Silverfish are typically .5 inch to .75 inch long with their body tapered at one end, which gives them the fish appearance and commonly known name. Their scientific name, Lepisma Saccharina is based on their diet of starchy food, high in proteins and carbohydrates, and dextrin, which is found in numerous adhesives. Therefore, silverfish may be found in carpet, glues, books, paper, photos, wallpaper, etc. However, they are also known to eat tapestries so they may be found damaging linens, silks, cotton, etc. When first hatched they are white in color and as they get older they become a metallic greyish color with silvery scales and have antennae. Since they are wingless insects, silverfish move by wiggling, again resembling a fish, and are fast enough to outrun many predators.
