Mother Nature has a way of revealing many of her secrets when the ground is bare and leaves have fallen from the trees.
Irvington reader, J.O., “I recently discovered a bee hive in the maple tree. Do the bees return to the hive and hibernate for the winter?”
Most likely, the nest belongs to bald-faced hornets (Dolichovespula maculata), a North American native insect that actually is in the wasp family, related to yellow jackets.
A bald-faced hornet’s nest can be as long as 3 feet with a roundish appearance. The entry and exit hole is toward the bottom of the nest, but usually off to one side. A nest may hold several hundred residents, which live in the familiar caste system of social wasps and bees: queens, workers, drones, new queens.
These black and white hornets are quick defenders of their nest and can get quite aggressive if disturbed, stinging repeatedly.
When the temperature reaches freezing, bald-faced hornets die. Recently fertilized queens hibernate under ground and do not return to last year’s nests.
“Bald-faced hornets do not return to the same nest; each spring female hornets that have survived the winter will find a new location and begin anew,” said Jerry Zimmerman, an experienced beekeeper and physics professor at the University of Indianapolis. “After the first hard freeze it should be safe to cut down the nest.”
If you can’t reach the nest, it will deteriorate naturally.
