Squarls make good target practice. I have a large garden in the back that the y dig up to bury nuts in. Drove me NUTS!!! Got a good pellet rifle and taken to squarl huntin'. I believe they got the hint because they are still in my neighbors yard but rarely in mine. I don't use a .22lr or the like because I live within city limits. If I lived out of town a bit I would definitely have a varmint gun sitting by the back door ready to go.
Hope this helps
