Dust Mite

Natural Habitat

Indoor environments, particularly in bedding, carpets, upholstered furniture, and areas where human skin flakes accumulate. They prefer warm (20-25°C or 68-77°F) and humid (70-80% relative humidity) conditions.

Diet & Feeding

Primarily feed on dead human and animal skin flakes (dander). They also consume other organic detritus found in household dust.

Behavior Patterns

Dust mites are microscopic arachnids that thrive in indoor environments. They are not parasitic but live in close association with humans, feeding on shed skin cells. They reproduce rapidly under favorable conditions. Their fecal pellets and body fragments are significant allergens.

Risks & Benefits

Risks: Dust mites are a major allergen for many people, contributing to asthma, allergic rhinitis, and eczema. Their fecal matter contains enzymes that can trigger allergic reactions. Benefits: No direct human benefits; they are part of the decomposer community in indoor ecosystems, breaking down organic matter.
