Trust Mosquito Squad for Fall-to-Winter Pest Control in Fort Collins & Boulder

Posted by Mosquito Squad

December 19, 2025

The changing seasons mean changes in pest behaviors – but that doesn’t mean it’s time to take a break from pest control. In fact, hundreds of bug species spend the cold months in residential homes and other buildings, where they wreak plenty of havoc. Take back control with help from Mosquito Squad.

Fort Collins Homes Face Unique Pest Challenges as the Seasons Shift

When the golden leaves start to drop and the mountain air gets brisker, pests across Fort Collins and Boulder start scouting for winter shelter. Unfortunately, that can often result in bugs mistaking your home for their winter vacation spot. Each fall and winter, pests like rodents, spiders, and boxelder bugs prefer to move indoors. At Mosquito Squad, our seasonal pest control services are designed to help you maintain a barrier between your home and the pests trying to breach it.

Rodent Control in Fort Collins & Boulder

Falling temperatures signal to rodents like mice and rats that it’s time to find a place to spend the winter. Because of the abundant warmth and food, these places tend to be homes and other buildings. Rodents usually slip inside through small openings you might not even notice, like crawl spaces to attic vents. Once inside, rodents can cause significant property damage and contribute to indoor air quality issues because of their droppings and dander.

Our rodent control in Fort Collins and Boulder includes a thorough inspection of entry points as well as treatments that effectively manage rodent populations. With professional help from Mosquito Squad, you can take back control of your home and avoid costly repairs or health hazards down the line.

Boxelder Bug Control Before They Overstay Their Welcome

Boxelder bugs may not cause structural damage or transmit disease, but that doesn’t stop them from being one of the most frustrating fall intruders in Northern Colorado. These bugs congregate in massive numbers on the sunny sides of homes and sneak indoors to overwinter in walls, basements, and window frames. We offer boxelder bug control treatments that target cracks and crevices around windows, doors, and siding before the bugs get cozy inside.

Spiders Don’t Hibernate

Many people think pests go dormant in winter, but some pests, like spiders, are actually quite active throughout the fall and winter. That’s a problem because venomous species such as black widows, while rare, are a known concern here, and even non-threatening spiders can create messy webs and unpleasant encounters. You may also see stink bugs, Asian beetles, or ants trying to take refuge indoors.

Our pest professionals use spider control treatments that help minimize the chances of these pests becoming long-term guests so that your home stays more comfortable throughout the season.

Why Seasonal Pest Services Make Sense in Northern Colorado

Fluctuating daytime temperatures and sudden cold snaps are a Fort Collins and Boulder norm, which makes it easy for pests to be active one day and burrowed in the next. This unpredictability is exactly why fall pest control in Fort Collins and Boulder is so important. The best time to act is before pests get inside.
