We too had multiple critters eating things in our yard in Ohio. The main problem was Canada Geese. I just wanted to keep them out of our yard. because they poop so much. We tried fireworks, laser light at night, spraying the eggs with Pam, chasing them, many other exhausting things. So we move to The Villages and I carry my motion detector sprinkler with me. I had to use it the first summer to scare the rabbits. And scare it did. It is a sprinkler that can be set to set off a 3 second burst of water when anything crosses the path of the beam of the motion detector. It got the rabbits, the yard man, the neighbor, me, the meter reader, everything that moved through the beam. There is a video on youtube:

They are much cheaper than they were when I bought mine in about 2004. I paid $79.99. I think they run between $39.95 to $59.95 now. Walmart has them that can be ordered.
