What are the rules?

Advisory

Council does not enforce the control of advisory species. It is landowner/occupier responsibility to manage these pests. Council may provide advice on how to manage or control advisory species if required.

How do you get rid of them?

Insecticide needs to be strategic and well-coordinated or results will be limited.

Professional pest controllers are recommended.

Wasp nests are sprayed at dusk when the majority of wasps are back at the nest.

 

CAUTION: When using insecticide please READ THE LABEL thoroughly to ensure that all instructions and safety requirements are followed.
