Dust mites are tiny, microscopic creatures that belong to the arachnid family, which also includes 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 visible to the naked eye, typically measuring about 0.2 to 0.3 millimeters in length. While they do not bite or sting, their waste products can trigger allergic reactions in some people, leading to symptoms such as sneezing, runny noses, and asthma attacks. Regular cleaning and reducing humidity can help control dust mite populations.
