Insects Are Getting Ready to Move Inside!

Fall is around the corner and will be here before you know it and this is the time when people will start noticing that various insects are getting into their homes. We call these pests “fall invaders” or “ occasional invaders” or just simply “ overwintering pests”. When the weather gets cooler and the insects outside food source begin to disappear, it’s time for them to come inside to spend the winter.

As part of their natural cycle, many insects die in the fall, but for others, the adult insect is destined to spend the winter in hiding and mate and lay eggs in the spring. Insects look for places that are protected from the elements such as under tree bark, rotting logs, under stones, in mulch or in firewood piles in the winter. However, if there’s a house or building nearby, some insects are attracted by the structure and it’s warmth and will look for ways to get inside.

Most of the insects that invade homes in large numbers are those that are associated with their surroundings. If you live near orchards or fields you may be more likely to have brown marmorated stink bugs or Asian lady beetles. If you live near certain trees you may see boxelder bugs or western conifer seed bugs. Some of the other types of insects you may see as the weather starts to cool are camel crickets, cluster flies and wasp queens. Once inside, the insects usually hide in the attic or in wall voids and may not be seen until warm days in early spring when it is time to go outside.

The best ways to keep these pests out of your home this fall is to have an exterior pesticide treatment around your home's foundation. This should be done soon before pests start to move in. Pest proofing your home by caulking cracks and gaps, screening vents, repairing soffits, adding door thresholds and sealing any openings where insects can enter.

Here are a few more tips for things to do on the outside of your home:

  • Move woodpiles, compost piles, piles of leaves or grass clippings, stacked boards or stones away from the foundation.
  • Pull mulch away from the foundation wall.
  • Remove grass, weeds and ground cover plants that touch the foundation walls.
  • Drain standing water around the foundation
  • Reduce outside lights, especially around doorways as many pests are attracted to lights.
  • Ventilate basements and crawlspaces to reduce moisture levels.
  • Trim any shrubs or tree branches that touch the roof or sides of the house.
