Sawtoothed Grain Beetle

Natural Habitat

Found in households, pantries, food processing plants, and storage facilities, particularly where cereals, grains, and other dry food products are stored.

Adults are long-lived (6-10 months) and can produce several generations per year under optimal conditions. They are active and can quickly move between food sources. Females lay eggs directly on food, and larvae develop within the food product. They are not strong flyers but can disperse quickly through crawling or transport in infested goods.

Risks & Benefits

Potential risks include contamination and spoilage of stored food products, leading to economic losses and potential health concerns if infested food is consumed. They are not known to bite or carry diseases but are a significant pest of stored food. There are no known benefits.
