What lures do you find best at enticing a digging response from coyotes?
A snare! Many time I get a habitual digger, if I snare a female, that's usually the end of the digging.
Or just use the coyotes urine to make a post set up wind nearby, or flat set, no lures just gland lure or urine, sometimes I use wet dirt, Yellow snow, or bladder urine from one or two to make a set to get uncooperative ones
