Its proprietary PolyZone technology binds the active ingredient to treated surfaces, protecting it from weather, wash-off, UV exposure and abrasion, helping maintain efficacy even under challenging environmental conditions. Formulated with deltamethrin, K‑Othrine® PolyZone delivers extended residual protection on a wide range of surfaces, making it particularly suitable for vector control programmes in regions where conventional residual insecticides may lose effectiveness more rapidly.

Extended residual control

• Provides more than 6 months of residual activity indoors and up to 3 months outdoors against susceptible mosquito populations.

PolyZone™ technology

• Proprietary polymer technology protects deltamethrin from wash-off, UV degradation, dust and abrasion, supporting longer-lasting performance.

Reduced retreatments

• Long-lasting efficacy can help reduce application frequency and improve operational efficiency.

Ideal for harsh environments

• Maintains effectiveness on porous and difficult surfaces, making it suitable for challenging climatic conditions.
