I suggest a Walther pellet handgun without blowback (or get it in rifle form). I got one to take out squirrels and birds if I had to do that to keep my growing food. Unless it a SHTF type of thing, I'll use netting and row cover instead of killing them. But if it is them or me and I need that food, they are going to die.
At my house it goes like this.
Either there’s peppers in the skillet, or the critter that ATE the peppers in the skillet.
One way or another...
