Having been reminded that coffee grounds are a folk remedy for deterring

Apparently it is illegal to use any untested product as a chemical
deterrent.

Mulching to add organic content is fine, though.......

Ignoring the above for the moment, has anyone tried this and does it work?


I throw our coffee grounds onto our front garden which has always
has a large snail population despite my best efforts. Does not seem to
make much difference, they are still there in numbers. I understand
some research has been done on caffeine which has proved to be a slug
and snail deterrent, not much caffeine in grounds.


I was told a long time ago that there are certain plants that slugs
don't like to eat.
if these could be identified then perhaps they have a chemical in them
that might make an effective deterrent?
