Behavior, Diet & Habits
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.
Silverfish feed on carbohydrates, particularly sugars and starches. Cellulose, shampoos, glue in books, linen, silk and dead insects may be food sources. Have been found in unopened food packages.
Silverfish undergo love dances prior to mating. Males lay spermatophores, which are taken into the ovipositor of female specimens. Females’ egg numbers and habits vary, depending on species. One species lays a few eggs a day where as another species lays clusters of 2 to 20 eggs.
