Flour beetles (Tenebrionidae – Tribolium spp.)

Flour beetles are small, brownish in color and elongate in shape. There are nine species that are potential pests in stored food products.  Two species are very common.  The confused flour beetle (Tribolium confusum) is common in northern regions and the red flour beetle (Tribolium castaneum) is more common in southern areas. They feed on  barley, beet pulp, breakfast cereals, grains, nuts, wheat, wheat bran, milk chocolate, dried milk and occasionally hides.  Good sanitation is key to controlling these beetles.  Freezing stored products at -4 degrees for 24 hours will kill all stages, as will heating at 122 degrees for an hour.

Drugstore beetles (Anobiidae – Stegobium paniceum)

These beetles have a hood-like thorax which hides the head when viewed from above.  They are reddish brown in color and rounded in profile and oval-shaped.  They feed on a variety of products including tobacco, seeds, grain, nuts, beans, spices, dried fruits and vegetables, flour, rice,ginger, yeast, herbs, paprika, dry dog and cat food, cocoa, biscuits, raisins, dates, alfalfa, hay, almond hulls, barley, corn meal, rice meal, wheat bran and even rodenticides.   They are good at penetrating packaging to get access to food.  The same control methods recommended for flour beetles will work on this species.

saw toothed beetles

Saw-toothed grain beetles (Silvanidae – Oryzaephilus surinamensis)

Saw-toothed grain beetles small, black, elongate and have six distinct saw-like teeth on each side of the thorax.  They are commonly associated with breakfast cereals and is frequently found in corn meal, flour, biscuit mix and processed cereals as well as in alfalfa seed, almonds, baking soda, barley, candy, clover seeds, chocolate, sugar, rice, wheat, cereals, dried fruits, corn, cornmeal, corn starch, flour, garbanzos, hay, honeycomb, milo, mixed feeds, oats, raisins, rice, figs, peas,  pecans, dried meat and tobacco.  Sanitation and freezing and heating will also work on these beetles.


larder beetles

Hide & Larder beetles (Dermestidae – Dermestes spp.)

Dermestid beetles are larger than other stored product beetles, reaching a 1/3 of an inch long.  The hide beetle is brown on top and white on the bottom and the larder beetle is brown with a broad cream-colored band across the front of the abdomen.  These beetles prefer animal products such as leather goods, hides, skins, dried fish, pet food, bacon, cheese and feathers.  They can be a major pest in museums.  Sanitation is important and sticky traps can be used on flat surfaces to catch adult and larval dermestid beeetles.

Weevils (Curculionidae – Sitophilus spp.)

Weevils are easily recognized by their small size and prominent snout.  They are very destructive of stored grains in the world.  They will feed on chick peas, corn, oats, barley, rye, wheat, kafir, buckwheat and millet.  They are frequently found in macaroni and noodles.  When you find any of these beetles in your home, inspect all open dried foods and toss anything that is infested. Place all non-infested foods in sealed containers or refrigerate them.  Completely clean the pantry where the foods are stored to get any larvae that may be crawling around.  Then lightly dust the shelves with food-grade diatomaceous earth before putting the foods back.
