I have a silverfish infestation in my house. I don't see them often, but they have been eating at some of my old book covers and paper products. My old house electrical permit which sits above the panel has a lot of damage now, but ten years ago when I moved into this old house it was fine. I have a lot of junk like old books, records and such in the house, and car parts, electrical parts etc. in cardboard boxes. But things are pretty clean in general. These pests seem to like paper and not food scraps- I don't see them in the kitchen, but occasionally trapped in the bathtub and more in the basement. I have one or two glass doored bookcases in which I put blocks of camphor which seems to keep them away. Any way to kill these varmints before they ruin my hundred year old books? Maybe I need to banish my cat and get mice to eat them?
