Dust Mites

Natural Habitat

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

Diet & Feeding

Mainly feed on dead human and animal skin flakes (dander), as well as other organic detritus.

Behavior Patterns

Dust mites are microscopic arachnids that are not parasitic but live in close proximity to humans. They are sensitive to light and low humidity, which is why they are typically found deep within textiles. They reproduce rapidly, with a life cycle from egg to adult taking about 3-4 weeks.

Risks & Benefits

Dust mites are a common trigger for allergies and asthma. Their droppings and body fragments can become airborne and inhaled, leading to allergic reactions such as sneezing, runny nose, itchy eyes, skin rashes, and respiratory issues. They pose no direct threat (do not bite or sting) and have no known benefits to humans or the ecosystem, other than decomposition of organic matter on a microscopic scale.
