So I had a rodent problem when I bought an older house recently. I had a bunch of remodeling done and after quite a few months of vacancy the house became home to Raccoon, Opossum, And who knows what else. I have since sealed any access to the house and currently have no more uninvited guests around. I asked for advice here and someone told me to get a motion detector sprinkler. I did and I put one out front and 2 in back. They work pretty well....Blue Jays get angry but they seem to come back for more water fun! I have forgotten many times to turn it off and soaked myself walking through the yard....I rarely forget now. I was just watching a couple 18-20 year old kids driving a mini bike up and down my road. It broke down in front of my house and watching them try to fix it was hilarious. So they decided to get shade and move to under my apple tree.....I did not like them in my lawn. I was standing up to go holler at them when WHOOSH one got sprayed in the back as he sat down on my lawn.....He looked so scared....It was awesome. Then they looked confused and the other went to wheel away the bike he leaned on my tree and again WHOOSH right in the privates.....again completely confusion like watching monkeys out there. The other one decided to "inspect" what was happening. Kid started crawling toward the sprinkler...WHOOSH in the face and they got the hell of my lawn! I now owe much thanks to the advice on here. Getting those DID help with rodents but 5 min ago it gave me more joy than can be described.
