Mouse prevention

I'll share a memory from the good ol' days..
I would play hookie from school and hang out at a local auto repair shop. I still believe I learned more there than I did in school. Anyway, The 2 guys there would buy short cokes and pour salted peanuts in the bottle.One hand snack and no greasey /oily nuts. LOL This was a time when there was a 3 cent deposit on a soda bottle so when they first sent me on a snack run I asked should I grab a few of the many bottles laying around the perimitter of the shop to trade in. Their answer was no and I didn't request explanation.
Then the day came that one of those bottles began rolling around ( easily heard on a concrete floor ). AH HA ! the last swallow and a couple of peanuts was bait in a 3 cent mouse trap. The little fellow ould get his belly full then couldn't get out again. Into the dumpster it went.
