Silverfish have flattened bodies and most species are clothed in tiny scales.
They are wingless and have chewing-type mouthparts and medium to long thread-like antennae. In Australia, about 5 species of silverfish feed on and often damage books, paper and clothing. Being nocturnal, they mostly hide during the day, becoming more active at night when they seek food. Silverfish are one of the pests treated when carrying out a General Spray.
