Tyrophagus putrescentiae
- Order & Family
- Order: Sarcoptiformes; Family: Acaridae
- Size
- 0.3 - 0.5 mm (barely visible to the naked eye, appearing as moving white dust)
Natural Habitat
High humidity environments with abundant organic matter, such as kitchens, bathrooms, damp basements, or stored food containers.
Diet & Feeding
Primarily feeds on mold, fungi, and products high in protein and fat like grains, cheese, dried meats, and seeds.
Behavior Patterns
They reproduce rapidly in humid conditions (above 65% RH). They do not fly but can be dispersed by air currents or by hitching rides on larger insects.
Risks & Benefits
They do not bite or sting but can cause 'grocer's itch' or allergic reactions/asthma via inhalation or contact. They can contaminate stored food products but serve an ecological role in breaking down organic matter.
