Mold Mite

Natural Habitat

Typically found in environments with high humidity (over 60%) where mold and fungi grow, such as bathrooms, kitchens, and damp basements.

Diet & Feeding

Feeds primarily on fungi, molds, and yeasts, but can also consume high-protein organic materials like grains and seeds.

Behavior Patterns

They appear as small, moving white specks or 'dust.' They mature rapidly from egg to adult in under three weeks in optimal moist conditions.

Risks & Benefits

They do not bite or sting but can cause skin irritation or allergic reactions (dust mite-like symptoms) in sensitive individuals. They indicate a moisture or mold problem that needs addressing.
