If every time you see a coyote, you shoot it dead, the other coyotes in the area WILL learn not to enter your "zone". That is what kept them away from us in the past, and works everywhere it is tried.
Stay away or die. Simple, yet quite effective.
I agree and disagree. Coyotes are very smart. They learn quickly that humans can kill them at a distance, and become very sneaky and clever about raiding or crossing a particular piece of property when the humans aren't around. But if it's clear that no humans are around, they'll still venture onto your land. Believe me, we shot lots of coyotes when I was a young girl and they simply became more careful and devious, coming onto the property to raid only after twilight.
In the West humans learn that one way around this is to kill the coyotes and nail the corpses to fence posts at regular intervals, as a reminder to the brethren of the dead coyotes. This is probably not a solution that would be met with enthusiasm in most suburbs, unfortunately.
