On reading the replies on the post regarding Raffy and slugs I also recently started get silver slug trails mainly on the door mat but also slithering onto the kitchen carpet but can't for the life of me find any slugs or figure out how they are getting in it's a close fitting Upvc door and the can hardly dash in when it's left open can they also the trails don't seem to have a start point they appear in the middle of the rug just wondering how common this seems to be.
