Life Cycle of Silverfish

Silverfish are little, wingless insects that can measure up to an inch long. The get their name from their fish-like movements, and commonly are bluish or gray. Contrary to what many people think, they don't bite but they can ruin fabrics, wallpaper, books and other household items. To prevent silverfish, it helps to understand their life cycle.

The Reproduction Stage

The silverfish has an extensive mating ritual. It consists of three phases and can last up to 30 minutes. In the first phase, the male and female perform a dance in which they repeatedly touch antennae. In the second phase, the female chases after the male. Once she catches him, the final phase begins as the male releases his sperm to the female. Later, the female will release her eggs. The resulting baby silverfish are white.


During the growth stage, silverfish eat many different things. They are especially attracted to starchy foods and some adhesives. They may eat book bindings, photos, textiles, sugar and even human hair, but they are also known to survive for up to a year without eating. Silverfish can be found in cool and damp places around the home. The bathroom is a popular spot for silverfish, especially around sinks, baths and showers.
