Non-Chemical Deterrents to Repel Slugs - HereOnThePrimalEdge - 06-19-2019
Slug barriers, including copper wires and mesh, aluminum flashing, and hydrophobic paints, were tested last year at the Waimanalo Research Station for their effectiveness against slugs. If you grow vegetables, their findings will help you minimize the risk of rat lungworm vectors in your garden or greenhouse.

FWIW, everything you listed is a chemical!
Language matters.

I bet a smaller slug can cross the gap between the electrically charged wires without touching both at the same time and can proceed without getting a shock.

Ozone (esp if solar PV generated) irrigation of fields has been used as a very effective oxidizing molluscicide....
& Java junkies may wanna try caffeine...
We had used copper barriers, but found that after a time, the barriers are not as effective.. One problem with deterrents, they do nothing to reduce the mollusk population.... just keep them, somewhat, at bay...
We have switched over to propane flame weeding for our large scale weeding & have noticed a huge reduction in slugs/snails...& it has been drier in the last couple of ears... so there is that...
Caffiene as a deterrent:
