I have a lady with a Catalpa tree where bees have moved in. The opening is about 4-1/2 feet off the ground and is a long oval, like the tree split. It faces the sidewalk. She wants me to remove the bees and of course the only way to do this is via a trap out. She does not want them killed, just relocated. The bees have only been in the tree a week or two. I am somewhat concerned about the liability since it is near the sidewalk, about 4 feet away. She put a sawhorse out with a sign that states there are bees in the trees. People could of course cross the street. This is a small town and it is not like there are a lot of people walking around. Anyone had any experience with liability issues? I was thinking of erecting a tarp between the tree and the sidewalk to act as a barrier. Thanks for any help on this issue.
