|---|---|
Carpenter ants (wood destroying) | Carpenter ants are large ants and can be 1/2 inch to 1/4 inch in length. They are black or red and black in color. They are a pest because they commonly make nests in homes. Carpenter ants do not eat wood, but they will excavate it for nesting and occasionally cause structural weakening. |
Carpet beetles (food & fabric) | These are small, elongate or oval beetles ranging from 1/10 to 1/3 inch long (for most species found in stored products) and varying in color and color pattern. They are most easily diagnosed as larvae which are often elongate and quite hairy or with distinctive tufts of hair, especially at the end of the body. |
Casemaking clothes moth (food & fabric) | Clothes moths are widespread pests of fabrics, wool, furs, and other items of animal origin. The two species of clothes moths common to Washington are the webbing clothes moth and the casemaking clothes moth. |
Centipedes (nuisance) | Centipedes are a class of arthropods related to insects. Centipedes are very fast moving and flat. Centipedes have a pair of poison jaws that assist them in overcoming prey. Hence they are considered beneficial predators. |
Clover mites (nuisance) | Clover mites are small (1/100 of an inch long), oval-shaped reddish-brown mites and occasional household pests. A clover mite's front legs are typically longer than the other three pairs of legs and can be mistaken for antennae. Clover mites feed on clover and grasses and do not bite humans or animals or cause structural damage, but they can be a nuisance |
Cluster flies (nuisance) | Cluster flies resemble house flies, but are larger and slower in movements. They are about 5/16 inch long, dark gray with black and gray checkered abdomens. Cluster fly larvae or maggots are parasites of earthworms. |
Cockroaches (nuisance) | Cockroaches are flat insects that are found in a variety of colors. There are four common pest species: The German cockroach, the American cockroach, the brownbanded cockroach, and the Oriental cockroach. The German cockroach is most commonly found in the Pacific Northwest. |
Crickets (food & fabric) | There are two major cricket species that may invade homes. These include field crickets and the house cricket. The house cricket is the most common home invader in our area. The house cricket adult averages about 3/4 inch long and is yellowish-brown or straw-colored, with 3 dark bands on the head. |
Cupboard beetle (food & fabric) | Cupboard beetles are a collection of beetle species that attack stored grain products or household foodstuffs. They range from 1/8 inch in length to a little smaller. They are variously colored, but tend to be brownish. Most of them can fly. Once established in food, populations of these insects can explode and move through the home and infest any exposed food. |
