I have a louvered vent window close to the ground in one wall of my small greenhouse. It's become an entrance point for mice and shrews during the winter and for chipmunks once the weather turns warmer. I can set traps for the mice and shrews but the chipmunks - not so much. I had to remove plants under lights on a lower shelf because the chipmunks were coming in to sample the "salad buffet". Any ideas/plans for constructing a screen to place on the outside of the GH wall?
