Earwigs
Earwigs are recognizable by their pair of pincers at the tip of their abdomen, which can look a bit alarming but rarely pose a threat to people. They gravitate toward damp, dark areas, making the bathroom a suitable spot to hide. If you’d rather not stumble upon one in the middle of the night, try reducing humidity with a dehumidifier, opening windows to let fresh air circulate, and wiping up spills or excess water. Inspect and seal any cracks or gaps, especially around exterior walls, to keep earwigs from sneaking in. Maintaining a dry, well-sealed bathroom will make them less likely to stick around.
