Identification guides, threat levels, warning signs, and seasonal activity for the most common pests in Sun City and the greater Phoenix metro — from a veteran-owned team that deals with them every day.
Centruroides sculpturatus
Arizona Bark Scorpion
The most venomous scorpion in North America and the most dangerous pest in Arizona. Bark scorpions are climbers — unlike most scorpions, they can scale walls, ceilings, and even hang upside down. They glow bright blue-green under UV (black) light, which is why many Sun City residents do nighttime sweeps with UV flashlights.
Heterotermes aureus
Desert Subterranean Termite
Arizona's most destructive termite species. Desert subterranean termites build mud tubes from the soil to reach wood above ground, allowing them to attack structures without ever being exposed to open air. A single colony can contain hundreds of thousands of workers consuming wood 24 hours a day. Most homeowners don't discover an infestation until significant structural damage has already occurred.
Periplaneta americana
American Cockroach
Despite the name, the American cockroach is originally from Africa and thrives in Arizona's warm climate. Also called "palmetto bugs" or "water bugs," these large roaches prefer sewers, drains, and damp areas. They're strong fliers and can enter homes through gaps around pipes, drains, and utility penetrations. They carry bacteria, trigger asthma, and contaminate food surfaces.
Solenopsis invicta
Red Imported Fire Ant
Fire ants are aggressive, sting repeatedly, and their mounds can appear overnight. Unlike most ants that bite, fire ants sting — injecting venom that causes an intense burning sensation followed by white pustules. They're a serious threat to pets, children, and anyone with venom allergies. Fire ant mounds are common in lawns, parks, and along irrigation lines throughout the Phoenix metro.
Cimex lectularius
Common Bed Bug
Bed bugs are expert hitchhikers — they travel on luggage, used furniture, clothing, and even library books. They don't transmit disease, but their bites cause intense itching, sleep disruption, and significant psychological distress. A single pregnant female can establish a full infestation in weeks. They hide in mattress seams, box springs, headboards, electrical outlets, and baseboards — anywhere within 8 feet of a sleeping host.
Rattus rattus
Roof Rat
Roof rats are the dominant rat species in the Phoenix metro. Agile climbers, they enter homes through rooflines, attic vents, and gaps around utility lines. They nest in attics, palm trees, and dense shrubs. Roof rats gnaw through electrical wiring (a leading cause of house fires), contaminate food, and carry diseases including leptospirosis and salmonella. A pair can produce up to 40 offspring per year.
Apis mellifera scutellata hybrid
Africanized Honey Bee
Africanized honey bees — commonly called "killer bees" — look identical to European honey bees but are dramatically more defensive. They respond to perceived threats in far greater numbers, pursue threats for up to a quarter mile, and remain agitated for hours after disturbance. Arizona is prime Africanized bee territory. They nest in wall voids, water meter boxes, irrigation valve boxes, and any enclosed cavity. Never approach a swarm or hive without professional equipment.
Latrodectus hesperus
Western Black Widow
The western black widow is the most medically significant spider in Arizona. Females are the dangerous ones — males rarely bite. Black widows prefer dark, undisturbed areas: garage corners, under patio furniture, inside block walls, and in wood piles. Their venom is a neurotoxin that causes severe muscle cramps, pain, and in rare cases can be life-threatening to children and the elderly. They're not aggressive but will bite when accidentally contacted.
Neotoma albigula
White-Throated Woodrat (Pack Rat)
Pack rats are native Arizona desert rodents that build large, elaborate nests (middens) from sticks, cactus, and debris — often under vehicles, in engine compartments, or inside outdoor equipment. They chew through wiring, hoses, and insulation. A single pack rat can cause thousands of dollars in vehicle damage. They're attracted to citrus trees, bird feeders, and cluttered storage areas.
Thomomys bottae
Valley Pocket Gopher
Pocket gophers are burrowing rodents that destroy lawns, gardens, and irrigation systems from underground. They feed on plant roots and bulbs, killing vegetation from below. Their tunnel systems can undermine driveways, sidewalks, and foundations over time. Unlike moles, gophers create fan-shaped mounds of loose soil with a plugged entry hole off to the side.
Polistes exclamans / Polistes apachus
Paper Wasp
Paper wasps are common throughout Arizona and build open, umbrella-shaped nests from chewed wood fiber. They're less aggressive than yellow jackets but will sting repeatedly when their nest is threatened. Nests appear under eaves, in attic vents, behind shutters, and in dense shrubs. Multiple stings can trigger severe allergic reactions in sensitive individuals.
Pogonomyrmex barbatus
Red Harvester Ant
Red harvester ants are native to Arizona and create large, barren clearings around their mound entrances. They collect seeds and can strip vegetation from a significant area around their colony. Their sting is one of the most painful of any ant species — ranked near the top of the Schmidt Pain Index. They're common in desert landscaping, gravel yards, and along sidewalks.
