The foreign grain beetle, Ahasverus advena (Walt.), is a worldwide pest named for wreaking havoc in grain storage facilities. These pests gravitate to damp and moldy grains.
This pantry pest is a scavenger who feeds on grain, but also on animal (including dead insects) and plant debris and the fungi which grow on them. This makes them a serious pest in homes and businesses with major moisture problems. They have been known to feed on mould in wet bathrooms.
Adult foreign grain beetles are between 1/16” to 1/8” long, with flattened, reddish-brown bodies. They are covered with short hairs. Their antennae have a three-segmented club, and are less than half their body length. All 4 corners of their prothorax stick outward and have a round lobe at their tip. They have wing, which are covered with many rows of tiny punctures. Adult foreign grain beetles are strong flyers and they are attracted to lights at night.
