Silverfish are ancient, nocturnal insects that thrive in dark, high-humidity spaces like bathrooms and basements. Spotting one usually means you are seeing the “scouts of a much larger, hidden population” already living behind your drywall.
They do not bite or transmit diseases, but they are “fundamentally destructive to your lifestyle.” They feast on cellulose, glue, and starches found in book bindings, wallpaper, and clothing, and their shed skins can act as “potent allergens.”
To eliminate them, you must change their environment by lowering humidity, fixing leaks, and clearing out paper clutter. Sealing cracks and using natural weapons like diatomaceous earth will help you “evict these ancient guests for good.”
