Why am I finding silverfish in my bathtub and drains?
Silverfish crawl up through dry or infrequently used drain pipes to feed on organic debris and find the moisture they need. This keeps happening even in clean homes because high ambient humidity and damp bathroom surfaces create an ideal breeding ground that repels standard cleaning efforts.
