As the leaves start to fall and the temperatures drop, many St. Louis homeowners are busy preparing for winter — cleaning gutters, raking leaves, and stacking firewood. But what many don’t realize is that these same fall chores can make the difference between a pest-free home and a surprise infestation this winter.
Here’s how a few simple fall cleanups can keep unwanted guests — like mice, spiders, and ants — from moving in with you.
🧹 1. Rake Up Leaves and Yard Debris
Leaf piles aren’t just messy — they’re a cozy hideout for pests.
Ants, spiders, centipedes, and even rodents love the warmth and moisture that build up under layers of leaves and mulch.
Make sure to:
-
Rake leaves away from your foundation and porch
-
Bag or mulch them instead of piling them near the home
-
Keep garden beds clear of excess debris
A tidy yard doesn’t just look good — it takes away hiding spots for pests that could later find their way indoors.
💧 2. Clean Out Your Gutters
Clogged gutters create standing water, which attracts mosquitoes and can lead to water damage — both of which invite more pests.
When gutters overflow, moisture can seep into wood and insulation, creating the perfect breeding ground for termites and carpenter ants.
Clean gutters at least twice a year (spring and fall), and make sure downspouts direct water away from your foundation.
🔥 3. Store Firewood the Right Way
There’s nothing like a warm fire on a chilly St. Louis evening — but firewood can also be a highway for ants, beetles, and rodents.
Keep woodpiles:
-
At least 20 feet away from your house
-
Stacked off the ground on a rack or platform
-
Covered on top, but with sides open for airflow
Only bring in small amounts of wood at a time, and inspect logs before carrying them inside.
🏠 4. Seal Up Entry Points
Even the smallest gaps can let pests sneak inside to escape the cold.
Walk around your home and check for cracks near:
-
Windows and doors
-
Dryer vents and utility lines
-
Gaps under garage doors
Caulk, steel wool, or weather stripping can block common entryways — and prevent a mouse problem before it starts.
🌆 5. Local Tip: Fall Pests in St. Louis
Here in St. Louis, we see an uptick in calls every fall for:
