Dust Mite

Natural Habitat

Human dwellings, especially in bedding, upholstered furniture, carpets, and clothing. They thrive in warm, humid environments.

Diet & Feeding

Dead skin cells (dander) shed by humans and pets. They also consume other organic detritus found in dust.

Behavior Patterns

Dust mites are microscopic arachnids that are not visible to the naked eye. They live and reproduce in dark, warm, and humid places. They do not bite or sting but their excretions and decaying body parts are significant allergens. Their populations can explode in suitable environments without proper cleaning.

Risks & Benefits

Potential Risk: A major allergen for many people, triggering asthma, eczema, and allergic rhinitis symptoms. They are not known to directly transmit diseases. No known direct benefits to humans, but as detritivores, they contribute to the breakdown of organic matter in indoor environments.
