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.
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.
