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.
Bed Bug
A small, flat, reddish-brown blood-feeding insect that hides in beds, furniture, and cracks near where people sleep and feeds on human blood at night.
Brown Marmorated Stink Bug

Brown Recluse
A shy, venomous brown spider of the south-central United States, known for six eyes in three pairs and a violin-shaped mark, whose bite can occasionally cause a slow-healing skin wound.
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.

Cigarette Beetle
A tiny, humpbacked, reddish-brown beetle that infests a wide range of dried stored goods, from spices and pet food to tobacco, tunneling through the product as a larva and flying toward light as an adult.
Cluster Fly
A sluggish, slightly oversized relative of the house fly whose larvae are parasites of earthworms outdoors, and whose adults pile into attics and wall voids of homes in fall to wait out the winter.
Drugstore Beetle
A tiny, humpbacked reddish-brown beetle that infests stored dry foods, spices, and even non-food goods, with larvae tunneling through the substrate to feed on almost anything dry in a pantry, kitchen, or warehouse.
Eastern Carpenter Bee
A large, shiny-backed native bee that chews round tunnels into bare wood to raise its young, often nesting in decks, eaves, and trim while doubling as an important pollinator.
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.
Fruit Fly
A tiny tan-to-brown fly with red eyes that breeds in overripe, fermenting, or damaged fruit and the moist residue in drains, found around kitchen counters and trash.
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 Cricket
A light yellowish-brown cricket with three dark bands across its head that lives outdoors in warm weather and moves into buildings when it turns cool, best known for the male's chirping and for being raised as fishing bait and pet food.
House Fly
A gray, four-striped filth fly that breeds in manure, garbage, and decaying matter and contaminates food and surfaces by carrying germs on its body and in its saliva and droppings.

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.
Red Flour Beetle
A tiny, shiny reddish-brown beetle that infests flour, cereal, and other dried, finely ground foods in pantries, mills, and warehouses, contaminating far more than it eats.
Red Imported Fire Ant
An aggressive, stinging, reddish-brown ant from South America that builds dome-shaped soil mounds across the southern U.S. and swarms to sting when its nest is disturbed.
