My wife spotted a Bald Faced Hornet nest about 35' up in one of our Pine trees. It is about 90 yards from the Apiary (3 hives). We have not seen any of the Hornets at the hives yet. The Hornet nest looks like it's still under construction, only 7 or 8" in diameter. Very active though.
Is this something to be concerned about? I've read differing accounts in other posts regarding Hornet marauding of hives, and weakening hives to the point that other pests can do more damage.
