I use copper tape. I have 20 or more hostas without slug damage. It is not a total protection ...slugs or snails in the compost would be unaffected.....but it certainly is not a myth. A friend of mine has a treasured old violet that struggled to survive slug attacks. I bent a copper pipe around it 2 years ago and it is very effective. Copper tape is cheap. If it works for you then great. If not what have you lost! grit, sand, egg shells and similar do not generally work....beer traps have some element of control but who wants drowning slugs on display?
However, thanks for the info, the helpful herpetologist, re the bufo bufo. learned something
