The shimmery and slithering silverfish is one bug you never want to see indoors. This pest will feast on fabric, paper, glue, and cardboard boxes. Silverfish are survivors—they even predate the dinosaurs—so it's a challenge to get them out of your home once they're there. You can, however, get rid of them with traps, insecticides, or a natural substance like boric acid or diatomaceous earth. To make sure silverfish stay out, make a few small changes to make your home less hospitable to them. Remove piled up newspapers, junk mail, and old cardboard boxes. Store off-season clothing and supplies in plastic bins, and take your dry goods out of their boxes and store them in containers with tight-fitting lids.
