i'm thinking of gluing it to some plate, apply etch resist ink and then etch it in FeCl, just as normal diy pcb making, is it doable? |

Snails and slugs just can't stand copper and will not travel across it. Must be bare copper; no plastic film to protect the copper. |

There is also the hypothesis of them being "electrocuted" by copper, but I don't buy that. The chemical reaction seems more plausible. Kind regards, Samuel Lourenço |

That encourages them to go elsewhere. |

Apparently, copper sulfate also kills algae. Copper compounds are used in some pool/spa cleaners: http://lochlor.com.au/company-profile |
