Yes! I did a comparison a few years ago and put copper tape around one pot of annuals and no tape around the other. The petunias in the pot with the copper tape did not show any slug damage while the other pot had petunias nibbled on all summer. I hope you have the same results. Write back and let us know. I have seen some garden centers and home improvement stores sell the copper tape with one side sticky made to use around pots. Mine lasted for many years. Keep growing, Marianne Binetti
