On debs recommendation, I just left mine. They just dry out. I can rattle one but they just dry out. I love mine.
Or you can just shoot them yourself.
Wow, that's a LOT of work! Have-A-Heart traps them easily and you don't have to wait around.....knowing me I'd slip while I was turning the darn thing over on them and the skunk would spray me and wattle off! We (and when I say we, I mean my husband
) trap them overnight. Shoot them in the morning and dispose of them when he gets home at night. He doesn't cover the trap. Just walks over and shoots them. He's tried to shoot them in a way they don't release their spray but when they relax it's released. But they don't spray at him. It's like they're in shock after being in the trap.
I hate when we catch skunk!
