Beetle total number of known species exceeding 300,000. In North America alone there are 111 families with roughly 30,000 species. They range in size from 0.25 mm up to 200mm. In general, beetles can be distinguishing from other insects by the following anatomical characteristics: opaque armored forewings which adjoin in a straight line down the center and cover the hind two thoracic segments and most of the abdomen, chewing mouth parts, two compound eyes and antennae that attach to the head between these eyes.
Stored Product Insects
Some of the stored food pests, and a variety of other beetles that frequently invade human habitations, can also damage clothing, carpets and other household furnishings, attacking almost anything made from natural fabrics and furs.
Powder Post Beetles
Powder post beetles are so called because in high numbers they are able to turn the inside of a piece of wood into nothing more than a mass of fine powder. These wood destroying insects can do significant damage to structural timbers, wood floors and any other wood products. Powder post beetles are small (1/8 inch) and the adult beetles are seldom seen. Most of the life cycle is spent in the grub or larvae stage eating wood.
Damage is done by the larvae as they create narrow, meandering tunnels in wood as they feed. This stage can last between 1-10 years depending upon a number of factors; these include species of beetle, type of wood infested, age of wood, moisture content of wood and air temperature. The exit holes are very small, about the size of a pin head and usually fine dust will drop from these holes.
Carpet Beetles
Carpet beetles are destructive pests of natural fibers, fur, leather, and other animal products. They can also damage furniture, clothing, shoes, natural fiber rugs and other goods. Sowbugs & Pillbugs
Sowbugs and Pillbugs are grey/brown in color, commonly found where conditions are damp enough for them to survive such as basements, crawlspaces and old foundations or floors where dampness is a chronic problem.
