There are also 'Other' insects that produce a sweet byproduct that bees will collect & they are lumped into 'Honeydew' out here. This is a bug in the bark of a white oak that produces a foam & clear sweet sap like secretion, in large amounts.
The tree is by & over a wood deck with a 'Kiddy Pool' and has about three hundred honeybees working it! The infestation only goes up the trunks (three trunks) about twenty five feet. Five or six other trees have no signs of secretion, only the pool tree.
Other then cutting it down or spraying it with dormant spray this fall I'm stumped.
