Common Idaho Pests
Rodents (Mice & Rats)
Season: Fall through early spring (seeking warmth indoors)
Signs to watch for: Droppings, chewed wires, squeaking in walls, dead spots in insulation, chewed boxes.
Carpenter Ants
Season: Spring through fall (especially spring)
Signs to watch for: Large ants in kitchen, wood shavings near baseboards, hollow-sounding wood, rustling sounds inside walls.
Termites
Season: Year-round (more active in spring/early summer)
Signs to watch for: Mud tubes on foundation, wood damage, swarming insects in spring, hollow-sounding wood. Very destructive if untreated.
Wasps & Hornets
Season: Spring through fall
Signs to watch for: Nests under eaves, paper-like nests in trees, increased activity near garbage. Dangerous if you're allergic.
Spiders
Season: Year-round (more noticeable in fall)
Signs to watch for: Most spiders are harmless and eat other bugs. Only treat if excessive or if you have a dangerous species.
Prevention: Your First & Best Defense
Prevention costs nothing but saves thousands in treatment and damage repair. Start with these five steps:
✓ Seal All Entry Points
Caulk cracks, seal gaps around pipes, wires, and utility lines. Rodents fit through dime-sized holes. Check basement, attic, and around doors/windows.
✓ Remove Food Sources
Keep kitchen clean, don't leave pet food out overnight, store food in airtight containers, take garbage out regularly, clean up spills immediately.
✓ Eliminate Moisture
Fix leaky pipes, reduce humidity, ensure proper drainage around foundation. Pests need water just like we do. Dehumidifiers help in basements.
✓ Trim Vegetation
Cut tree branches away from house, remove dead trees and stumps, don't plant shrubs directly against foundation. Pests hide and travel through vegetation.
✓ Store Firewood Away
Keep woodpiles 20+ feet from house, stack off the ground on raised platforms, cover with tarps. Pests live in firewood and can migrate into your home.
