Grain Mite (also known as Flour Mite)

Found in environments with high humidity and food sources, such as pantries, kitchens, grain silos, and warehouses. They thrive in stored dry goods like flour, grain, cereal, cheese, and pet food.

Feeds on fungi (mold) growing on food products, as well as grain germ, cheese, flour, and other stored dry commodities. They are strongly associated with fungal growth.

They reproduce rapidly in humid conditions. When populations explode, they create a 'brown dust' layer on food surfaces that appears to move. Under adverse conditions, they can enter a dormant 'hypopus' stage where they are resistant to drying out and starvation.

Risks: Major pest of stored food products; infestation renders food inedible and gives it a sickly sweet or minty smell. They can cause allergic reactions (baker's itch) and respiratory issues in sensitive individuals. Benefits: They are decomposers in the wild but have no significant benefits in a domestic setting.
