ProShield Pest SolutionsProShield Pest SolutionsExpect $250–$400 for a one-time general pest treatment in Longmont and $350–$750+ when mice are involved and entry points need sealing. ProShield prices off what the inspection finds — clay-soil foundation cracks and canyon-side rodent pressure change the number more than square footage does.

Typical Longmont pest control price ranges (ballparks — exact price confirmed on a free on-site inspection; $250 minimum service charge)
The minimum service charge for pest control in Longmont is <strong>$250</strong>, and no job is quoted below it. That figure covers the technician's drive, the inspection, the products, and the labor of treating both the inside and the exterior perimeter of a typical single-family home. A single ant trail and a whole-home general treatment often land in the same $250–$400 window, because the truck roll and the inspection are the bulk of the cost either way. Homeowners looking for a $30 hardware-store fix are better served by the hardware store; this is a done-for-you service with a technician on the ladder and in the crawlspace.
Mouse and rat work generally runs <strong>$350 to $750 or more</strong> in Longmont, versus $250–$400 for a general pest treatment. The difference is exclusion labor. Trapping removes the mice already inside; sealing the gaps stops the next ones. A mouse fits through an opening the width of a pencil, and the usual openings on Front Range homes are garage door corner gaps, dryer and utility line penetrations, crawlspace vent screens, and the seam where siding meets a settled foundation. Larger sealing scopes — several vents plus multiple penetrations — move into the $400–$1,200 range because materials and hours climb. Every rodent quote is built from a written Entry-Point Report, not a flat guess.
Recurring quarterly service in Longmont typically runs <strong>$250 to $350 per visit</strong>, or roughly $1,000 to $1,400 a year. One-time calls priced at $250–$400 each add up faster if a home has recurring pressure — greenbelt-adjacent lots, irrigated lawns, mature cottonwoods, or an unfinished basement. Quarterly timing exists because the pests are seasonal: spring ants, summer wasps on sun-baked south walls, fall mice and cluster flies, winter spiders indoors. Homes with a single isolated problem, like one wasp nest under a soffit, usually do not need a plan at all, and a technician will say so.
Phone estimates are ballparks; the exact price comes from the free on-site inspection. A technician needs to see the foundation line, the crawlspace or basement, the roofline, and the pest evidence itself before committing to a number. Droppings in a pantry can mean two mice in a garage or a colony behind a kitchen soffit, and those are different jobs at different prices. Pricing inputs include home square footage, foundation and crawlspace access, how many stories the exterior treatment covers, the pest species, and how much sealing work the entry points require. No page can quote a home it hasn't seen — anyone promising an exact price sight-unseen is guessing.
A recurring theme in r/pestcontrol threads, paraphrased: a retail spray or bait station appears to work, then the ants or mice are back in three to six weeks. The mechanism is consistent with the complaint. Contact sprays kill foragers, not the nest, and ant colonies simply route around a treated line. Rodent bait placed indoors without sealing the exterior gap just keeps feeding new arrivals from outside. A professional treatment at <strong>$250–$400</strong> pairs non-repellent or bait-based products with the physical exclusion step, which is the part a spray can never do. Product names, active ingredients, and re-entry intervals are stated out loud before any application, including around pets and vegetable beds.
Species drives price. Ants, spiders, and wasps sit in the <strong>$250–$400</strong> band because treatment is a single focused visit. Rodents cost more because of sealing labor. Voles and pocket gophers in irrigated Longmont lawns run $300–$600 and often need repeat visits, since new animals move in from adjacent turf. Bed bugs are the most expensive line item in the Front Range market — commonly $500–$1,200+ per affected room — because they require prep, thorough treatment, and follow-up. Getting the species identified correctly at the inspection is what keeps a homeowner from paying for the wrong treatment twice.
Longmont sits in Boulder County at the mouth of the St. Vrain and Left Hand Creek corridors, and that geography shows up on invoices. Homes near Left Hand Creek and the St. Vrain Greenway carry heavier rodent and spider pressure than inland lots, so exclusion scopes — and prices — trend toward the upper half of the $350–$750 rodent range. Old Town Longmont's pre-1940 housing stock brings stone and rubble foundations, original crawlspaces, and balloon-framed wall voids, which usually means more sealing hours than a 2005 build in Clover Basin or Somerset Meadows. Newer south-side subdivisions like Ute Creek, Fox Meadows, and Rider's Ridge have tight envelopes but expansive Front Range clay soil that cracks foundations and separates garage slabs, opening the pencil-width gaps mice use. Prospect New Town's alley-loaded garages and Mill Village's older detached garages are frequent first stops on an inspection. Irrigated lawns in Lake Park and Southmoor Park draw voles and pocket gophers, which is a different scope than a house treatment. Seasonally, Longmont mice start pushing indoors as canyon nights cool in September and October, boxelder bugs and cluster flies hit sunny south and west walls in the same window, and wasp calls peak July through early September along south-facing eaves. Colorado licenses commercial pesticide applicators through the Colorado Department of Agriculture; homeowners are entitled to ask for the applicator's license status and the product label for anything applied, and a straight answer should follow. Boulder County homes with vegetable beds, chickens, or dogs are common here, so product selection and re-entry intervals get discussed at the inspection rather than after the fact.
