Is anyone else having trouble with this? Every night the racoons graze my deck and backyard knock over trash cans even peer in my windows nothing seems to bother them or frighten them away someone had suggested amonnia soaked rags is a dish but that did not faze them in fact I was on my deck one evenng and this racoon just rambled across the deck like I wasn't even there.Any sugestions on how to keep them out of my property
