Mold mites are small but mighty arthropods that love to feast on mold and other fungi. Like other types of mites, mold mites can trigger an allergic reaction and cause skin irritation. Knowing how to spot them, get rid of them, and prevent them will help you keep your household safe.

What Are Mold Mites?

Mold mites are a type of arthropod related to ticks. They're found around the world and, despite their name, eat a varied diet that includes fungi, decaying wood, animal carcasses, and bacteria. The scientific name of one of the most common species of mold mite, Tyrophagus putrescentiae, actually translates to "cheese eater."

What Mold Mites Look Like

6 ways to identify mold mites, including length, color, and location

A single mold mite measures less than half a millimeter in length and is nearly transparent. They may be white or light tan in color and don't have wings. Since they are so small and practically clear, it's nearly impossible to see an individual mold mite with the naked eye.

However, when mold mites come together, they tend to be very visible. A mass of mold mites looks like a white or gray fuzz, or biomass, found in areas with mold or nearby food. If you look at the mass using a magnifying glass, you may be able to see it moving.

Signs of Mold Mites

One surefire sign of mold mites is visible mold in an area. Another way to tell if you have the mites is to look for white, gray, or brown dust. 

When conditions become less than desirable, mold mites start to move in search of greener pastures. You can often see this movement, which looks like dust or fuzz migrating across a surface.

Are Mold Mites Dangerous?

While mold mites aren't fatal to humans, they can cause allergic reactions and irritation. Plus, the mites accompany a mold infestation, which can be dangerous in and of itself. According to the Centers for Disease Control and Prevention (CDC), mold can cause respiratory illness. Depending on where it grows, it can also cause structural damage to your home.

How to Get Rid of Mold Mites

The best way to get rid of mold mites is to get rid of their food source: mold. The way you should get rid of mold depends on the type of surface it's on and the location. For example, you can kill mold on wood by deep cleaning it with vinegar and water. To get rid of mold in a bathroom, you may need to reduce the humidity and deep clean surfaces.

You don't need to use particularly strong cleaners, such as bleach, to get rid of mold. Vinegar, tea tree oil, and other options can kill mold naturally and eliminate mold mites.

Of course, there may be cases where you need to call in a professional to do the job. If the mold is extensive or you're concerned about your safety, consider hiring a local mold removal pro. You may want to hire a local pest exterminator to get rid of the mites and a local general contractor to evaluate any damage caused by the mold. 

How to Prevent Mold Mites

Just as removing their food source is the best way to get rid of mold mites, preventing mold growth is the ideal way to prevent the mites from getting into your home. Create conditions that are inhospitable for mold by:

  • Using a dehumidifier

  • Improving airflow and ventilation

  • Cleaning or replacing HVAC and AC filters regularly

  • Clean spills or moisture quickly

  • Keep your home clean

Frequently Asked Questions

Mold mites will usually not go away on their own, as long as there continues to be a source of food for them. To ensure that they go away and to keep them from returning, you'll need to get rid of the mold or any other food source. Even if you successfully remove an infestation, more mites are likely to return if you don't get rid of the mold.

Mold mites don't live very long, usually less than 30 days. But they multiply rapidly. Since female mites can lay up to 800 eggs before they die, it's very easy for mites to easily invade a space and continue to infest it, even after the initial invaders have died off.

The average mold remediation cost is $2,360, but the final price tag varies based on several factors, including the size of the problem, its location, and the type of mold. The materials that need treatment will also affect the total cost of the remediation. For example, removing mold from drywall tends to cost more than removing mold from flooring.
