Snails in the attic
I'm hoping someone might have some ideas. I have snails in my attic. This is a lived in space so really don't want them. I have not seen them but they leave the silver trail. Following that trail I put down salt along the skirting board. Did not help. I then widened the salt area. This helped. Still getting in but only as far as the extra salt. I can see snails getting into a ground floor but an attic?? Not sure what else to do. Nothing harmful as I have pets. Any ideas appreciated.
