Dust Mite

Natural Habitat

Indoor environments, particularly in mattresses, pillows, carpets, and upholstered furniture.

Diet & Feeding

Dead human skin cells, pet dander, and some fungi.

Behavior Patterns

Dust mites are microscopic arachnids that thrive in warm, humid environments. They lack eyes and respiratory systems, absorbing moisture directly from the air. Their life cycle includes egg, larva, nymph, and adult stages, lasting about 1 to 2 months.

Risks & Benefits

Dust mites are a major source of indoor allergens, which can trigger asthma and allergic rhinitis in sensitive individuals due to proteins found in their feces and decaying bodies. They do not bite or transmit diseases. They serve as a food source for some predatory mites.
