Common Silverfish redux

Summer reruns. Here’s an enhanced version (more fun silverfish facts) of an episode that first aired in the spring of 2009.


Silverfish are spindle/carrot-shaped, flat and gray with a metallic “finish.” Your common, household silverfish, lives in cool, damp places, feeding on house dust, bits of dried vegetation, small insect body parts that get restaurants in trouble, sawdust, and starch, which it gleans from wallpaper paste and from the glues used in book-binding.

Silverfish (Family Tricholepidiidae)

Silverfish are spindle/carrot-shaped, flat and gray with a metallic “finish.” Your common, household silverfish, lives in cool, damp places, feeding on house dust, bits of dried vegetation, small insect body parts that get restaurants in trouble, sawdust, and starch, which it gleans from wallpaper paste and from the glues used in book-binding. The female lays her eggs in cracks and crevices. If she picks a hospitable microclimate, her eggs will hatch looking like mini adults and grow slowly. Silverfish live several years and molt more than a dozen times.
