Wasps are one of the most common, and most feared pests in Colorado. Unlike bees, which are typically focused on pollination, wasps are more aggressive and territorial. They can sting multiple times, making them a serious concern for homeowners, business owners, and property managers.
In Colorado, wasps become especially active in the warmer months. You’ll often see them hovering near patios, trash cans, decks, and entryways. While they do play a role in controlling other insects, their presence around people can quickly become dangerous, especially for those with allergies.
Seeing wasps near your roofline or eaves? That likely means a nest is already established. Wasp colonies grow rapidly through summer. Early removal is safer and easier than waiting.
Types of Wasps Found in Colorado
Most Recognizable
Paper Wasps
Build umbrella-shaped nests that hang from eaves, decks, and railings. While not as aggressive as yellowjackets, they will sting if their nest is disturbed.
Most Aggressive
Yellow Jackets
The most aggressive wasps in Colorado. Often mistaken for bees but more slender and highly territorial. Frequently nest underground or inside wall voids. Responsible for the majority of wasp stings in the state.
Highly Defensive
Bald-Faced Hornets
Technically a type of yellow jacket. Build large, enclosed nests in trees and shrubs. Highly defensive and will aggressively protect their nests if disturbed.
Generally Beneficial
Mud Daubers
Less aggressive and rarely sting. Build small, tube-like nests out of mud on walls, garages, and sheds. Generally considered beneficial because they prey on spiders, though their nests can be unsightly.
Seasonal note! Wasp aggression peaks in late summer and early fall as food sources decline and colonies reach their largest size. Spring and early summer, when nests are small, is the safest and easiest time to address a wasp problem. Most wasps die off in winter, but fertilized queens survive to start new colonies in spring.
FAQ: Wasp Questions

Why Do I Have Wasps?
Wasps are attracted to environments that provide food, water, and shelter. Common attractants include:
🗑️ Open trash cans or dumpsters
🥤 Outdoor food and sugary drinks
🐾 Pet food left outside
💧 Standing water sources
Late in the season, wasps become more aggressive because their natural food sources decline, causing them to seek out human food more frequently.
Where Are Wasps Found?
Wasps can nest in a variety of locations around homes and businesses. Many nests are hidden, especially underground or inside walls, and can grow quickly before being noticed.
