Insect
Brown House Moth
Hofmannophila pseudospretellaAlso known as False Clothes Moth
Brown house moths thrive alongside human habitation, where their larvae feed on an astonishing variety of dry organic material including bookbindings, carpet fibers, dried grains, and bird nests. Unlike many moths that take flight readily, adults often scurry rapidly across walls and floors to seek dark crevices when disturbed. High relative humidity accelerates their developmental cycle, allowing populations to persist year-round inside heated homes and warehouses.

- Harmless to humans and pets, though larvae can damage stored food and natural fabrics.
Responsible observation

- Detection: Watch for rapid running along baseboards in dark pantries rather than sustained flight.
