Spiders — year-round

Spiders are one of the most common pest problems in the Treasure Valley. While most species found in Idaho are harmless, a heavy infestation around windows, doorways, eaves, and basements is a sign that conditions around your home are attracting them.

Ants — spring to fall

Ants are a seasonal but persistent problem for Treasure Valley homes. What starts as a few in the kitchen can quickly become multiple trails throughout the home. Store-bought sprays often make the problem worse by scattering the colony — effective treatment targets the entry points and the source.

Wasps & Hornets — summer to fall

Wasps and hornets build nests in eaves, fences, decks, and ground-level areas around Treasure Valley homes. Unlike bees, wasps can sting repeatedly and become aggressive when disturbed. By late summer, colonies can reach several hundred.

Mice & Rodents — fall to winter

As temperatures drop in the fall, mice look for warm places to nest, and homes in the Treasure Valley are a common target. They can squeeze through gaps the size of a dime, contaminate food, and cause damage to insulation and wiring.

Box Elder Bugs — fall & spring

Box elder bugs cluster in large numbers on the sunny sides of homes in fall as they search for overwintering spots. They're harmless but can stain surfaces and are unpleasant in large numbers.

Beetles — varies by species

Several beetle species are common in Idaho, from carpet beetles that damage fabric and stored goods, to ground beetles that wander inside in search of food or shelter. Consistent perimeter treatment is the most effective way to keep them out.

Earwigs — spring to fall

Earwigs are one of the more alarming-looking pests homeowners find in the Treasure Valley, though despite the pinchers, they're not dangerous to people or pets. They thrive in moisture and are most often found around garden beds, under debris, and in basements or crawl spaces.

Crickets — summer to fall

Crickets are a common late-summer and fall nuisance in the Treasure Valley. Field crickets and house crickets are both common in the area, and both respond well to perimeter treatment.

Centipedes & Millipedes — spring to fall

House centipedes and millipedes are both common in Treasure Valley homes, particularly in basements, garages, and bathrooms. Centipedes are fast-moving predators that feed on other insects — their presence often signals a broader pest issue.
