You've obviously never had O. fulgidas. Traps aren't efficient enough, you'll never catch one with tongs.
I've had fulgidas in two tanks. Tank #1- I essentially hit reset- drained tank, replaced all rock and sand. cleaned out sump and plumbing. Fulgida free but a massive pita and somewhat expensive replacing all sand and rock.
Tank #2- Added 2 C regius and let them hunt. The first couple of mornings the cones were covered in the fulgidas tell tale mucus. Thought the worms got the upper hand on the snail. Put on gloves to remove it and sure enough the cone was still kicking. They've been in there a few months now. Haven't seen a single fulgida during red light inspections and traps are pulling nothing but E. complanata.

It's not getting through these gloves--
