They have been observed consuming meat, spiders, fruit and insects. Adults will also drink flower nectar which they feed to their larvae.

The wood fiber mixes with their saliva to become a pulpy substance that they can then form into place. The bald-faced hornet lives in North America, including Canada, the Rocky Mountains, the western coast of the United States, and most of the eastern
