Bald-faced hornets in Montclair's big trees
Montclair is known for its large, old trees β oaks, maples and tall evergreens over yards, driveways and sidewalks. They're also where bald-faced hornets like to build. A bald-faced hornet is black with white markings on the face and the end of the body, a little bigger than a yellow jacket. The nest is a gray, layered paper ball with one opening near the bottom, and by late summer it can be as big as a basketball.
What makes these nests a problem:
- They're defensive. Hornets guard the nest and will come out in numbers if a branch is shaken, a mower runs underneath or a ladder touches the tree.
- They're often high. Many nests sit 15 to 30 feet up, or deep inside a hedge where you don't see them until you're trimming it.
- They're hidden by leaves. A lot of people first spot the nest in the fall, after the leaves drop.
If you find one, keep everyone out from under the tree, hold off on mowing or pruning nearby, and send us a photo. Don't throw things at it or spray it from the ground β that's how people get chased.
