I have a bumble bee nest located in the front of my lawn. I want to protect the nest, but also don't want our landscapers to get stung when they mow. I am thinking of putting a small fence around it and not mowing within the fence. My question is, how deep is the nest? If I stick the prongs of the fence in the ground and possibly hit the nest, this could possibly make a queen mad and I would get stung. Putting it up at night seems to be my thought, hoping they would be asleep. Any advice is appreciated.
