When are Silverfish Most Common?
Silverfish are active all year but are most noticeable in damp, dark places such as bathrooms, kitchens, and utility rooms. Homes in Bourton-on-the-Water and across the Cotswolds with older stone walls or poor ventilation are particularly at risk.
Signs of a Silverfish Problem
Look for tiny, silvery-grey insects darting quickly when disturbed, especially at night. You may also notice irregular holes in wallpaper, book bindings, or cardboard boxes. Shed skins and yellowish stains around damp skirting boards or cupboards are other tell-tale indicators.
Damage and Risks caused by Silverfish
Silverfish don’t spread disease, but they damage books, fabrics, wallpaper, and stored papers. In heritage homes around the Cotswolds, they can cause ongoing nuisance by nibbling irreplaceable items and delicate finishes. Their presence also signals high humidity, which can lead to further pest or mould problems.
When to Call Pest Control
If you notice recurring silverfish despite cleaning and ventilation efforts, it’s time to bring in professional pest control. Persistent infestations can spread across rooms and cause hidden damage. A local Cotswold-based controller will quickly identify the source and apply safe treatments.
How We Remove Silverfish
A technician will assess damp areas, apply targeted insecticidal sprays or dusts, and recommend moisture control measures. Treatment is usually completed in one or two visits, depending on the severity. Silverfish can be tricky to eliminate fully, so follow-up monitoring is often advised.
How to Stop Silverfish Coming Back
Keep humidity levels low by improving ventilation, using dehumidifiers, and repairing leaks. Store papers and clothes in airtight containers, and vacuum regularly behind skirting boards and under furniture. Sealing cracks in walls and floors also helps keep these fast-moving insects out.
