My business liability insurance does not cover my removals or anything to do with beekeeping, I have a standard "waiver of liability" form, they don't sign I don't remove bees. I've left some too. In a tree, with the owner right next to it.
My homeowners insurance is Allstate, hives were not an issue. Standard homeowners liability is like 100,000, I have big dogs so I carry $300,000. Used to have a big dog that treed teenagers and did bite now and then, got the coverage for him and my ponds. Have never had a claim.
I manage my hives so they don't get too hot, and am well fenced and do not advertise that I have bees.
