Aerial spraying is a way to tackle invasive weeds when it’s not possible to control them from the ground with people, tractors or machinery.

Sometimes spraying is the most effective and efficient way to control invasive weeds like gorse, lupin, thistles and blackberry.

Safe spraying

We have invested a lot of time into refining our protocols and procedures to make sure spraying is done safely and carried out in the best interest of the community and the environment. When deciding on a ground or aerial spraying programme we carefully consider:

  • What invasive weeds we are wanting to control
  • Where they are
  • What is the cost of control
  • How close the weeds are to water, native plants or forest, agricultural land and houses.

Watch our video series below which explains all you need to know about aerial spraying, including how and why we do it.
