I was reading "slugs- why not salt?" and have a few sugestions to contemplate over winter.
If you can avoid it, do not use slug pellets or deadline. These contain poisons that are harmful to kids, pets, birds and beneficial insects. It kinda defeats the purpose of being out enjoying nature.
A harmless and lasting technique is utilizing copper. When a slimy slug comes in contact with copper [metal, not spray] there is an electrical charge that scares off or kills them. Copper banding is commercially available for this purpose [Lee Valley and others]. It goes around container rims or raised beds. Ensure there are no slugs within your barrier, no more will cross into the area[or out]. Older pennies [that actually contain copper] strewn about do the job as well. This works in a paved area with containers. I've experimented directly in the garden, sprinkling them around the base of hostas in early spring. I've seen slimetrails working their way around the pennies. If they get covered in dirt, they are no longer effective.
An organic solution is eggshells. When you're done with the egg [making slug fritters from the sounds of some of you people], rinse and let dry. When you have enough of them, crush them and sprinkle around the base of your susceptible plants. Slugs don't like travelling over anything sharp. This is completely harmless to everyone.
If a firmer approach is necessary, break out the Diamataceous Earth. I have been using and recommending this stuff for about 10 years. Out here on the Wet Coast slugs are plentiful and huge.[I've contemplated rigging up a harness and having them pull a wagon] This product is available from all sorts of manufacturers. It'll be called crawling bug killer, ant killer, various names. It comes in a cylindrical container with a nozzle on top. Check the labels for the ingredient percentage to get your best deal - it varies wildly [anywhere from 80 - 97%].
Diamataceous Earth is comprised of finely ground fossils. It is not a poison, but cuts up and then dehydrates slugs as they travel through it. It is applied as a fine powder and dusted at the base and in the branches of the targetted plants. DE is also used in pool filters because it is tiny but sharp, snagging debris. The only safety consideration is to not breathe in the product when you apply. A light dusting will suffice. As it is organic, it will need to be re-applied after rain. One container will go a long way. I also use this on the earwigs that enjoy chewing on my rhodos. I dust around the bases and a bit through the lower branches. Those little, half-circle holes were driving me mad.
For the non-faint-of-heart, try manual disposal. Psych yourself up, head outside late in the day and look down. Wearing latex gloves will make it easier as the slugs excrete a nastier slime than usual when they think they're being threatened. You'll find a surprising amount of them on just the lawn. I gather them up by the handfulls [EW!!] and then huck them over my hedge onto the road. I always make sure no cars are coming [Can you imagine driving along and then slugs falling on your windshield?] The subsequent traffic pulverizes them.
When you're doing fall cleanup, keep an eye out for tiny white or transluscent balls. You'll find them in groups under boards or dead leaves. Take no prisoners! Squish 'em when you find 'em.
