How Denver's Seasons Shape Pest Problems—And What to Expect Year-Round

Winter: Rodents Head Indoors

As cold weather sets in, mice and rats start sneaking into homes in search of food and warmth. Older homes with basements, garages, or crawl spaces are especially prone to invasion. You might not spot them right away, but signs like droppings, scratching sounds, and chewed materials are hard to miss. Preventing winter rodent problems in Denver means more than just placing traps—it means sealing up the entire structure.

Spring: Ants and Occasional Invaders Arrive, Termites Start Swarming

As the ground thaws, ants become highly active—especially odorous house ants and pavement ants. You might first see them trailing along baseboards or kitchen counters. Spring is also when boxelder bugs, millipedes, and earwigs begin showing up inside as they move between outdoor hiding spots and indoor warmth. Early treatment helps stop these spring pests before they multiply. Subterranean termites—the most common type in Colorado—tend to swarm in the spring and early summer, especially after rain or when soil temperatures rise. 

Summer: Peak Season for Pest Activity

Summer is hands-down the busiest season for pest problems in Denver. Ant colonies expand rapidly, mosquitoes emerge near irrigated lawns and standing water, and spiders follow the food source. Wasps and hornets grow bolder and more territorial as their nests grow larger—often building them in eaves, deck railings, or play structures. If your backyard is starting to feel less inviting, you’re not alone.

Fall: Swarming, Stinging, and Sneaking In

Late summer into early fall brings peak wasp aggression as colonies become more defensive. This is also when pests like spiders and rodents start preparing to move indoors. Occasional invaders such as boxelder bugs and stink bugs often congregate on sunny exterior walls before slipping inside through gaps and cracks.

Year-Round: Spiders and Urban Wildlife

In Denver neighborhoods near open space or wooded areas, you’ll find year-round pressures from pests like wolf spiders, black widows, squirrels, and raccoons. They may be less visible in some months, but they don’t take the year off—and they’ll use any opportunity to get into garages, attics, or under decks.

Denver’s pest problems don’t follow a national template—they follow the local climate. Whether you’re battling ants in spring, wasps in late summer, or mice in the dead of winter, EnviroPest brings decades of Colorado-based insight to every job. We know what’s coming, and we know how to stop it.
