My neighbours have a problem with a pair of coyotes frequently coming v

Was wondering if anyone could suggest some aversion therapy (other than
bullets or poison) to help deal with the problem.

We had this issue come up in our neighborhood recently. We're in a
suburban community which happens to not be in city limits (thank God).
Coyotes have been coming into backyards and making a racket, probably
thinning the cat population.
At a neighborhood association meeting we asked the sheriff's deputy
attending, for advice. "Shoot 'em. They aren't protected, they will eat
your pets and they can threaten humans".
