As autumn settles into the Denver Metro Area, the crisp air and changing leaves signal a shift in pest behavior. While you may be prepping your home for colder weather, so are pests, just in their own way. Rodents, spiders, cockroaches, and even stink bugs begin their migration indoors, looking for warmth and shelter. That’s why early fall is the best time to prepare your home with a strategic pest prevention plan.
The seasonal transition from summer to fall may seem subtle, but for pests, it’s a survival trigger. As nighttime temperatures drop, insects and rodents begin seeking stable indoor environments. Denver homes with cracks, gaps, or poor sealing become easy entry points—and once they’re inside, pests are hard to evict.
Pests don’t just cause discomfort. Rodents can chew through insulation and wires, increasing the risk of fire. Cockroaches can contaminate surfaces, and spiders may set up webs in dark, damp corners. A small oversight in fall could mean a full-blown infestation by winter.
