Signs You Have Silverfish
- Small irregular feeding marks on paper, books and photos
- Yellow stains or small dark droppings on stored paper and fabric
- Live silverfish darting away when lights are turned on in bathrooms or laundries
- Holes or grazing on natural-fibre clothing in wardrobes
- Shed skins ( translucent scales) in dark, undisturbed areas
Why Silverfish Become a Problem
Silverfish damage irreplaceable books, photographs, documents and natural-fibre clothing. They thrive in damp, poorly ventilated areas and can persist for years in roof voids and subfloors, gradually expanding into living areas.
Where We Commonly Find Them
- Roof voids and ceilings
- Subfloors
- Bathrooms, laundries and toilets
- Wardrobes and linen cupboards
- Bookshelves and storage boxes
- Behind wallpaper and skirting
How We Inspect for Silverfish
We inspect roof voids and subfloors for activity and moisture, check wardrobes and bookshelves for feeding damage, and identify the damp conditions — leaking pipes, poor ventilation or condensation — that silverfish require to survive.
How Silverfish Treatment Works
Treatment applies insecticidal dust to roof voids and subfloors, residual spray to skirting, cupboards and damp areas, and targeted treatment to wardrobes and storage zones. We also advise on reducing the moisture and humidity that silverfish depend on.
Areas We Treat
- Roof void
- Subfloor
- Bathrooms and laundries
- Wardrobes and linen cupboards
- Bookshelves and storage areas
- Skirting and architraves
How Long Treatment Takes
A silverfish treatment takes 45–75 minutes. Because silverfish are long-lived and eggs hatch over weeks, residual protection is designed to remain active for several weeks after treatment.
What to Do Before Treatment
Clear access to roof void and subfloor manholes, remove items from wardrobe floors where possible, and note any areas where you have seen silverfish or noticed dampness.
What to Do After Treatment
Do not wipe treated skirting or cupboard interiors for at least two weeks, ventilate treated areas, and address any moisture sources we identified during inspection.
When Follow-Up Treatment May Be Required
A follow-up at 3–4 weeks is recommended for established infestations, as silverfish eggs are resistant and newly hatched nymphs may emerge after the initial treatment.
Silverfish Treatment Cost
Silverfish treatment cost depends on property size and whether roof void, subfloor and internal areas all require treatment. Request an accurate quote for your property.
Prevention Advice
- Reduce humidity with ventilation and dehumidifiers in damp areas
- Fix leaking pipes and seal gaps around plumbing
- Store books and photos in sealed plastic containers
- Keep wardrobes ventilated and avoid overpacking
- Inspect second-hand books and furniture before bringing them inside
