Dust Mite

Scientific Name: Dermatophagoides spp.

Order & Family: Astigmata (order), Pyroglyphidae (family)

Size: Approximately 0.2-0.3 mm (0.008-0.012 inches) long, invisible to the naked eye.

Dust Mite

Natural Habitat

Found in human dwellings, particularly in bedding, carpets, upholstered furniture, and clothing. They thrive in warm, humid environments.

Diet & Feeding

Primarily feed on organic detritus such as shed human skin flakes (dander), as well as pet dander and fungal spores.

Behavior Patterns

Dust mites are microscopic arachnids that avoid light and prefer dark, moist environments. They reproduce quickly, with females laying up to 100 eggs in their lifetime. Their life cycle from egg to adult is about 3-4 weeks. They do not bite or sting.

Risks & Benefits

Potential Risk: A major trigger for allergies and asthma in sensitive individuals due to allergens in their feces and body fragments. Symptoms can include sneezing, runny nose, itchy eyes, eczema, and respiratory problems. Potential Benefit: Their role in decomposition of organic matter is negligible in human environments due to their microscopic size and specialized diet.
