Silverfish have a very long lifespan, which can be up to 8 years if the conditions are appropriate. A Silverfish female can lay 100 eggs in one lifetime; she will lay these eggs either singly or in small clusters of two or three. When the Silverfish first hatches it is white, and smaller than the adult, its color will change in four to six weeks, and it will reach full maturity in three to twenty four months. Unlike many insects this Silverfish continues to molt even after becoming an adult.
The Silverfish prefers cool, dark, and damp areas to reside such as basements and laundry rooms. Sometimes, they are found in a bathtubs, sinks or washbasins, unable to climb out. They eat a variety of materials in a home that after a long period of time could cause a problem, such as glue, wallpaper paste, book bindings, paper, photographs, and starch in clothing, cotton, linen, rayon fabrics, wheat flour, cereals, dried meats, leather and even dead insects. Due to the low reproduction rate of the Silverfish, it takes a long time for a large infestation to occur, but if one was to notice many Silverfish in their home, it is important to take care of the problem immediately.
