No, they're not...release corpse, re-bait, and re-set...wash hands thoroughly. But.... Oh, yeah, they won't get multiples like a bucket will. I didn't care for emptying the buckets, and the size of them, eventually they stopped working anyway. I just have multiple snap traps set in several places(garage, sheds, kitchen). Am able to keep them under control by constant traps set. Fall needs more attention as the weather cools.Besides, snap traps are one and done.
Yes, have nipped fingers many times or just scared myself if one goes off and jumps out of my hand......but after the first 5 years of my 20 years stint here, I have gotten pretty darn good at setting them without mishap. Now, rat traps are another story.I usually get snapped by the trap when I try to use those.
