Merchant Grain Beetles

Anobiid and Lyctus species


Merchant grain beetles are typically not found in grain products, but instead like to attack cereals, cake mixes, macaroni, cookies and chocolate. Merchant grain beetles are dark brown and have six saw-like teeth on each side of their bodies. They can grow to be one-eighth of an inch long and have very flat bodies.


The merchant grain beetle’s body shape allows it to crawl into packaging to eat, live and have babies.


Merchant grain beetles can infest stored food products and can contaminate food.
