Ever wonder why bugs are drawn to your bathroom? The combination of moisture, warmth, and easy access to water makes it an inviting space for pests seeking relief from dry conditions.

Here are ten common bathroom pests you may encounter, along with practical tips to keep them away.

Silverfish

Silverfish are small, shiny insects with a wriggling, fish-like movement. They thrive in bathrooms due to the humidity and often feed on starchy substances like paper or shampoo residue. To discourage them, keep your bathroom dry by using the exhaust fan or opening a window. Clean up any damp paper products, such as peeling wallpaper or soggy cardboard boxes, as silverfish are attracted to them. Sealing cracks around baseboards and pipes can also limit their hiding spots.

Cockroaches

Cockroaches are drawn to moisture and food sources, which bathrooms can provide if water is left standing or soap scum builds up. These hardy insects can enter through drains or small gaps under doors, so sealing potential entry points is crucial. Establish a thorough cleaning routine that includes wiping surfaces dry and fixing leaks to make the bathroom less appealing. If you’ve already seen cockroaches, consider using safe gel baits or traps near their likely hideouts.

Drain Flies

Drain flies, also known as moth flies, are tiny, fuzzy-winged insects that hover around sinks or tubs. They breed in the slimy residue inside drains and pipes. To get rid of them, scrub your drains with a sturdy brush and flush them with boiling water or a safe cleaning solution. Keep surfaces dry and regularly remove soap scum to prevent creating an environment for drain flies to reproduce.

Spiders

Though spiders are arachnids, not insects, they’re often grouped with common bathroom pests. They typically enter in search of moisture or to hunt other small insects. While spiders can be helpful by capturing pests, many people prefer not to share the bathroom with them. Regularly clean corners, check behind cabinets, and avoid leaving damp towels lying around. For an extra deterrent, try spraying peppermint oil in corners, as many spiders dislike strong scents.

Ants

Ants are typically drawn to bathrooms when they’re searching for water or food scraps, like sugar residue from hair products or discarded wrappers. To make your bathroom less appealing, fix leaks, store products in closed cabinets, and seal small crevices around windows, vents, and plumbing. If ants persist, place baits in discreet spots like behind the toilet or under the sink—but be sure to keep them out of reach of children and pets.

Earwigs

Earwigs, known for the pincers at the end of their abdomen, are attracted to damp, dark places like bathrooms. They are harmless but unsettling to find. To keep them at bay, reduce humidity by using a dehumidifier, open windows for air circulation, and wipe up excess water. Seal cracks or gaps, especially around exterior walls, to prevent them from sneaking in.

Centipedes

Centipedes are easily identified by their numerous legs and fast movements. Though they help by feeding on other pests, they can be unsettling to spot in the bathroom. To deter them, reduce moisture by running the exhaust fan or opening a window after showers. Sealing gaps around plumbing lines and baseboards will also help prevent them from entering.

Psocids (Booklice)

Psocids, or booklice, are tiny, soft-bodied insects that thrive in moist environments with mold and mildew. They’re particularly common in bathrooms without adequate ventilation. To keep them away, focus on controlling moisture by running a fan during showers or leaving the door open afterward to improve airflow. Regular cleaning with a mild disinfectant can also help remove mold, which is their primary food source.

Pill Bugs (Roly-Polies)

Pill bugs, also known as roly-polies, typically live outdoors in damp soil but can find their way into bathrooms in search of moisture. A perpetually damp bathroom is a perfect hideout for them. To keep pill bugs out, fix leaks, wipe up standing water, and seal gaps around windows and doors. Though harmless, it’s not pleasant to find them rolling into a ball near your bathtub.

Springtails

Springtails are tiny insects that can jump when disturbed. They’re drawn to bathrooms with high humidity, where they feed on mold, algae, and organic debris. To prevent them, keep surfaces clean and dry, and use an exhaust fan after showers. Periodically clean shower curtains or bath mats that stay damp, as these are prime spots for springtails.

Prevention Tips for a Bug-Free Bathroom

To maintain a bug-free bathroom, stick to a consistent cleaning routine. Simple actions like wiping down counters, fixing leaks, and ensuring proper ventilation can make a significant difference. Avoid leaving damp towels or bath mats in piles, as they create the perfect environment for pests. Inspect for cracks where bugs might enter and use caulk or sealant to block them. With a little proactive care, your bathroom will remain a peaceful, bug-free retreat.
