Mold Mite

Natural Habitat

Found in environments with high humidity and mold growth, such as kitchens, bathrooms, and stored food products like grains, flour, and cheese.

Diet & Feeding

Primarily feeds on fungi, molds, and organic debris, though they also consume high-protein stored foods.

Behavior Patterns

They reproduce rapidly in warm, damp conditions. While they do not fly or jump, they can be spread by air currents or by hitching rides on other insects or animals.

Risks & Benefits

They do not bite humans or pets but can cause allergic reactions ('grocer's itch') and respiratory issues if inhaled in large quantities. They contaminate food supplies by introducing fungal spores.
