As best I can tell, raccoons don’t like crystallized coyote weewee any more than tiggers like haycorns. I haven’t seen any repeat visits from the little attractive nuisances.
It looks like they may have overwintered in a disused playhouse on my neighbor’s property, but overhanging mine: it’s a two-story structure and the upper floor is carpeted with raccoon deposits. Yuck.
It doesn’t seem terribly effective on squirrels but they weren’t my primary target. I can now turn my attention to them and see if I can find something that will work on them.
