No, the 1/4x1/4 square mesh stuff. Trying to find a way to seal up the new storage shed from mice before I put the sheet metal sides on. I've got the rat strips and J channel stuff but last shed, that didn't keep the mice out. the local exterminator recommended I use 1/4 x 1/x4 square steel mesh aka hardware cloth. I need a 120 feet of it and its about 1.50 per ft
