λ-Cyhalothrin solution is widely used as an insecticide in agricultural and residential settings. It effectively controls a broad spectrum of pests, including aphids, beetles, and caterpillars, in crops such as cotton, vegetables, and fruits. In public health, it is applied for mosquito control to reduce the spread of vector-borne diseases like malaria and dengue. Additionally, it is used in pest management for livestock and stored grain protection. The solution is often applied as a spray or treated on surfaces, providing long-lasting residual activity. Proper handling and adherence to safety guidelines are essential to minimize risks to non-target organisms and the environment.
