re: Three copperheads already??
They were babies. Got two with the weed eater. I didn't see them until after I got them. The third was up by the door. The cat has also killed a couple.
We don't have rocks around here, but a lot of pine needles and underbrush. Lots of woods around here.
The kids are afraid of snakes. I keep their play areas clean. The cats also help.
