Red Flour Beetles

If you see a reddish brown beetle about 1/8 in long and/or a larvae about 1/8 in to 1/4 in long in food areas, it is probably the Red Flour Beetle. You might ask: How did I get these in my home? Generally they are brought in on products that were not inspected and/or processed properly.

Red Flour Beetle females deposit about 300-500 clear white sticky eggs on or among food materials, in cracks, in bags, or through the mesh sacks containing food. The female repeats this egg-laying process 2-3 times per day and typically lives 2-3 years. So as you can see, they can multiply very rapidly.

Red Flour Beetles are known to attack grains and grain products, peas, beans, shelled nuts, dried fruits, pet foods, cereals, bird seed, spices, milk chocolate, drugs, cayenne pepper, and/or museum specimens. They are very attracted to flour of high moisture content.


You need to inspect products for the source of the infestation and remove all infested products and place in a sealed garbage container outside of the home. Chances are that other products are infested without visual evidence of infestation; so it is best to remove all potential sources of infestation. NOTE: Spices in glass or metal containers do not have to be removed unless infestation is sighted. Clean the infested areas with a vacuum cleaner and/or wipe with soapy water.

After inspection, removal of infested products and cleaning; we will treat the problem areas with a water based material that will provide continuous control for up to 60 days. Normally a one-time application will take care of this problem. Complete results can normally be achieved in 4 to 6 weeks. By this time all hidden eggs will have hatched and the larvae and/or adults will come in contact with the treatment.
