Redneck mouse trap. This is the best mousetrap ever... Use a 5 gal. bucket with a gal. of RV antifreeze dumped in the bottom, a plastic pop bottle with a welding rod thru it and some peanut butter on the middle of the bottle. Lean a board (2x4) up against the side and it works all year without checking it and no smell. I love rednecks, as they are the most ingenious group of people I have ever seen. Redneck Mouse Trap No Smell! Easy clean up with a set of BBQ grill thongs and a Walmart plastic bag to hold the dead carcasses. Mark the level with a black Sharpie and fill as needed over time from evaporation.
