I too have a 16 foot high arena. You can buy rifle shells for .22 rifles that are loaded with shot rather than a single projectile. This shot will not penetrate the building or even the insulation. What I have is Winchester NO. 12 shot. It is made for this and similar purposes. We ended up shooting a bunch of them and then the rest just left and none ever came back. I don't like doing it but it was the only way we could find to rid ourselves of them . They will reproduce worse than rabbits if you don't get rid of them.
I read your next e-mail about steel spikes to put on cross beams and that would certainly be a preferable method if it works. Good luck, please let us know how you handle the problem.
