Dust mites are microscopic creatures that live in household dust. They feed on dead skin cells and other organic matter. While dust mites are not typically harmful, they can cause allergies and asthma in some people. Checking for dust mites can help you determine if they are present in your home and if you need to take steps to reduce their population.
There are a few different ways to check for dust mites. One way is to use a dust mite test kit. These kits are available at most hardware stores and home improvement centers. To use a dust mite test kit, you simply place a small amount of dust in the kit and then send it to a lab for analysis. The lab will then tell you how many dust mites are present in the dust sample.
