You are aiming to apply a light but even coverage across the whole area. We suggest walking at an even but moderate pace while applying the product from side to side.


  • Shake well before use.
  • Avoid applying near waterways and drains.
  • Do not apply before heavy rains.
  • Apply only to lawns and garden areas.
  • Avoid applying to paths, pavers, render, etc.
  • In the event of some overspray rinse with water immediately.
  • Please retain spray nozzle for subsequent applications.

Note: The rate of water flow from the tap does impact the rate of product application. We recommend starting with a low water pressure to ensure equal distribution of product across the whole area.
