Treatment & Prevention
Prevention:
Certain molecules repel sandflies, such as permethrin and deltamethrin. Permethrin, used as spot-on, depending on concentration, will repel sandflies for 2 to 3 weeks. Deltamethrin in pet collars is effective for several months. The effectiveness will depend on the initial concentration, the mode of application (it is more effective with pet collars), the animal, its lifestyle and the climate (wind, temperature, humidity).
