A few years ago, I think it was in 2010, we had a very chilly and wet Spring and the Slugs were a real plague that year! I had moved all my Orchids outside in May as I always do, into my 30 foot cage. The Slugs just kept coming until the drier and warm Summer weather somewhere in June arrived, then they stopped essentially over night.
Now I bought Slug bait, they just kept marching right back into my "Screen house".
They were laughing at Beer traps, that didn't work at all.
I collected them every day and dumped them into Salt water, that dissolves them.
I placed slices of Potatoes and Apples around my Orchids and tossed them with the Slugs attached to the underside of those slices every morning into the salt water. That worked quite well. Sprinkling Salt from a Saltshaker was pretty handy too.
I repotted those plants which were in a pot with a rim, because Slugs liked to collect right under that rim. Any Orchid in older bark had to be repotted, since Slugs love to get into decayed Orchid medium. What worked well was using Coconut fiber instead of Bark, it seems the Slugs don't like to crawl through Coconut fiber.
Just a few notes here....surely they can be adapted to any plant!
