How to identify bald-faced hornets
Large (3/4 inch), black with ivory-white face markings and white pattern on abdomen tip. Aerial gray paper nests, football to basketball sized, with single entrance hole at bottom.

Yellow jackets (smaller, yellow markings), European hornets (brown), paper wasps (smaller nests)
Why bald-faced hornets are a problem in Massachusetts
NH forests and landscaped areas provide nesting sites. Outdoor recreation puts people in contact with nests. Nests often develop unnoticed until late summer.
Where they are commonly found
In trees and shrubs, 3-60 feet up. Under eaves and overhangs. On building sides. In attic spaces with exterior access.
Signs of bald-faced hornets
Large gray paper nest visible. Significant hornet traffic. Increased hornet presence. Aggressive behavior near nest area.
Damage & health risks
Damage caused
No structural damage. Danger is entirely from aggressive stinging behavior near nests.
Health risks
Can sting repeatedly and pursue threats. Mass attacks can result in multiple stings—dangerous or fatal even for non-allergic. Anaphylaxis risk for allergic individuals.

Bald-faced Hornets questions from Massachusetts residents
Very dangerous. They're extremely aggressive, posting guards that attack anyone within 10-15 feet. Each can sting multiple times. Mass attacks can be life-threatening.
No. Colonies die with frost, only new queens survive elsewhere. Nests are never reused.
You can leave the nest until after hard frost. But until temperatures stay below freezing, active hornets may remain. Nests near activity areas shouldn't wait.
