My grandfather would pee in an old coke bottle then go out and spread it along the fence to keep the coyotes out. Never once saw a coyote in the yard though we would see them sometimes peeing on the fence.

Side note:
Where I work is a 400 acre campus in the middle of the St. Louis suburbs. The area is considered a nature preserve. We have deer, turkeys, owls, redtail hawks, and coyotes.

The coyotes would sometimes go after family pets when the rabbit population went down.

The coyotes normally are very shy and we only see them from dusk to dawn. There was a particular one that was kicked out of the family group and spent days being un-coyote before he disappeared. During they day he'd lay down in the middle of the parking lots, or along the side walk. We'd have to have coyote watches set up. People started to try and feed it.

It was a bit strange watching an animal behave so out of character we considered having someone come in and put it down.
