Damage and controlīecause bread beetle larvae thrive in dark, warm, undisturbed places, it is essential to search thoroughly for the food-source of the larvae if adults are found wandering around. Before emergence as an adult beetle, a minimum of nine days is spent as the pupa in an oval shaped cell that is moulded by the larva using the food material. The larva increases in size and, at about 5mm in length, it enters the pupal stage. In its search for food, it may bite into packaged or hidden food sources. The outside of the cover is etched in parallel rows of grooves or pits, which should aid quite a bit in identification. Perhaps the most distinctive feature is the unique wing covers. Body: The pest is oval-shaped. Wings: The wing covers are lined with parallel rows of deep pits or punctures.The adult beetles can fly, and they are attracted to light.
