Sawtoothed Grain Beetles in Georgia

Adult Sawtoothed Grain Beetles are small, red to brown colored beetles ranging from 0.25-0.3 cm in length. Identification can be aided by looking at the thorax (second section of an insect right behind the head) of the beetle. They have small projections coming off either side of their thorax in a row. They have a wide variety of stored goods that they infest; many are the same goods that Indian Meal Moths frequent. Oatmeal, seeds, chocolate, dog food, bird seed, cereal, and so forth all fall prey to these beetles.

Their small size allows them access into all sorts of stored goods. They either gain access through small holes or imperfections in the packaging or they wait until the item has been opened and then make their way inside. Their feeding can decrease the value of the product, make it unfit for use, and even encourage fungi and bacteria growth where they damage different goods.
