Gilbert is one of the fastest-growing cities in Arizona, and its location at the edge of the Sonoran Desert shapes the pest environment that homeowners deal with year-round. The species below are the most common pest concerns we encounter when servicing Gilbert homes, and each one requires a different approach to control effectively.
Bark Scorpions
The bark scorpion is the pest that Gilbert homeowners ask about most, and it is the one that warrants the most serious attention. It is the most venomous scorpion species in the United States, it is an excellent climber, and it is common throughout Gilbert—in new master-planned communities as well as established neighborhoods. Bark scorpions are active year-round in the East Valley, with peak activity from April through October.
Scorpion encounters inside Gilbert homes most often occur in bedrooms, closets, and bathrooms—spaces where scorpions shelter during daylight hours after entering through gaps in the structure.
Roof Rats
Roof rats have become one of the most frequently reported pest problems in Gilbert over the past decade. Mature citrus trees, untrimmed palm trees, and the block wall networks that connect Gilbert’s neighborhoods give roof rats abundant food, nesting habitat, and travel routes. They access homes through roofline gaps and attic vents and cause structural damage through gnawing and contamination of attic insulation.
Signs of roof rat activity include nighttime scratching sounds from the attic, hollowed-out citrus fruit still on the tree, and droppings along block wall tops.
Ants
Argentine ants are the most commonly reported ant species in Gilbert homes. They form large supercolonies with multiple queens and are difficult to eliminate with surface sprays alone because treating visible trails does not reach the colony. Fire ants are also present in the East Valley and are a concern in yard areas and for homeowners with children and pets.
Black Widow Spiders
The western black widow is common in Gilbert and is found in garages, under outdoor furniture, in irrigation boxes, and along block wall bases throughout the city. Bites are medically significant and warrant immediate attention. Black widows are most active in spring and fall but are present year-round in protected outdoor spaces.
Cockroaches
American cockroaches and Turkestan cockroaches are the species most commonly encountered in Gilbert yards and structures. Both are associated with moisture and are found around irrigation systems, in utility areas, and in any ground-level space with consistent water access. German cockroaches, the smaller kitchen species, are less common but are the most serious infestation risk when present indoors.
Stinging Insects
Paper wasps are the most visible stinging insect in Gilbert yards, nesting under eaves, in door frames, and along exterior walls. Yellow jackets become the more serious concern in late summer when their ground nests reach peak size and the colony becomes highly defensive. Both species warrant professional treatment when nests are located near entry points or outdoor living areas.
Year-Round Protection in Gilbert
Gilbert’s climate does not produce a true pest off-season. Managing the range of species active in this area requires consistent, scheduled treatment rather than reactive calls when problems become visible.
