no one seems to ever mention diatomaceous earth as a mechanical pest detterent for snails and slugs. Its not fancy enough I guess.
I have small snails on some other plants I notice like the antheriums. That why they stay over yonder by themselves. Wondered why thems nails didnt like my orchids. BEC I use diatomaceous earth in my orchids, dust and all. Seems the sharp edges of the silica cuts the snails and slugs up and then they start to leak and die. They dont like to leak out and die. All of your remedies seem fine except the bombing of your plants with harsh chemicals. There is a better way. Says that DE is good for lots of pests and crawlies around the house and garden also. Orchids seem to like the diatomaceous earth. Its just not very fancy and requires no PHD to apply
