Product Description
Dimefluthrin is a new pyrethroid hygienic insecticide, delivering strong efficacy against mosquitoes resistant to allethrin and prallethrin. It features favorable safety to humans and low environmental pollution under correct application, and its formulation dosage can reach as low as 0.015%.
Currently, the GC‑ECD method established by Sumitomo Chemical Co., Ltd. (Japan) is widely used to test dimefluthrin in mosquito coils. Nevertheless, its complicated sample pretreatment makes it necessary to develop a more practical analytical method for mass production.

Product Application
Tetrafluoromethrin is a synthetic pyrethroid insecticide known for its strong insecticidal properties. It is particularly effective against mosquitoes, including certain strains that have developed resistance to conventional insecticides such as allethrin and pyrethrin. Due to its rapid insecticidal action, it is commonly used in mosquito control and household pest control products.
