Flour beetles are small insects belonging to the family Tenebrionidae. They are commonly found in stored grain products, such as flour, rice, and cereals. These pests can be identified by their reddish-brown color and elongated bodies, typically measuring about 1/8 to 1/4 inch in length. There are two main species of flour beetles: the red flour beetle and the confused flour beetle. Both species thrive in warm, dry environments and can reproduce quickly, leading to infestations in pantries and food storage areas. Proper storage and regular cleaning can help prevent their presence.
