As summer fades and the Pacific Northwest’s rainy season approaches, our yards and homes shift gears. Leaves fall, temperatures drop, and many pests begin seeking warm, dry shelter — often inside our homes. A few proactive steps this time of year can go a long way toward keeping unwanted guests like ants, rodents, and moisture-loving insects outdoors where they belong.

Key Takeaways

  • Keep leaves and yard debris away from your home’s foundation.

  • Store summer items like furniture, toys, and building materials properly.

  • Maintain clean, functional gutters and downspouts.

  • Manage rainwater and fix leaks to prevent moisture issues.

  • Trim vegetation to reduce pest bridges and moisture damage.

Don’t Let Leaves Build Up Against the Foundation

Leaf piles and organic debris can trap moisture against your siding and create ideal hiding spots for ants, spiders, and rodents. When you’re raking or using a leaf blower, avoid pushing leaves up against the foundation, crawlspace vents, or basement windows. Instead, collect and compost them, or use them in garden beds away from the home’s perimeter.

In addition to attracting pests, leaf buildup interferes with professional pest control treatments. When leaves, mulch, or soil are packed against the foundation, technicians can’t properly treat the base of the structure — the most important zone for keeping pests out. Even if a treatment is applied, organic debris can absorb the product, reducing its effectiveness. A clear, exposed foundation line ensures superior protection and longer-lasting results from your pest control service.

A clean, dry foundation perimeter helps discourage pest activity, protects siding, and allows treatments to reach where they’re needed most.

Store Summer Furniture, Toys, and Tools

Fall is the time to tidy up your yard before the wet weather sets in. Patio furniture, garden tools, kids’ toys, and leftover building materials all make convenient shelters for overwintering insects and rodents.

  • Store items in sealed sheds or garages when possible.

  • Inspect and clean before storing to avoid bringing pests inside.

  • Eliminate clutter that could harbor nesting materials or moisture.

Keeping the yard clear not only improves appearance — it removes the conditions pests depend on to survive winter.

Rainwater Management and Gutter Maintenance

Heavy fall rains can quickly reveal clogged gutters, leaking seams, and downspouts that drain too close to the foundation. Overflowing gutters allow water to spill down siding, saturate soil, and eventually lead to wood rot and pest activity.

Take time to:
  • Clean gutters and downspouts to keep water flowing freely.

  • Repair leaks or misaligned sections to prevent overflow.

  • Ensure proper drainage — downspouts should discharge at least 3–5 feet from the home, or at least drain away from the foundation.

  • Inspect splash blocks or drain extensions for clogs or erosion.

By keeping water under control, you reduce both pest pressure and structural moisture issues.

Keep Vegetation Trimmed and Away from the House

Overgrown shrubs and climbing plants can create bridges for ants and rodents while also trapping moisture against siding. When rain hits untrimmed vegetation, the splashback can lead to mildew, paint damage, and eventually rot.

  • Trim bushes, tree limbs, and ground cover at least 12–18 inches away from the home.

  • Avoid direct contact with the roofline or eaves.

  • Remove ivy or vines that grow directly on walls — they hold moisture and provide pest harborage.

Proper trimming not only improves airflow and drying time but helps keep the building envelope pest-free.

Final Thoughts

A little fall maintenance can make a huge difference in preventing pest problems through winter. By managing moisture, keeping the perimeter clear, and reducing clutter, you’re not just protecting your home from insects and rodents — you’re also preserving the integrity of your structure and siding.
