At some point in the fall the field mice start looking for a place to winter over. Just when should a bee keeper place mouse guards over the entrance?
What do people use and how do they fasten it in place?
Last year I used a small (1inch opening) entrance reducer I made my self with 1/4 inch hard ware caolth stapled with an arrow stapler over that entrance. I put in place about mid Oct.
But this year I am using screen bottom boards rather than the old style and the entrance is bigger with out a entrance reducer although I could faction a smaller entrance I guess.
