I would use something wider than copper wire...tubing or wide strips would be best...

They would need to come in direct contact with it...so keep it a little above the mulch line. Also, it works best if clean, so as it tarnishes, you might want to take a bit of sandpaper to it every now and then...

Thanks, Webkat. How wide should the strip be? What should I ask for at a hardware store? I've seen it in garden centers but not paid any attention. Seems I should be able to find something in a hardware store.

Just tell them what you want to use it for and they should be able to direct you to something that will work...

I would say an inch across should be just fine.

I saw some copper tape for slug and snail control at the nursery I went to Sunday. It was an inch wide.

interesting. why dont the slugs like copper?
