Stop Overwintering Spiders & Cluster Flies
Closing up your Lake Erie or Lake Ontario cottage for the winter? Don't let spiders, cluster flies, and overwintering insects take over while you're away. Follow our essential fall cottage closing checklist to ensure a clean, pest-free return in spring.
When you shut off heat and water in October, spiders, cluster flies, and boxelder bugs look for dark, undisturbed winter harborage. Female spiders lay insulated egg sacs inside soffits and window framing, which hatch into thousands of spiderlings by May. Proper fall closing prevents next spring's infestations before they begin.
A professional late-season exterior application around cottage foundations, crawlspaces, and eave peaks creates an active chemical barrier that stops cluster flies, Asian lady beetles, and female spiders from establishing winter nesting sites.
