Description:

FLATGRAINBEETLEoctSeveral species of grain beetles cause problems in homes and businesses alike. The pantry pests attack stored grains, cereals, flour, spices, and other processed food products. Grain beetles are commonly encountered in a variety of manmade structures, such as grain elevators, warehouses, mills, home pantries, and railroad cars and cargo ships which transport food items. With their flattened bodies, most adult grain beetles can easily penetrate and hide in cracks and crevices. While the insects are not known to carry or pass any diseases to humans or pets, they make pantry products unfit for consumption. Grain beetle infestations can cause granaries, warehouses, mills, and even retail establishments to lose business and profits over time. Grain beetles feed on nearly any stored food product, particularly cereals, breakfast foods, flour, dried fruits and meats, pet foods, and many other items.
