Adult silverfish may live two to eight years. In a lifetime, silverfish females lay about 100 eggs. Depending on the species, silverfish typically reach maturity in three to 24 months. Their populations tend to increase slowly. If a large infestation is present in your house, it is a sign of a longtime infestation.
Sanitation usually provides the best control.
Make sure items, especially fabrics, are clean and free of starch before storing. Keep items in tight-fitting containers, if possible. Removing numerous stacks of papers, boxes, magazines, books and fabrics will also aid in controlling silverfish. Many infestations are localized. Altering the environment by eliminating moisture, sealing cracks and crevices, and removing holiday displays made from food sources can greatly aid in control efforts.
