I am having a terrible time with some kind of critter coming into my yard at night and digging up my turf. My yard is surrounded by 6' high vinyl fence and I have plugged all the holes dug under the fence, so critter must be climbing neighbors' trees and coming across the top of the fence. I am very respectful of the birds and pollinators that feed in my yard and do have a cat that goes outside for a couple hours each day, so I am careful about toxic substances. I have seen scat that is ambiguous--a lot looks like skunk scat but some also looks like raccoon. Critter is really getting aggressive--pulled down a birdfeeder--and my yard is a mess. I hate to remove all my bird feeders that may be attracting mammals. Earlier in the summer we had a groundhog that was trapped and relocated, but would like to avoid traps now if possible. I am desperate for any advice you can give me. Thanks so much!
