Deluxe Aluminum Mouse Guard

We believe that this is the best entrance reducer and mouse guard on the US market! Made from sturdy aluminum, it should last forever. 

The mouse guard is reversible for feeding with a mason jar entrance feeder if desired. A fantastic feature! The feeder slot can also double as an additional entrance slot, for those times when you're building up a weaker colony and don't want a full entrance, but also need more opening than the 3 small holes.

This is the only entrance reducer you'll need all year long!
