Small, shiny, wingless insects darting across bathroom tiles are often silverfish, pests drawn to dark, humid spaces. Their presence is unsettling, but the main concern is damage rather than danger to people. Paper, cardboard, wallpaper paste, and some fabrics can become food sources, putting stored belongings at risk when an infestation goes unnoticed. Bathrooms offer ideal conditions, though other damp, undisturbed areas of the house can provide shelter as well.
Start by making those spaces less welcoming: repair leaks, improve ventilation, and use a dehumidifier where needed. Clear away cardboard piles and unnecessary clutter, and keep vulnerable items in sealed containers. Seal cracks around baseboards and pipes to reduce hiding places and movement between rooms. Sticky traps can help reveal where activity is concentrated. If sightings continue despite these measures, contact a pest-control professional. Acting early can protect cherished possessions without treating every stray insect as a household emergency.
