements or cellars where the humid conditions are good for both mould growth and mould mite habitation. Understanding these habitats is the first step in addressing a mould mite problem.

Health Risks of Mould Mites

While mould mites themselves don't bite or sting, they can be hazardous to health. Mould mite allergens can trigger allergic reactions in sensitive individuals and children. Symptoms include skin rashes, itching and respiratory issues and aggravation of asthma. Additionally, their presence often indicates an underlying mould problem, which itself carries significant health risks.

Signs of Mould Mites

Identifying mould mites can be challenging given their small size, but signs of their presence include tiny whitish to brownish spots or clusters, known as 'hair clusters' (these are actually the long hairs on mould mite bodies). More commonly, they are identified through an allergic response. Mould mite infestations often coincide with visible mould growth, and this is another key sign to look out for.

How to Get Rid of Mould Mites?

The key to controlling mould mites is addressing the underlying mould problem. Here's how to get rid of mould mites:

  • Address the mould: Since mould mites feed on mould, their key to effective treatment - eliminate the mould, and you eliminate the mould mites' primary food source. This means thoroughly treating mould in your home, including in hidden areas and the airspace.
  • Reduce Humidity: Use dehumidifiers and ensure good ventilation to reduce the humidity levels in your home, creating less favourable conditions for both mould and mould mites.
  • Clean Regularly: Regular cleaning, including vacuuming with a HEPA filter vacuum cleaner, can help remove mould mites and their food source.
  • Professional Pest Control: For a significant mould mite infestation, consider hiring a professional pest control service. They may treat the property with an insecticide to kill the mites and advise on how to keep damp and mould at bay. However, the long-term solution involves addressing the mould problem.

Long-term Prevention

Preventing mould mites long-term involves maintaining a dry, well-ventilated home environment. This includes regular inspection for mould, particularly in areas prone to dampness, and addressing any mould growth promptly. Making environmental and behavioural changes to maintain a mould-free and less humid environment is essential for keeping mould mites at bay.
