What to do with snails indoors?

[greenochre]

I caught this little guy alive and kicking on one of my orchids today. I have a lot of plants crowded on a shelf in my room with LED lights and a humidifier, and, obviously, where is one, there are many.

I used to think I had thrips infestation, is it possible it was a snails issue all the way? Symptoms included yellowed/browned leaves, small holes and strikes on leaves, calatheas, orchids and ferns are affected more than other plants.

What should I do?
