The common bed bug (Cimex lectularius Linnaeus 1758) is an ectoparasite insect (a parasite which lives on the outside of the body of the host) of the family Cimicidae. Bed bugs feed only on the blood of humans and other warm-blooded hosts. Although they have a cryptic behavior and can conceal themselves in tight cracks and crevices, bed bugs are often found in bed parts, such as mattresses and box springs, hence the common name.

Carpenter ants get their name because they excavate wood in order to build their nests. Their excavation results in smooth tunnels inside the wood. Carpenter ants range in size from one-quarter inch for a worker ant to up to three-quarters inch for a queen.

Fleas are parasites that feed on the blood of any warm-blooded body. The most common species is the cat flea, which often feasts on cats, dogs and humans.

House Spiders

This is usually the spider most often encountered indoors. It is a nuisance pest, probably more because of its webs than the spider itself. This spider is found worldwide and is common throughout the United States and Canada.

Silverfish

This insect gets its name from its silvery, metallic appearance and fish-like shape and movements. Silverfish have no wings but are able to run very fast. They tend to hide their presence from humans which means any damage they cause could go unnoticed as well.

Subterranean Termites

Subterranean termites live in underground colonies or in moist secluded areas above ground that can contain up to 2 million members. They build distinctive "mud tubes" to gain access to food sources and protect themselves from open air. Termite colonies are organized into castes depending on tasks - workers, soldiers and reproductive. The characteristics of a subterranean termite are dependent on the termite's role in the colony. Cream-colored worker subterranean termites are 1/8 to 3/8's of an inch in length. Soldier subterranean termites are of a similar body length but are distinguished by their powerful mandibles. Soldier termites have cream-colored bodies and brown heads. Reproductive subterranean termites are approximately one inch long.
