My nephew and I have recently discovered coyotes in the area. First week of gun seaon, he got one with his rifle. Since then we have been trying to trap them with no success. We boil the traps in walnut hulls, then dip them in parafin wax with a nail in between the jaws to cover everything, wearing rubber boots and gloves and we are having no luck. The traps are either being robbed or tripped and robbed. Any advice would be aprreciated.
