When snow dusts the peaks and temperatures in Boise dip, many homeowners breathe easy—pests must be gone, right? Not quite. Winter only changes tactics, not their determination. For residents across Treasure Valley, winter is prime time for common pests like rodents, spiders, ants, and cockroaches to move inside seeking warmth, food, and shelter. At Boise Pest Pros, we believe year-round pest control isn’t optional—it’s essential.

Why Pests Don’t Disappear in Winter (They Just Move In)
-
Rodents on the Move
Mice and rats don’t hibernate—they redecorate your attic. When temperatures drop, they look for gaps around doors, windows, and foundations. Inside, there’s insulation for nesting, wiring to chew (because why not?), and your pantry to raid. Evidence from Idaho’s winter pest studies shows rodents are active, not dormant. -
Spiders & Insects Seeking Refuge
Spiders often follow their prey indoors or seek out dark, undisturbed areas like basements, crawlspaces, behind furniture, or in attics. Ants, cockroaches, and other moisture-loving insects likewise creep in where water sources or humidity linger. Ants and cockroaches both show up in winter when outdoor conditions are harsh. These are some of the most common pests Boise homeowners face year-round, each capable of turning cozy spaces into their own hideouts. -
Damage & Health Risks Don’t Wait
Unchecked pests in winter can cause property damage (chewed insulation or wiring, structural damage from rodents, etc.), contaminate food, trigger allergies, and carry diseases. By the time you notice them, it’s like discovering uninvited houseguests who’ve already unpacked their bags. Prevention is far cheaper and easier than cleanup and repair.

Winter Pest Control Tips from Boise Pest Pros
Here are proven methods we use (and recommend) to keep your home pest-free during Boise’s cold months:
-
Seal Entry Points
Patch cracks in foundation, gaps around windows/doors, openings around vents/pipes. Weather-stripping is your friend. -
Maintain Clean & Dry Spaces
Remove clutter. Clean up crumbs or food spills quickly. Fix leaky pipes. Make sure attics and basements stay dry—moisture attracts insects and gives rodents a reason to stay. -
Regular Inspection & Monitoring
Spotting signs early (droppings, chewed wood, small holes, nests) gives you the upper hand. Boise Pest Pros inspections can catch weak points before infestations begin. -
Use Physical Deterrents & Barriers
Screens, door sweeps, mesh over vents, sealing gaps, blocking access under doors. -
Professional Treatments & Preventive Services
Even in winter, treatments like targeted baiting for rodents, insect barrier treatments in key entry points, attic and crawlspace treatments help. Also, safe, pet- and family-friendly methods to ensure peace of mind.
