Silverfish Habitat

As their name implies, silverfish love to live in warm, humid areas such as bathrooms and laundry rooms. They often hide behind baseboards, moldings, and ledges. In homes with crawl spaces or unfinished basements, silverfish may be found in the upper corners of the basement where there is a source of moisture from seeping water pipes, air conditioning condensate, dehumidifiers, and leaking water heaters. Silverfish can also flourish in damp crawl spaces, cracks between masonry bricks and concrete foundations, under moist carpeting or rugs, and anywhere insulation material has become wet. Areas, where spilled liquids such as soft drinks have been left undisturbed for a long time, are favorite hiding places. Silverfish may also be seen in bookstores, libraries, and homes where there are stacks of newspapers or magazines for their scavenging pleasure.
