Go to My BYC Page under my tag on the left - you can see pics of hardware cloth - it's the most durable cloth you can use - stock panels probably last longer, but the holes are too big with all the critters I have roaming around this area. Do not use chicken wire (larger traditional looking) as it will rot faster and raccoons can reach through it. I'm not sure how long it will last, but I know it will last longer than chicken wire (aka poultry netting).
