You did what was necessary for sanitary health and protecting you and your family. It's unfortunate, but the rat had to go one way or the other.I finally got it. It was a big one. The snap trap was definitely not as instantaneous as they claimed in the ad. I wish I could've caught it alive. But you all are right. It would be wrong to release one for the next person to deal with.
I tried many foods for bait. Ultimately, it was a peanut in it's shell which proved irresistible. I'm just glad I didn't have to resort to a glue trap. Still I feel bad for little Emile.
I don't think there are more. But I'll keep traps out and try some more bait deposits around traps. To see if anything gets eaten for the next week. If nothing disappears. I'll assume that was the only one.
Hopefully there aren't any more than the one.
