Under the Local Land Services Act 2013, landholders have a legal obligation to report any of the three declared plague locust species (Australian plague, spur-throated and migratory locusts) to their Local Land Services office.

Landholders also have an obligation to eradicate locusts on their property.

Impact of plague locust

Plague locust species, if not controlled, cause significant damage to crops and pastures by consuming all in their path.

Serious infestations of plague locusts cause significant economic loss to affected landholders.

Plague locust control

It’s vital that ground-control activities for locusts are carried out at the banding stage (third instar) to save time and reduce the need for a second spray for later hatching locusts.

This will also reduce the risk of residue concerns associated with the chemical application.

It’s also extremely important that the situation is monitored closely before and after control activities.

A number of pesticides are registered for the control of spur-throated locusts. Your local Biosecurity Officer can advise on eradication methods and provide insecticide to ratepayers. All control should be undertaken as per the label or off label permit instructions.

Effective control of swarms is mostly done by aerial spraying, targeted at juvenile adults while roosting in the evening or early morning.

For more information on pest species and biosecurity, visit Pestsmart and the Department of Primary Industries.

Otherwise, please contact your local Biosecurity Officer if you require locust pest animal management advice.

Regional Strategic Pest Animal Management Plans

We've worked with regional pest animal committees and the community to develop regional strategic pest animal management plans in each of our 11 Local Land Services regions.

Your Regional Strategic Pest Animal Management Plans will tell you what priority pest animal pest animals you need to manage and how.
