Recognizable by the pincers on their rear end, earwigs might look intimidating, but they’re harmless to humans. They prefer dark, damp spaces, making bathrooms a prime hiding spot. To avoid surprise encounters, keep the room well-ventilated, use a dehumidifier, and wipe up excess water. Check for and seal gaps, especially along exterior walls, to stop them from sneaking inside. Keeping your bathroom dry and well-sealed will discourage them from settling in.
Centipedes

With their many legs and lightning-fast movements, centipedes can be unsettling to spot darting across the floor. However, they feed on other insects, meaning their presence often signals a bigger pest problem. The best way to prevent them is to lower humidity—run an exhaust fan, open a window after showers, and fix leaks. Sealing cracks along baseboards and plumbing fixtures will also limit their access.
Psocids (Booklice)

Psocids, commonly known as booklice, are tiny insects that thrive in moisture-rich areas with mold or mildew. Bathrooms with poor ventilation are their favorite hiding spots, as they feed on the fungi that develop on damp surfaces. To keep them out, improve air circulation by running a fan during and after showers, and clean regularly with a mild disinfectant. If mold starts forming, remove it immediately—without their main food source, psocids will disappear.
Pill Bugs (Roly-Polies)

Pill bugs, or roly-polies, typically live outdoors in damp soil, but they can wander into bathrooms if they find a humid environment inside. Since they need constant moisture to survive, a wet bathroom is a perfect retreat. To encourage them to leave, keep the space as dry as possible by repairing leaks and wiping up puddles. Blocking entry points around doors and windows will also prevent them from sneaking in. While harmless, they’re not exactly a welcome sight near your shower.
Springtails

Springtails are tiny insects named for their ability to jump when disturbed. They love high-humidity areas and feed on mold, algae, and organic debris. If your sink or tub drain has residue, you may spot these tiny jumpers around. The best way to keep them away is to reduce moisture—use an exhaust fan, dry off surfaces, and clean regularly. Make sure to scrub damp spots like bath mats and shower curtains, as these can be their favorite hangouts.
Keeping Your Bathroom Bug-Free
A pest-free bathroom is within reach if you maintain a simple yet effective cleaning routine. Regularly wiping down surfaces, fixing leaks, and ensuring proper ventilation will go a long way. Avoid leaving damp towels and bath mats piled up, as these create the perfect breeding ground for bugs. Also, inspect for cracks and seal them with caulk to block entry points. A little effort in maintenance can keep your bathroom a peaceful, pest-free space—no six-legged or eight-legged intruders allowed!
