If I couldn't kill it with a hoe, I'd go ahead and shoot it. Buy some 22 caliber Calibri bullets. They contain no powder and are quiet. I would bet they have a very limited range and have not known of one ricicheting.
I knocked a squirrel out of a tree at 85 ft. using the calibri. Lucky shot? Yep. However, the bullet did its job. They are so quiet that I'm using them on squirrels in my back yard in the city. They have chewed 2 holes in the side of my house. Even with a limited power bullet, I'd follow all of the normal safety rules.
