Ask A Pest Control Professional – #4

Why are my window sills covered with flies and other bugs in the Fall?

Every early to late fall insects as Spiders, Weevils, Cluster Flies, Lady bugs, Stink and True Bugs begin to seek out dry, protected overwintering harborage sites in order to increase their chances of survival. As outside temperatures decrease, our in home heat and lighting increase making it very attractive to shelter seeking critters.

Preventively inspect and pest proof your house from ground up especially South facing, warmest side of house: cracks, crevices, gaps around foundation, in siding, around windows, vents, flashing, screens and door seams and around utility lines. The key is to identify and control insects before they enter the structure.
