Confused flour beetles get their name from their shocking similarity to red flour beetles, which causes some confusion over their identity. In addition to looking nearly identical, confused flour beetles and red flour beetles live in the same environment and compete for resources. Both types of flour beetles infest grain products and may even sneak into cracks and crevices where grain may have spilled. From cereal and cake mix to cornmeal and dry pet food, larvae and adults alike feed on all sorts of dry goods.

Confused Flour Beetle Behaviors, Threats, or Dangers

Though confused flour beetles are not known to bite humans or spread disease, they can cause an unpleasant odor and may promote mold growth in your food. Since the beetles are attracted to grain with a higher moisture content, they often cause a slight gray tint to the grains they are infesting.
