Overwintering Pests

As the nights and days turn cooler, outside insects such as spiders, the Asian lady beetle, brown marmorated stink bug, boxelder bug, elm leaf beetle, earwigs, millipedes, etc. begin to enter buildings with the intent of finding a sheltered place to spend the winter.


When fall invaders get inside, some of them will die fairly soon due to drier indoor air, but others will end up in the attic, behind baseboards, or in wall voids. Then the heat of your house or an occasional warm day in the winter may bring them out into the open where they may be seen crawling along baseboards or up walls.


How to prevent overwintering of pests

Here are some tips on how to prevent overwintering of pests in your home. As you are doing your fall yard work, just take a few minutes to check out the perimeter of your home's foundation and address these issues.


  • Caulk cracks around doors and basement or ground floor windows.
  • Make sure window and door screens fit securely and screen outside vents.
  • Install threshold sweeps and weather stripping on ground level doors, including garage doors.
  • Move woodpiles, compost piles, piles of leaves or grass clippings, or stacked boards or stones away from the foundation.
  • Pull mulch away from foundation walls.
  • Remove grass, weeds, and ground cover plants that touch foundation walls.
  • Drain standing water around the foundation.
  • Trim any shrubs or tree branches that touch the roof or sides of the structure.

If you're still concerned, we can do an exterior perimeter spray around your foundation to prevent the entry of overwintering pests.
