Ever wonder why insects are drawn to your bathroom in the first place? Moisture, warmth, and easy access to water create a cozy habitat for pests seeking relief from dry conditions. Whether you’ve noticed something creeping along the tub or spotted a skittering shape disappearing behind the toilet, it’s helpful to know which bugs thrive in this space—and, more importantly, how to send them packing. Below are ten common bathroom bugs you may encounter, along with practical tips to keep these unwelcome guests at bay.
Silverfish

Silverfish are small, shiny insects with a wriggling, fish-like movement. They love bathrooms because of the humidity, and they’ll often feed on starchy substances like paper or shampoo residue. To discourage their presence, keep your bathroom as dry as possible by running the exhaust fan or opening a window. If you have peeling wallpaper or soggy cardboard boxes lying around, tidy those up, since silverfish appreciate damp paper products. Sealing cracks along baseboards and around pipes can also limit their hiding places, reducing the likelihood of spotting them flitting across the floor.
