Bald-faced hornets are large black-and-white wasps that build big gray paper nests in trees, shrubs, and on eaves. Highly defensive of the nest, they are a common late-summer stinging hazard on Whidbey and Fidalgo properties.
How to identify bald-faced hornets
About 3/4 inch, black with an ivory-white face and markings — larger than most local wasps. Their football-shaped gray nest can reach the size of a basketball by late summer.
Behavior & season on Whidbey & Fidalgo
A single queen starts the nest in spring; the colony grows through summer and is largest and most aggressive in August and September. They defend the nest vigorously and can sting repeatedly.
Why bald-faced hornets are a problem
They deliver painful stings and will attack in numbers if the nest is disturbed, a serious concern for anyone allergic. Nests near doors, decks, and play areas are especially hazardous.
Signs of bald-faced hornets activity
- A large gray, papery, football-shaped nest
- Black-and-white wasps patrolling near the nest
- Aerial nests in trees, shrubs, or under eaves
- Peak activity in late summer

Frequently asked questions
Should I remove a bald-faced hornet nest myself?
No. They defend aggressively and sting repeatedly. Professional removal is far safer, especially for anyone with an allergy.
Why is the nest suddenly huge?
Colonies build all summer and peak in August–September, which is when nests become most visible and most defensive.
