Wasp and Hornet Removal in Longmont, CO

Understanding Wasp & Hornet Problems in Longmont, CO

Wasps and hornets are a reliable seasonal concern for Longmont property owners, and the city's geography gives them plenty of nesting territory right alongside residential neighborhoods. The open space near McIntosh Lake, the St. Vrain Creek Greenway, Roosevelt Park, and the agricultural land bordering the city's eastern edge all support large wasp and hornet populations that forage into adjacent yards and structures throughout the active season. Yellow jackets are the species responsible for most stinging incidents in Longmont, building colonies underground in lawn areas and open ground as well as in wall voids, attic spaces, and behind siding in older homes with gaps in soffits and fascia. Bald-faced Hornets build the large football-shaped gray paper nests commonly seen in trees, under eaves, and on utility structures, and Western Paper Wasps build smaller open-celled nests on porch ceilings, window frames, and sheltered surfaces throughout the city.

At Longmont Pest Control Experts, we handle every wasp and hornet situation starting with an inspection that identifies the species, locates the nest or nests, assesses the colony size, and determines whether the infestation is in an exterior location or inside the structure itself. In-structure yellow jacket nests in wall voids require a very different treatment approach than a visible Paper Wasp nest under an eave, and treating the wrong way — or sealing an entry point before the colony is eliminated — drives wasps deeper into the structure where they can chew through drywall into living spaces. Every treatment we provide is built around what the inspection confirms, with the protective equipment, product selection, and timing that the specific nest type and location requires.

How to Reduce Wasp and Hornet Activity Around Your Longmont Property

A few preventive steps taken early in the season can significantly reduce the likelihood of wasps establishing nests on or near your property. Here are our recommendations:

• Inspect soffits, fascia boards, siding gaps, and vent openings in early spring and seal any openings before queens begin nesting
• Remove old nest structures from eaves and sheltered surfaces in late fall or early spring to avoid attracting new colonies to the same site
• Keep outdoor garbage bins sealed and rinse sweet beverage containers before disposal to reduce the food attractants that draw foraging yellow jackets
• Remove fallen fruit from yard trees promptly as fermenting fruit is one of the strongest late-season attractants for yellow jackets
• Cover outdoor food and beverages during meals and gatherings, particularly in late summer when yellow jacket colonies are at their largest and most aggressive
• Do not disturb a nest you have discovered — keep people and pets away from the area and contact a professional for assessment
• Schedule an early-season perimeter inspection before peak nesting activity begins if your property has had recurring wasp problems in previous years
• Cap chimneys and repair damaged screens on attic vents to prevent yellow jackets from accessing interior structural spaces
