Swiss Lab Description
STOPPER Silverfish is a ready-to-use spray specifically developed to effectively control silverfish (Lepisma) with both curative and preventive action.
Its formula combines a plant-based pyrethrum flower extract, known for its powerful insecticidal properties, with a blend of essential oils carefully selected for their repellent action. This synergy of plant-based active ingredients ensures immediate and long-lasting effectiveness, eliminating existing insects while limiting their return.
When sprayed directly onto infested or at-risk areas, the product acts in a targeted manner by disrupting the sensory receptors of silverfish. This mechanism leads to their elimination by direct contact and prevents them from moving, feeding, and reproducing. Result: a complete action to quickly regain control of your environment.
The STOPPER spray is particularly suitable for humid, dark, and poorly ventilated areas, which are the preferred habitats of silverfish. It can be used in bathrooms, kitchens, toilets, laundry rooms, as well as on baseboards, joints, cracks, under sinks, door thresholds, window frames, and ventilation openings.
Thanks to its dual action (curative and preventive), STOPPER not only treats an existing infestation quickly but also prevents long-term reinfestation.
Easy to use, the spray fits perfectly into your cleaning routine for effective and effortless protection.
Silverfish mainly thrive in humid environments. To enhance treatment effectiveness, it is recommended to reduce humidity (ventilation, dehumidification), clean sensitive areas regularly, and focus on hiding and transit zones.

FAQ
Silverfish (Lepisma) can enter homes in several ways: through cracks, pipes, ventilation systems or under doors, often from outside or shared building areas. They can also be introduced via boxes, books, papers or stored items.
Attracted by humidity, heat and organic matter (dust, hair, food residues, paper, glue), they easily find favorable conditions indoors. Once established, they can reproduce quickly if conditions are suitable.
They prefer dark, humid and undisturbed areas. Common locations include bathrooms, kitchens, toilets, laundry rooms, and hidden parts of the home.
They hide in cracks, joints, baseboards, under sinks, window frames, ventilation openings, behind furniture or under coverings. They are mainly nocturnal, which explains their discreet presence during the day.
