Capable of thriving in most climates, silverfish prefer to dwell in dark, damp areas such as basements, attics, kitchens and bathrooms. They are especially attracted to paper and damp clothing. Commonly found in stored boxes in garages and sheds.
Homeowners often transport silverfish indoors unknowingly. When brought inside the home, cardboard boxes and plastic containers recently stored in infested areas can allow the pests to spread.
Warm and moist spaces, like basements and crawl spaces, attract silverfish. The pests will enter homes through foundation cracks, torn screens, or gaps around doors. Leaving dirty dishes out in the open will also lure silverfish indoors.
