Is the aerial application safe?

  Fyfanon ULV Insecticide is safe to use around humans, pets, and wildlife when used according to the product label. Fyfanon is labeled for aerial and ground-application mosquito control and has been an important tool for mosquito control in the U.S., Canada and around the world for 60 years. Once Fyfanon has been applied it immediately begins to break down due to photodegradation, (exposure to sunlight and air) this process only takes a few minutes.


 Fyfanon ULV can be atomized into different sized droplets to target different insects. For mosquitoes the droplet is so small and the application rate is so low it's only visible in perfect lighting. Every year the spray system is calibrated to insure proper droplet size to help reduce harm to non-target insects.


 Fyfanon provides proven, cost-effective control of adult mosquitoes and, as an organophosphate, keeps pyrethroid and pyrethrin insecticides working hard by reducing the chance of resistance development.
