How do you keep birds out of your barn? But, without a barn cat? I've heard some people use nerf guns or something like that, which, if you shoot them at the birds enough, they stay out for good.
I'm having a barn built which is why I ask. Is there something in barn design that helps keep them out? I'm going to have exposed ceiling beams and structure, which I'm aware is a perfect bird perch.
It's hard because you want good ventilation obviously, but that also invites other animals to come in.
