Daisyheadcase, think you are doing everything you can. Im a night patrol guy too and think it's best way.
Copper is effective around pots but slugs and snails inhabit the soil inside the pots too. A pellet or two discreetly placed under leaves then will help. Ditto copper rings in the garden.
Right now it's lupins, delphiniums, heleniums, leucanthemums, salvias, and dahlias that attract slugs in my garden so I target those plants in particular. Get to know what your plants do at certain times of the year...it does help to control these pests. For example, pinks are now starting to flower and soon slugs will turn their attention to these plants. Hostas when flowering attract every slug and snail. it's for that reason that I do not allow some ESP good foliage varieties to flower. (flowering seems to exhaust the hostas' vibrancy anyway)
For me, when I see the first signs of attack, I look carefully around the affected plant and, sure enough, the little blighter is there. Understand your enemy......an old boxing maxim.
Not a good idea to sprinkle salt in the garden I think.......
