Squirrel removal in Boulder, CO is the trapping and exclusion of fox squirrels, gray squirrels, and ground squirrels from attics, walls, soffits, and crawl spaces. In Boulder County, squirrels are non-protected species under Colorado Parks and Wildlife regulations, so a wider range of control methods is permitted than for raccoons or bats.
Squirrels are the most under-estimated wildlife problem in Boulder County. They're small enough that homeowners assume they'll leave on their own — but they nest, chew electrical wiring, and create entry points that larger animals (raccoons, birds) then use. Boulder's mature tree canopy in older neighborhoods like Mapleton Hill and Newlands creates ideal conditions year-round, and ground squirrels in foothills properties are a separate problem entirely.
Every squirrel removal job in Boulder County follows the same steps. The order doesn't change — what changes is the timing, depending on the species, season, and how active the situation is.
Fox squirrels, gray squirrels, and ground squirrels each require different control approaches. We identify the species, find entry points (often gnawed openings in soffits or roof edges), and check for active nests.
For attic infestations we typically use one-way exclusion doors on the main entry point — squirrels leave to forage and can't return. Active trapping is used when one-way doors aren't viable.
We monitor entry points for 7–10 days to confirm all squirrels have exited before any sealing work begins. Sealing a squirrel inside almost always results in chewed drywall as it tries to escape.
All entry points get sealed with heavy-gauge metal mesh and metal flashing where applicable — squirrels chew through wood, foam, and standard caulk easily.
Where overhanging branches give squirrels roof access, we recommend specific trimming (we don't do the trimming ourselves but provide a marked diagram for your arborist).
Most squirrel removal jobs in Boulder County fall in the $325–$575 range, including inspection, one-way exclusion, and sealing of the primary entry point. Larger homes with multiple entry points or longer monitoring windows can reach $600–$800.
Yes — squirrel-caused fires are a documented and significant risk. Squirrels gnaw constantly to keep their incisors at the right length, and unprotected wire insulation in attics is one of the materials they target. This is the single most urgent reason not to leave a squirrel infestation untreated.
Ground squirrels (often called "chiselers" in Colorado) are a different control problem — burrow networks under foundations, decks, and outbuildings. We handle these separately with targeted burrow exclusion. Pricing typically runs $250–$500 depending on the number of active burrows.
From first inspection to fully sealed entry points, most squirrel jobs in Boulder County take 10–14 days. The bulk of that is the monitoring window after one-way doors are installed — we won't seal openings until we've confirmed vacancy.
