Poison in a residential area wouldn't be a good idea. I hate cats but some kids cat will eat the same thing a coyote will. Your best bet would be a pellet gun. You can get a very powerful one that will shoot at least 1000 feet per second. If you hit a coyote in the rib cage with that it will not kill it right away but it will in a matter of minutes. You must hit it right behind the shoulder when it's standing broadside to penetrate the heart/lungs. A pellet gun will be quiet enough where it shouldn't wake the neighbors. For $370 you could get this gun which will definately dispatch a coyote: http://cobraairguns.stores.yahoo.net/rws-2166150.html
