We have a problem with foxes but luckily they only seem to come around late nights early mornings so we wait till sun is up to let them out and they always put themselves to bed before it gets dark it's gonna sound funny but my husband marks around that part of my yard with his urine I thought he was nuts but for past 4 months it's been working even the deer are staying awaydarn. if only i would've known of that. sadly we have(had?) coyotes and i don't think that would stop them
