As the weather cools down, your warm home becomes a prime target for pests looking to escape the chill.

From mice to insects, these unwanted guests are eager to sneak in—but with the right prevention steps, you can stop them in their tracks.

Read on and learn how to seal up your home and keep critters out this fall!

Fall Pest Prevention

As the temperature drops, your home becomes prime real estate for pests looking to escape the cold. Mice, rats, spiders, and stink bugs aren’t just looking for a cozy spot—they’re aiming to crash at your place. But don’t worry, you don’t have to let these freeloaders settle in. With a few simple steps, you can keep these unwanted guests out and your home pest-free.

Seal the Entry Points

Pests are crafty little creatures. Mice can squeeze through holes the size of a dime! Spiders, bugs, and other critters can get in through even smaller gaps. The first step is sealing up all the possible ways they can sneak in.

Here’s a quick list of areas to check:

  • Foundation cracks and gaps around utility lines

  • Doors and windows—especially if the weather stripping is shot

  • Roof vents and chimney caps

  • Anywhere pipes enter your walls

  • Garage door gaps

Walk the perimeter of your home armed with a tube of silicone caulk and a roll of steel wool. Seal up those small gaps with the caulk and stuff the steel wool into any small holes (rodents hate chewing through it). If you come across larger gaps, use expandable foam to block them off. And don’t forget to check your roof—damaged shingles or loose flashing are basically a “Welcome” sign for pests looking to settle into your attic.

Clear the Perimeter

Creating a “no pest zone” around the outside of your home is a must. If your yard looks like a critter buffet or a great place for them to nest, they’ll be lining up to get in.

Here’s what to do:

  • Move woodpiles at least 20 feet away from your house. Critters love hiding in woodpiles.

  • Trim tree branches that touch or hang over your roof—those are pest highways.

  • Cut back shrubs from your walls to keep bugs from using them as a shortcut.

  • Pick up fallen fruit, nuts, and seeds—they’re tasty snacks for rodents.

  • Store outdoor pet food in sealed containers to avoid turning your yard into a pest picnic.

  • Tightly seal trash bins and keep them away from the house.

If you remove these pest attractions, they’ll be less likely to hang around your yard, and that means they’re less likely to try sneaking inside.

Get Rid of Moisture Sources

Pests love moisture. Damp areas are like a vacation resort for bugs, so getting rid of excess moisture is key.

Here’s how:

  • Fix any leaky outdoor faucets or pipes—even a slow drip can attract pests.

  • Clean your gutters and make sure they’re draining properly. Clogged gutters can cause water buildup, which draws pests.

  • Make sure your soil is graded away from your foundation so water doesn’t pool up near your house.

  • Check your basement or crawl space for dampness and install a dehumidifier if needed.

  • Keep mulch thin near your foundation to prevent moisture buildup, which attracts bugs like termites.

Lock Down the Food Sources

If there’s food around, pests will come. Make it hard for them to find a meal, and they’ll move on.

Here’s how to secure the pantry:

  • Store food in airtight containers. Those cardboard cereal boxes and open bags of flour are an open invitation to mice.

  • Clean up crumbs and spills right away, especially in the kitchen. Even a few crumbs can be enough to attract pests.

  • Keep pet food in sealed containers, and don’t leave it sitting out overnight.

  • Take out the trash regularly—and make sure the garbage can has a tight-fitting lid.

  • Fix any leaky under-sink plumbing so water and dampness don’t attract bugs.

Focus on Key Areas

Some parts of the house are pest magnets. Give them extra attention:

  • In the kitchen, check for gaps where pipes enter under the sink, and clean behind appliances regularly.

  • In the basement, install door sweeps on exterior doors, check window wells for drainage, and keep items stored in plastic bins instead of cardboard.

  • In the attic, install mesh screens over vents, inspect roof edges for gaps, and keep insulation clear of soffit vents.

Stay Vigilant: Monitor and Maintain

You’ve done all the hard work, but that doesn’t mean you can relax just yet. Regularly check your home for signs of pests and take action right away if you see any red flags.

  • Check traps and monitoring stations monthly.

  • Keep an eye out for droppings or gnaw marks in storage areas.

  • Listen for scratching noises in the walls or ceiling.

  • If you see any new entry points, seal them up ASAP.

Know When to Call the Pros

Sometimes, DIY pest control just isn’t enough. If you’ve already got an infestation or live in an area with persistent pest problems, it might be time to bring in the big guns. A professional can help with more serious situations or provide preventive treatments if you want to be extra cautious.

Prevention is way easier—and cheaper—than dealing with a full-blown pest problem. By taking these steps now, you’ll make sure your home stays pest-free all fall and winter long. So grab that caulk, check those cracks, and keep the critters out where they belong!

Q&A: Should I rake my leaves or leave them till spring?

For a healthy lawn, remove leaves when they fully cover and mat down the grass, but consider mulching lighter leaf coverage with your mower - it acts as free fertilizer.

While clearing main lawn areas is important, you can leave leaves in garden beds and natural areas where they benefit wildlife and enrich soil.

The key is balance: don't let leaves smother your grass, but also don't feel you need to remove every single leaf.
