Funny I came across this post! I was cutting fabric yesterday for a quilt and was into the starching and ironing and all I could think of was silverfish! Don't have any, and have not seen any for years since we put up wallpaper in an older home (they love starch!). With all the starching going on, I kept thinking about those tiny things scooting all over. I have a large piece of cardboard put up behind a door and laid on the floor that I hold up the fabric to when starching so it does not get all over. We keep a dehumidifier going 3 seasons out of the year to keep dampness out of the house. We have asthma in the family, so have to keep it dry anyway. Possible we don't have the silverfish because of this. At least I am not seeing them if we do....
