I live in a farming community. We are over-run with coyotes. A local trapper caught 100 coyotes on the 300 acres surrounding our farm in one season. It didn't make a dent. Coyotes hunt mostly at night. They love to den up under old buildings. They leave telltale signs in fence rows where they cross under. If you have a problem with coyotes, I would highly suggest that you consult a nuisance trapper for help, if you don't trap them yourself. I'd be happy to help you with information about trapping methods if these varmints are causing you problems.
