Please remove the nest in the early morning hours when they are sleeping so you don't get stung. Best do so when it's also colder and they are less active.
We have hornets that go into the ground and nest, those you have to be careful not
to step in!! I did so some years back and it' wasn't a pretty picture! I am on the second year of venon therapy for hornet stings. According to the information there are 3 types of venon therapy bees, black hornets and yellow ones. Just be careful!!
JT used to have hornet information on his website.
