Behavior

These social wasps build large, football-shaped aerial paper carton nests, which hang in trees or shrubs, or under eaves. They can be extremely aggressive when their nests are disturbed, and will attack repeatedly. Bald-faced hornets are more commonly found in wooded foothill and mountain areas, and are most active in the summer and early fall.

Treatment

Aside from their aggressively defensive nature, these insects are largely beneficial, so if you can live with their presence, the bald-faced hornet will help control other insect pests, killing them to feed the larvae in its nest. If you decide you can’t live with an active nest nearby, call a licensed pest professional; it’s a risky proposition to try to dispose of it yourself. Your well-trained Clark Pest Control technician will know how to remove a hornet nest.
