Yes, I have seen threads about this before so I know I am not alone - slugs in my living room!
I like my house but it is in a bad state of repair - waiting for a renovation when I have the money - and so the slugs are not just horrid but also a reminder of the damp that attracts them in the first place. There are no obvious big gaps but they must be squeezing in somehow - or - gasp - breeding somewhere under the floor boards!! In the morning all I can see is a slimy trail on the rug. Can't see the slime where the rug ends so no way of tracing their entry point...
Anyone else had that problem? It's making me depressed. I wish I had a lovely new home with no damp and wildlife sharing it...
