How to Apply

CyLence® Pour-On Insecticide is a ready-to-use solution. Apply the required amount of solution from a graduated syringe, cylinder or standard sized dipper directly along the top of the back and top of the head of the animal.

The dose applied depends on the weight of each animal. The following table shows the correct amount to apply. Note: Due to the small amount of material required, care must be taken to apply the correct dose.

  • Treatment for flies can be repeated as needed to a maximum of 3 applications per year, but not more than once every 3 weeks.
  • For optimal lice control, an initial application followed by a second treatment 3 weeks later is recommended.
    • Biting lice (Mallophaga) will usually be eliminated within one week after the first treatment.
    • Sucking lice (Anoplura) may persist on a few animals after the second treatment.
  • Leave a minimum interval of 3 weeks between applications for fly control and louse control.
