The majority of copper stripping sold in garden
shops for this purpose is not wide enough to create an effective
barrier,
which would need to be six inches wide, or the largest most destructive
slugs will hump right over it without touching the copper.

Six inch copper? Good Lord, what kind of slugs are we having here?
Something
big enough to "hump" over that is big enough to eat! Maybe a night
watchman
with a shotgun is required. (is there a hunting season?)

My parents have some species of slug in their area that is larger than your
thumb! The slugs I have are so tiny that you can hardly find them which
makes them really hard to eliminate by picking them off by hand.
