Wasps come in many different types – nesting in attics, under eaves, in retaining walls, or in the ground. Like bees, wasp colonies can become large and pose a threat to your property. If wasps invade your attic, they may penetrate your drywall and eventually swarm your home. Prompt treatment of wasps will protect both you and your property.

Yellow Jackets have very distinct abdominal color markings of yellow and black or white and black. Yellow jackets are responsible for most stinging related incidents in Colorado. Yellow jackets typically build nest underground in abandon rodent burrows or spaces between rock landscaping. In early spring, a queen will begin building the nest and nurturing offspring. The “workers” will begin foraging for food in early summer and are know to scavenge trash and other human food sources. During late summer, males emerge from the colony to mate with fertile females. Fertilized females will seek hibernation for the winter and start new colonies the following season. The old queen and the workers will abandon the old colony at the end of summer and will not survive the winter.
NOTE: Aerial Yellow Jackets can build large paper nests under eves and in attic spaces.
Bald-faced Hornets are actually related to yellow jackets. They are given the name hornet due to their size and nesting habits. Bald-faced Hornets typically have black and white markings and build their nests in trees or scrubs. The nests are typically oval or tear-drop shaped and consist of a papery material. Much like yellow jackets, Bald-faced Hornet’s nest are built each season by an overwintered queen. Old nests are typically abandoned by late fall and will not be used in subsequent seasons.
Paper Wasps are typically black in color with yellow markings. They build open-faced nests with hexagonal cells along soffit areas, playground equipment, and other small cavities. Paper Wasps are not aggressive, but are able to sting. They feed mainly on live insects and insect larvae. Like other wasps species, only the fertilized females survive the winter. Old nests are abandoned late fall and other members of the colony do not survive the winter. New queens will build new nest the following season, but may build in the same location.
MUD DAUBER WASPS
Mud Dauber Wasps are typically black with yellow bands across the body and legs. They have very thin bodies with an elongated division between the thorax and abdomen. Unlike the wasps above, Mud Dauber Wasps are solitary and typically pray on spiders. They are not aggressive, but will sting if they come in contact with a body. The female Mud Dauber Wasps build cells of mud in protected areas under eves or in cracks and corners of buildings. Each cell contains a paralyzed spider for the larva to feed on once hatched and multiple generations can emerge each year. Any larvae in the nests will go dormant after August and will emerge the following season.
