Yea - I usually hav bank behind r peace of wood r grass
The trap against the high bank - I think the animal just hit it from the side - I put hole deeper to make it work more
The other trap had more backing before I caught 2 coyote off it in 2 days - they wore some of backing down - I put a few dirt clods around that one this evening to semi direct dog but it is not obvious and I put small clump grass behind the worn down hump- I put hole at angle always and I made that hole deeper today
Good news is you are getting interest in the hole, so hopefully more coyotes will go down soon.
