Exclusion is the right call when you have a repeat problem — droppings return every fall, you hear scratching in the same wall each November, or bait "worked" twice and then didn't. Trapping and monitoring alone fit a narrower case: one mouse that wandered in through an open garage door, a rental where you don't control repairs, or an active infestation that has to be knocked down before we start closing holes. The honest trade-off is time and money up front. Sealing a house takes hours of ladder work, crawling, and cutting metal, and it costs more than a handful of snap traps — but it removes the highway instead of thinning the traffic. We usually run trapping and sealing together: seal the openings, then keep traps in place until activity stops, so nothing gets closed in.
Longmont housing stock changes the job block by block. In <strong>Old Town Longmont</strong>, older foundations, stone or uneven crawlspace walls, coal-chute patches and original wood-framed crawl vents give mice several low, hidden options; those homes almost always need hardware cloth cut and fitted rather than a caulk gun. Alley-loaded garages around <strong>Prospect New Town</strong> are frequent first entries — the bottom corners of an overhead door leave a gap you can see daylight through, and the garage connects straight to the living space. Newer south-side builds in <strong>Clover Basin, Somerset Meadows, Fox Meadows and Rider's Ridge</strong> look tight but often have unsealed stucco weep screeds, loose vent flappers and open gaps where the A/C line set passes the wall. Homes backing irrigated greenbelts and open ground near <strong>Ute Creek, Lake Park, Southmoor Park and Mill Village</strong> sit next to good rodent habitat — the St. Vrain Greenway corridor, Left Hand Creek, ditch banks, and the field edges toward Union Reservoir, Sandstone Ranch and out into western Weld County. When canyon and plains nights cool off in September and October, that outside population starts testing walls, and the houses with open penetrations are the ones that get company.
A fair question is whether this is a $30 hardware-store fix. Some of it can be — a good door sweep is cheap and worth installing. What fails is expanding foam and steel wool used alone: mice chew straight through cured foam, and steel wool rusts and pulls out. What also fails is sealing the three gaps you can reach and missing the six you can't see from the ground. The value we sell is the finding, then the correct material at each opening. Sealing is also mechanical, not chemical, which matters if you have a dog in the yard or raised vegetable beds — the exclusion portion of the work introduces no product into your soil or air. Where trapping or a rodenticide station is genuinely needed, we tell you exactly what we're using, where it goes, and how it's secured.
Every job ends with the Entry-Point Report so you own the documentation: photos of each gap, what we installed there, and any repairs outside pest-control scope (rotted trim, a failing garage door panel, a crushed crawl vent) that a handyman or roofer should handle. Exclusion is one part of our broader <a href="/">Longmont pest control service</a>, and it's the part that decides whether the mice come back next fall. Call (303) 531-5636 to get on the schedule.
