Re: Kids shooting at my hives with a pellet gun?
Annoying, but little you can do, and a sign will not deter this activity.
Had the odd (real) bullet hole in my hives, always been a one off and not recurred, and never done serious harm.
But if you are serious and caught them with a game camera, a word with the parents may work.
About signs. In my view a unfriendly No Trespassing type sign only antagonises certain personality types. A friendly sigh such as Take Care, Bees Working Hard is non threatening and may provoke empathy rather than aggression.
