Tiny Brown Beetles in Home: Stored Product Pests, Not Woodworm

A UK homeowner finds tiny brown beetles on upper hallway, attracted to light. Smaller than a grain of rice, appear larger when wings open. Pest control said they're grain beetles, harmless, no treatment. Homeowner worries about migration to kitchen, possible link to past rat infestation and leftover bait in loft. Asks about fumigation, bay leaves.

Expert Advice

Likely a stored-product beetle: drugstore beetle, cigarette beetle, carpet beetle, or larder beetle. All infest stored foods and some fabrics. Could originate from rat nests containing nuts/dry food. Fumigation is expensive and may not work. Better to inspect, remove nest material/food, and treat with dust insecticide if needed. Bay leaves are ineffective.
