Pest Guide: What to Know About Bald-Faced Hornets

Identifying Bald-Faced Hornets: Common Features

Bald-faced hornets are social wasps known for their unique black-and-white markings and basketball-sized paper nests. These swirling gray nests are typically found on outdoor structures, but the hornets can move indoors if given the opportunity. Males can be aggressive and are ready to sting anything they consider a threat, while females are more docile. Males and females range from 5/8 to ¾ of an inch long, with queens larger than most others in the hive.

Two things in particular draw bald-faced hornets to a property: wood and water. Queens find places to hide in the winter until the spring when they emerge to rebuild their hives. They find wood, such as from old tree stumps or wooden parts of your home like soffits or furniture, and begin consuming it. They use cellulose from the wood to make paper, which they use to construct their hives.


Common Questions About Bald-Faced Hornets

Bald-faced hornets are as dangerous insects, especially to small children or animals. Suppose someone disturbs their hive. Up to 400 hornets may attack, many ready to sting multiple times. While a single sting isn’t likely to cause significant harm, a hive attack could.

Bald-faced hornets can be dangerous to take on by yourself. In addition to facing attack, even if you manage to destroy a nest, the queen could escape and rebuild elsewhere. That makes it essential to have any hives you identify removed professionally.

You can prevent bald-faced hornets from moving into your property by clearing rock piles or brush that could provide a winter habitat for hornet queens. Covering outdoor wooden furniture, replacing it with plastic or treated wood, and removing old stumps and wooden fences can also deprive black-faced wasps of their construction materials.

Tips for Preventing Bald-Faced Hornets

  • Keep your trash cans tightly closed.
  • Avoid leaving food or drinks out in the open.
  • Seal any cracks or crevices in your home's exterior.
  • Have your property inspected regularly by a pest control professional to identify any potential nesting sites and remove them before they become a problem.
