Pest Control · Longmont, CO
Longmont sits where the plains meet the Front Range, and that mix shapes every pest call we run. Mountain snowpack delays seasonal pest activity into late spring, so ants and wasps often show up later here than people expect then arrive all at once.
Four distinct seasons bring changing pest pressures: cold winters push mice toward your furnace, summer hail and thunderstorms open roof and siding gaps, and hot sunny afternoons speed up insect cycles around yards near Sandstone Ranch or the old Longmont Sugar Mill grounds. We handle the full range for homes across 80501, 80503, and 80504 bed bug treatment after itchy overnight bites, termite inspection when mud tubes show up along a foundation, rodent control for scratching in the attic after dark, ant extermination for trails crossing the kitchen counter, and mosquito treatment around standing water. Older bungalows near downtown and newer builds in Lake Valley Estates need different plans, and we write both. Call (855) 681-0299 and we will schedule an inspection that fits your week.
Longmont grew out of the historic sugar-beet industry, and you can still see that story at the Longmont Museum and around the Longmont Sugar Mill site. That history matters for pest control: early twentieth-century bungalows and historic brick downtown buildings have settled foundations and older gaps, while chinook winds and sudden temperature swings along the Front Range push rodents indoors and shift when treatments should be timed.
We inspect first, explain what we find in plain language, and match the treatment to the property rodent exclusion for a Willis Heights ranch house, ant extermination for a bungalow near the brewery district, or wasp nest removal under roof eaves after summer storms. Expect scheduled follow-ups, clear prep instructions, and technicians who arrive when we say we will. Call (855) 681-0299 to book a visit.
Three calls dominate our Longmont schedule. First, mice and rats: freeze-thaw cycles open gaps around foundations, and hailstorms can damage siding and roof entry points on hail-prone roofs, giving rodents a way in.
We seal those openings and set tamper-resistant bait stations. Second, ants: summer heat accelerates insect activity, and heavy rain may displace ants and other soil pests right up against slab foundations ant extermination starts with tracing the trail to the colony, not just spraying the counter. Third, termites: termite inspection along crawl-space walls catches mud tubes early.
A quick self-check: run a hand along your foundation after a hard freeze and look for cracks wider than a pencil.

Yes water is the hidden driver of most Longmont pest problems. The semi-arid Front Range climate means almost every yard relies on irrigation, and irrigated landscaping can create localized moisture right where pests want it. Sprinkler zones near patios in Marnett or garden beds by the Longmont Museum keep soil damp, drawing ants, spiders, and mosquitoes to standing water in saucers and low spots.
Spring adds a second source: spring snowmelt can increase basement moisture, especially in older homes near downtown, and damp crawl spaces invite carpenter ants and spiders indoors. We follow EPA Integrated Pest Management principles fix the moisture, trim the harborage, treat only where thresholds are met instead of blanketing a yard with product. For a home backing to open space near Sandstone Ranch, that might mean mosquito treatment at a specific water source plus exclusion at the crawlspace door.
Check your own yard: look for sprinkler heads soaking the foundation line, and note where water pools two hours after a cycle. If you find both, we can help (855) 681-0299.
We route technicians across the whole city, and each area brings its own pattern. In Circle C Ranch, larger lots and irrigated lawns mean mosquito and ant work concentrates around patios and sprinkler lines.
Deer Run homes back to greenbelt space, so we focus on rodent exclusion at fence lines and deck voids. Lake Valley Estates sees newer construction where settling foundations open entry gaps within the first few winters.
Ken Dale and Marnett have mid-century homes with crawlspace vents and aging weatherstripping that mice exploit a mouse needs only a ¼-inch gap. Northwest Acres properties sit closer to open agricultural edges, where field rodents and displaced soil pests move inward after heavy rain.
One practical comparison: DIY store treatments rarely reach the colony or the entry point, which is why the same ants return each summer. Professional pest control ties inspection, exclusion, and monitoring together so the problem stops repeating. Call (855) 681-0299 and tell us your neighborhood we will bring the right plan.
Why us
Colorado Pest Pros treats Longmont homes and businesses with inspections and treatment plans built around Front Range conditions.
Dry spells, snowmelt, and sudden temperature swings change pest activity across the Front Range. We plan treatments around those patterns, so work matches what pests are actually doing near your property right now.
Every job starts with an inspection. Our technicians identify the target pest before selecting a treatment, then explain the findings so you know exactly what the plan covers and why.
We coordinate scheduling from Denver and route technicians across Colorado's regional markets, including Longmont. You get a straightforward appointment, a written record of products applied, and follow-up based on the treatment plan.
Our process
Here is how a typical service runs from your first call to the finished job.
You call or request service and tell us what you are seeing, where, and how long it has been going on. We schedule an inspection and set expectations for what the visit will cover.
A technician inspects the property, identifies the target pest, and locates entry points or harborage areas. You get a clear explanation of the findings before any treatment is selected.
We match the work to the pest and the site, whether that means bed bug treatment, wasp nest removal, or sealing out rodents. Products are applied at label rates with reentry directions explained.
We record products applied, treatment locations, and the service date, then keep children and pets safe until label instructions allow reentry. Follow-up is scheduled based on pest activity and the plan.
Through the year
Spring
Snowmelt and warming afternoons wake up ants, wasps, and overwintering insects around Longmont properties. Spring is a good time for an inspection that catches colonies before they move indoors or build nests under eaves.
Summer
Hot sunny days and thunderstorms push ants, wasps, and mosquitoes into peak activity. Hail-damaged screens and roof gaps give pests new ways in, so summer treatments focus on active nests and entry points.
Fall
Cooling nights send rodents and insects looking for winter shelter inside walls and attics. Fall service targets entry points and exterior zones before mice and spiders settle in for the cold months.
Winter
Snow and chinook winds drive rodents indoors while temperature swings move pests between wall voids and living spaces. Winter is a practical time to seal entry points and treat indoor activity with less exterior pressure.
Before you hire
Colorado pesticide applicator licensing and general liability insurance show the work follows state rules and that accidents on your property are covered.
A good provider identifies the target pest before selecting a treatment and follows label rates and sites, rather than spraying the same product everywhere.
Access to rooms, pets, and food surfaces matters. Ask about preparation steps, reentry times, and keeping children and pets away until the label allows.
Ask whether you are signing up for a single visit or an ongoing schedule, how follow-ups are priced, and how to cancel if the plan is not working.
