- LESSER GRAIN BORER. Both adults and larvae bore into grain kernels. Adults are reddish-brown and about 3mm long. Larvae are white with a small brown head and short legs.
- RED FLOUR BEETLE. The flour beetle is about 3mm long and infests flour and meal. They can get into packages through very small openings.
- SPIDER BEETLE. Spider Beetles are general scavengers and can be found in pantries, museums, grain mills, warehouses, and attics that contain bird or rodent droppings.
- CARPET BEETLE. Most adult carpet beetles are about 2mm long and varied in color. They can have several generations per year.
- SILVERFISH. Silverfish typically feast on cellulose, but you may find them lurking in the pantry because of the warmth and the amount of cardboard and paper containers.
- ANTS. Ants are a common household pest, often entering structures in search of food or water (particularly during dry or hot weather), or to escape flooded nests during periods of heavy rainfall.
Lesser Grain Borer
Both adults and larvae bore into grain kernels. Adults are reddish-brown and about 3mm long. The head is bent underneath the body. Larvae are white with a small brown head and short legs.

This moth has a wingspread of about 25mm and has characteristic markings on the wings. Larvae look like the Indian meal moth larvae only larger. They feed on a variety of products and prefer grains etc that are moist or in poor condition.
Mites are most often found in grain that has gotten wet or out of condition. They are about mm long, grayish white, and have long hairs growing from the body. Large numbers can cause grain to smell bad.
The American roach is much larger than the German roach and not as prevalent. Average length is about 25mm (1 inch).

This stage lasts about a year before they become adults.
