The bald-faced hornet gets its name from its strikingly white face and black and white body, technically is actually a yellow jacket. The coloured patterns and markings on the abdomen identify the role each hornet has in the colony. The bald face workers are relatively small in size compared to the queens which are the largest members of bald-faced hornet colonies. Adult bald faced hornets feed on nectar, pollen, meat, caterpillars, aphids, and their competitors – yellow jackets and wasps. Because of the way they so aggressively protect their nests, these stinging creatures are rather dangerous. In the world of most painful insect sting, the bald faced is right behind bullhorn ants and fire ants. I am often asked how I can prevent these hornets from building a nest in my yard. The answer is always the same – you can’t. Short of removing all foliage from the yard, prevention of bald-faced hornets is impossible to achieve. But, reducing access to overwintering sites indoors can be done by finding and sealing all cracks in the foundation of your home. And finally, tightly seal all garbage containers and trim shrubbery and trees to reduce the number of potential nesting sites.
