| Product description | A highly active Type II synthetic pyrethroid insecticide and acaricide. It acts on the insect nervous system by modulating sodium channels, leading to paralysis and death (knockdown effect). It has strong contact and stomach action but no systemic or fumigant activity. It is known for its rapid knockdown, broad spectrum of activity, and long residual control. It is also highly irritant and repellent to insects. |
