in PA, a yelping/barking combination for about 15-25 mins. will work well. but, you have to have a rabbit distress call also. try going where you know there is a coyote, go on his/her land, yelp and bark about 5 min. they won't care much if you're on their land. but then, do a rabbit distress and they will really get mad and usually come in that way. make the rabbit distress callreally exagerated. wait for however long and maybe just bark just a little every now and then after about an hour. or you can just walk around and wait an hour, then bark/yelp again. oh, i'm down here in PA with my one friend and we both don't know if you can hunt coyotes at night. if so, are there any times you can't shoot coyotes during the night.
