Before you start dipping them, try moving them down lower in the tank and see if they respond.

But no, an Iodine dip will not kill them assuming you use as directed and don't leave them in longer than you need to.

Check all your equipment. I had a rusting out return pump where my heater touched the cord and ended up exposing copper in to my aquarium. I also had dead snails on the sand bed over night.
