Winter in the Treasure Valley brings crisp air, snow-dusted landscapes, and unfortunately, an uptick in unwanted houseguests—pests seeking warmth and shelter. While some pests slow down during colder months, others become more active indoors. At Habitat Pest & Lawn, we help Boise homeowners keep their spaces pest-free all year long. Here’s what you need to know about winter pests and how to prevent them.
Common Winter Pests in the Treasure Valley
Rodents (Mice & Rats)
As temperatures drop, mice and rats look for warm places to nest—often inside homes, garages, and sheds. These pests can chew through insulation, wiring, and stored food, creating costly damage and potential health hazards.
Signs of Infestation:
- Droppings in pantries, along walls, or under sinks
- Scratching noises in walls or ceilings
- Chewed wires, food packaging, or insulation
Spiders
While many spiders remain outdoors, species like the hobo spider and black widow may seek refuge in basements, garages, or undisturbed corners of your home.
Signs of Infestation:
- Webs in corners, near windows, or in storage areas
- An increase in spider sightings indoors
Cockroaches
Cockroaches thrive in warm, humid environments and can sneak into homes through small cracks or hitchhike in grocery bags or boxes. Once inside, they multiply quickly.
Signs of Infestation:
- Droppings that look like coffee grounds
- Musty or oily odor in infested areas
- Shed skins or egg casings near food sources
Silverfish
These small, silvery insects are often found in bathrooms, basements, and other damp areas. They feed on paper, glue, and starchy materials, making books, wallpaper, and stored food susceptible.
Signs of Infestation:
- Small, irregular holes in paper or fabric
- Yellowish stains on clothing or books
- Quick-moving insects in dark, humid areas
How to Prevent Winter Pests
- Seal Entry Points
Inspect your home for gaps around windows, doors, pipes, and vents. Use weather stripping, caulk, and mesh screens to close potential entry points.
- Keep Food Stored Securely
Pests are always on the hunt for food. Store pantry items in airtight containers, wipe up crumbs immediately, and take out the trash regularly.
- Reduce Moisture
Many pests, including cockroaches and silverfish, thrive in humid environments. Fix leaks, use a dehumidifier in damp areas, and ensure proper ventilation in bathrooms and basements.
- Declutter & Deep Clean
Rodents and insects love hiding in cluttered spaces. Regularly clean out storage areas, vacuum behind appliances, and avoid stacking firewood directly against your home.
- Schedule a Professional Pest Inspection
Even the cleanest homes can become a target for winter pests. Habitat Pest & Lawn offers expert inspections and customized treatments to keep your home protected all season long.
