Treatment & Prevention
Certain molecules repel mosquitoes, such as permethrin and deltamethrin. Permethrin, used as spot-on, depending on concentration, will repel mosquitoes up to 4 weeks. Deltamethrin used in pet collars is effective for several months. Effectiveness will depend on the initial concentration, the mode of application (more effective with pet collars), the animal, its lifestyle and the climate (wind, temperature, humidity).
