Bald face wasp? #894588

I think I have a bald face wasp nest in my pine tree. What can I do to remove it?

Montgomery County Maryland

Expert Response

Nothing needs to be done, because social wasps (including hornets) in our region do not re-use old nests; a single female (queen) starts a new nest from scratch every year, and usually in a different location. No workers from an old nest survive the winter, and old nests will fall apart on their own and don't need to be removed.
