I had a mouse problem in my garage. Baited four new wooden Victor mouse traps and came up empty several days in a row. First the cheese was nibbled off, then the peanut butter licked off.

Looked on the website for victor and found out mice love chocolate. My daughter offered to melt some chocolate chips and load the traps. After the chocolate cooled on the trigger, it wouldn't come off. Microwave the chips just long enough that they just melt. Apply to trigger.

Caught 4 mice in and hour and the other 4 by morning. Every trap had a mouse. The chocolate had light teeth marks, but was largely still there. Too hard for the mice to get a good bite. Best part is the chocolate is still working a year later. I catch a mouse every now and then and reset the trap.
