Why we love it
  • Fast-acting and effective formula.

Main Highlights
  • 🎯 KILLS SILVERFISH ON CONTACT — IMMEDIATE KNOCKDOWN — Fast-acting formula eliminates silverfish the moment they cross a treated surface. Effective against adults, eggs and nymphs — disrupting the full infestation cycle, not just the adults you can see. Spray directly onto silverfish and into crevices, cracks and skirting boards for instant results.
  • 🚿 TARGETS EVERY SILVERFISH HOTSPOT IN YOUR HOME — Silverfish breed in damp, dark areas: bathroom grout lines, under kitchen sinks, behind toilet cisterns, basements, loft spaces, and anywhere books, wallpaper or cardboard are stored. Apply along skirting boards, into wall cavities, behind radiators and under appliances. One 500ml bottle covers a full house with multiple treatments.
  • 🔒 UP TO 3 MONTHS PROTECTION PER TREATMENT — After application, the active formula leaves an invisible residual barrier on treated surfaces that continues eliminating silverfish for up to 3 months — no need for constant reapplication. Non-staining on tiles, grout, wood, wallpaper and skirting boards. No sticky residue, no visible marks — just discreet, long-lasting protection throughout your home.
  • 🌿 ODOURLESS ONCE DRY — PLANT-DERIVED ACTIVE INGREDIENT — Formula dries quickly with no chemical smell, no sticky film and no staining. Active ingredient derived from chrysanthemum flowers (natural pyrethrin) — plant-based pest control trusted by professionals for decades. Safe to use in bathrooms, kitchens and living spaces once fully dry. Keep children and pets away until dry.
  • ✅ PRECISION NOZZLE — REACHES EVERY HIDING SPOT — Fine-mist nozzle delivers controlled, targeted spray into tight crevices, grout lines, gaps behind fixtures and hard-to-reach corners where silverfish breed. 500ml provides extensive coverage for multiple rooms and repeat treatments throughout the season. Backed by Pest Strike's satisfaction guarantee — contact us anytime if you need support.
