Red and confused flour beetles infest a wide variety of stored products, particularly those containing processed meal or flour. They are not able to infest whole seeds unless the seeds have already been broken open. Infestations often originate from birdseed, dry pet foods, baking ingredients, pasta, and spices, usually in the oldest, most difficult to reach packages.
The most important management step is to find and remove infested products. If help locating infested product is needed, floor pheromone traps are the most effective at capturing adults of these flour beetles. Adults may also hide around infested products in cracks and crevices, which can be treated with an appropriately labeled insecticide.
