Fall is almost here. That means Halloween, Thanksgiving, and the change of the leaves. But brightly colored leaves and tasty meals aren’t the only things that come with fall. Fall is when certain bugs and wildlife get the notion that living in your home might be better than living outside. Here are a few of the repeat offenders.


When temperatures drop, rodents get motivated to find a place to hide from the cold, and being rodents, they are equipped to chew their way in. If you want to keep these pests out, you’re going to have to make sure there are no soft or vulnerable areas on your exterior walls.

Exclusion Methods

  • Preventing water damage is the first step in preventing rodent infestations. Make sure your gutters are not blocked or broken. When water runs down the side of your home it will create the conditions for wood rot to begin.
  • If you have any rotted areas, use a caulking gun to fill those areas in. Don’t wait to get those places fixed “right,” because rodents will make quick work of expanding those holes.
  • Consider putting wire mesh in your downspouts to prevent rodents from climbing up and gaining access to your vulnerable roofline.


This is a robust insect species that can survive cold temperatures. But, given the option of being in the warmth of your home for the winter, they will take it. The difficulty with cockroaches is that they can climb walls and traverse ceilings. Cockroaches are not an easy critter to keep out.

Exclusion Methods

  • Make sure all your window and door screens are free of holes or slits.
  • Examine all your door sweeps and weather stripping to see that they make good contact all the way across.
  • Fill in any cracks on your basement walls.


These pests have natural antifreeze that helps them survive the winter; but, like those cockroaches, your home is a preferable choice to living in a cold hole. When they begin to search for a place to hide from the cold, make sure they aren’t already near your exterior walls. Don’t give spiders a reason to be near your walls and you will have less to worry about when fall comes. Spiders eat bugs. Fewer bugs around your home will result in fewer spiders.

Exclusion Methods

  • Cover your trash cans to reduce flies.
  • Replace exterior white lights with yellow insect-resistant lights. Flying insects are attracted to light.
  • Close the curtains at night, so that light does not draw insects in.
  • Keep plants and flowers at least 10 feet from your exterior walls.

These exclusion methods can help you resist fall pests. But the most effective way to keep fall pests completely out is by having your walls treated by a professional. If bugs don’t want to be on your exterior walls, they won’t be looking for a way in.
