American Cockroach
A large, reddish-brown cockroach that lives mostly in warm, damp places like sewers, drains, and basements, wandering indoors in search of food, water, or shelter from harsh weather.Argentine Ant
A tiny dull-brown invasive ant that forms enormous multi-queen "supercolonies" and follows long indoor trails to sweets and water, especially when the weather turns wet or hot and dry.Black Carpenter Ant
A large, dull-black ant that nests in moist or decaying wood, tunneling galleries to build its colony rather than eating the wood like a termite.Brown Dog Tick
A reddish-brown three-host tick that strongly prefers dogs as its host and is unusual in being able to complete its entire life cycle indoors, infesting homes and kennels.Brown-banded Cockroach
A small indoor cockroach that favors warm, dry, elevated spots throughout a building, named for the pale bands across its wings and abdomen.Eastern Subterranean Termite
A soil-dwelling, wood-eating social insect that is the most widely distributed termite species in the eastern United States and a major structural pest.Formosan Subterranean Termite
An invasive subterranean termite that builds enormous underground colonies and aerial carton nests, attacking structural wood and even living trees far faster than native termites.German Cockroach
A small indoor cockroach found worldwide in association with humans, living near food, water, and warmth in kitchens, bathrooms, restaurants, and food-storage areas.House Mouse
A small, gray-brown commensal rodent that lives in close association with people, nesting in walls, appliances, and stored goods, and known for droppings, gnaw marks, and a musky odor.Little Black Ant
A tiny, shiny jet-black ant native to North America that nests in soil and inside structures, follows visible foraging trails indoors, and turns up in kitchens and pantries hunting for food and a little moisture.Norway Rat
A large, stocky burrowing rodent that nests at ground level in and around buildings, contaminates food, gnaws structures, and can carry diseases that affect people.Odorous House Ant
A tiny brown-to-black household ant that gives off a sharp, rotten-coconut smell when crushed and trails indoors after sweets, especially in damp weather.Old House Borer
A longhorned beetle whose larvae tunnel for years inside seasoned softwood timbers, most often pine, slowly weakening structural wood in buildings.Oriental Cockroach
A large, dark, slow-moving cockroach that favors cool, damp places like basements, drains, crawl spaces, and outdoor foundation areas, and is often called a "waterbug."Pacific Dampwood Termite
A large, caramel-to-dark-brown termite of the Pacific coast that nests inside moist, water-damaged wood rather than in soil, found from British Columbia to Baja California.Pharaoh Ant
A tiny pale-yellow to reddish-brown ant that nests in warm, hidden voids inside heated buildings, forms sprawling multi-queen colonies, and is both the hardest household ant to control and a documented contamination concern in hospitals.Powderpost Beetle
A small reddish-brown wood-boring beetle whose larvae feed on the starch in hardwood sapwood, leaving round pinhole exits and a fine, flour-like powder that gives the group its name.Roof Rat
A slender, climbing rat that nests above ground in attics, trees, and dense vegetation, travels overhead along wires and rooflines, and is especially fond of fruit and citrus.Tawny Crazy Ant
A small, uniformly reddish-brown invasive ant that swarms in huge numbers across the Gulf Coast, moving in fast, erratic trails and nesting in soil, debris, and electrical equipment rather than in tidy mounds.Western Drywood Termite
A wood-nesting termite of the western U.S. that lives entirely inside dry, sound wood — framing, furniture, dead tree limbs — without any contact with soil, betraying itself mainly by piles of tiny six-sided fecal pellets.
