Dust mites are tiny, microscopic creatures that belong to the arachnid family, similar to spiders and ticks. They thrive in warm, humid environments and are commonly found in household items like bedding, carpets, and upholstered furniture. Dust mites feed on dead skin cells shed by humans and pets, making homes an ideal habitat for them. These creatures are not harmful in themselves, but their waste products can trigger allergic reactions in some people. Symptoms may include sneezing, runny nose, and itchy eyes. Regular cleaning and maintaining low humidity levels can help reduce dust mite populations in the home.
