They may be small and swift, but if you notice this tiny silver creature scurrying around your home, you could be facing a significant and costly issue. Experts are advising anyone who spots a silverfish in their property to promptly check for dampness.

These shiny, teardrop-shaped insects thrive in moist conditions and are particularly fond of areas with water.

If you see one darting into or out of your skirting boards or crevices around window sills, it’s likely a sign of damp and moisture within your property. If not addressed, dampness can lead to a host of problems, including cracked bricks, rotting joists, decaying plaster, and spreading mould spores. In extreme cases, it can even compromise the structural integrity of the property and impact air quality.

Dampness can result from various factors, such as leaky drainpipes, condensation, ageing damp proofing, or inadequate ventilation, especially in bathrooms or kitchens where water vapour tends to linger. Identifying the cause can be tricky, but the presence of silverfish indoors usually signals that there’s dampness requiring attention.

The sooner signs of dampness are detected, the easier it will be to eradicate the bugs. It recommends looking for indications on walls like wet or damp patches, peeling wallpaper, and flaking plaster.

Other telltale signs include damp and musty smells, rotting wood, and the emergence of mould and mildew on walls, floors, or ceilings.

Among the proposed remedies are utilising a dehumidifier, maintaining good ventilation in your home, inspecting your gutters for leaks, applying damp-proof paint to your walls and, if necessary, engaging a professional to address areas impacted by rising dampness.
