Q: I have these insects at my home. I see individuals going behind my house’s fascia. Do I have a huge problem?
A: You have European hornets. These large stinging insects typically build a nest in empty hidden spots, like a hollow tree or a house wall. In contrast, the common bald-faced hornet builds a gray, football-shaped nest in trees and under eaves.
European hornets can be aggressive if disturbed. In the interest of safety, you should call a pest control company to send someone to kill the hornets.
