Why Spiders Are More Active in Boise During Fall
When temperatures drop in Boise, spiders seek warmth and shelter. That often means your home becomes the perfect hiding place. Fall is also when many spider species become more active due to mating cycles. You might not have noticed them before, but now they’re out in the open.
Spiders prefer undisturbed areas like garages, crawlspaces, basements, and storage rooms, which are common in Idaho homes. If your home has gaps or entry points, even small ones, it becomes easy for spiders to get inside.
Our Healthy Home Plan includes quarterly treatments for common pests like spiders, ants, and rodents. It’s designed to protect Boise homes all year long. Contact us to ask about setting up a plan that fits your home and schedule.

Common Spiders Found in Boise Homes
Several types of spiders are common in the Boise area:
- House Spiders: Often seen near ceilings, in closets, or behind furniture. Harmless but unsettling.
- Hobo Spiders: Sometimes mistaken for brown recluses; can bite if provoked.
- Wolf Spiders: Large, fast-moving spiders that don’t build webs. More intimidating than dangerous.
- Black Widows: Less common, but notable. They prefer dark, quiet areas like sheds or garages.
While bites are rare, it’s still important to understand symptoms and when to seek help. You can find trusted first aid guidance from the CDC on venomous spiders. Understanding which spiders are in your home helps determine the best treatment approach. Most aren’t dangerous, but their presence often signals other pest problems.
Where Spiders Hide in Your Home
Spiders tend to stay in quiet, undisturbed spaces where prey is present. In Boise homes, that includes:
- Ceiling corners and along baseboards
- Behind stored boxes or furniture
- Closets, attics, and crawlspaces
- Laundry rooms, bathrooms, and basements (due to moisture)
- Around vents, entryways, and windows
Why Spider Activity Could Mean You Have Other Pests
Seeing more spiders in your home often indicates that other pests are present. Spiders eat insects like flies, beetles, and ants. If your home is attracting prey, spiders won’t be far behind.
For complete results, spider control should go hand-in-hand with broader pest solutions. This is why Stonewood Pest offers ant and spider control as part of a complete pest management strategy.

Tips for Preventing Spiders This Season
You can reduce spider activity in your home with a few simple changes:
- Seal up gaps around doors, windows, and vents
- Reduce clutter, especially in storage areas
- Keep basements and bathrooms dry with dehumidifiers
- Remove visible webs regularly
- Turn off unnecessary exterior lights at night
- Trim bushes and trees away from your home’s siding and roof
Consistent home maintenance helps prevent not just spiders but many common fall pests in Boise.
When You Need Professional Spider Control
DIY steps are helpful, but sometimes they aren’t enough. Consider professional spider control if:
- You continue seeing spiders after taking preventive steps
- Spiders are appearing in bedrooms or bathrooms
