Information for Landholders

It is important that any locust activity is reported as soon as possible to your local biosecurity authority or department of primary industries or agriculture.

You can also report locust activity directly to the APLC.

During times of locust control the APLC issues regular Locust Management Advice which gives an update of areas where control is about to or has recently taken place, the insecticides used and the amount sprayed. The APLC will always consult with affected landholders before it implements any locust control and will obtain informed landholder consent prior to the application of any locust control agents.

Landholder locust control

Throughout Australia, primary control of locusts is the responsibility of the landholder. Officers from the relevant state authorities (listed below) are available to provide technical assistance, do inspections and advise on control techniques. These officers should be your first point of contact when reporting locust infestations or making inquiries about locust control.

NSW Local Land Services (LLS) and Department of Primary Industries, Agriculture. LHPA Rangers organise landholder control of bands and distribution of insecticide.

The most effective way for landholders to control locusts is by ground spraying the hoppers when they have formed into dense aggregations called bands. A number of insecticides are registered for locust control but these vary from state to state and over time. The time available for controlling an outbreak of locusts is short. Hoppers take about 5 weeks to develop into swarming adults. Hoppers are much easier to control than swarming adults. The hoppers usually take 1-2 weeks after hatching to form into dense bands suitable for spraying.

Cultivating fields where locusts have laid eggs will have some impact on individual egg beds, but egg laying often occurs in areas where ploughing is not possible (for example, in hard soil along roads or tracks). Although there are a number of natural enemies of locusts such as birds, spiders and insects, these have not been shown to effectively reduce locust numbers when population is increasing rapidly during an outbreak.

What happens if the APLC are controlling in my area?

During a locust outbreak the APLC and state or local biosecurity agency staff may contact or visit you to check locust reports or to obtain consent to undertake control.  Consent is often obtained from many landholders in advance of any anticipated control. However, this is no guarantee that control will be undertaken on your property and you should continue to implement control measures on your property. Control by landholders that may involve provision of insecticide by state or local government or regional biosecurity agency staff, may also involve separate consultation and documentation.

The APLC only carries out control of large areas where locusts are dense enough to be seen from the air. Aerial spraying is only carried out with the permission of landholders. The APLC does not, in accordance with strict national regulations, spray near homesteads, vehicles, stock or dams, beehives or crops being pollinated by bees.  

What can I expect if aerial control is planned on my property?

  • Consultation – You will be contacted or visited by an APLC or state officer to discuss the possible location, date and control agent to be used. In the case of potential APLC control, information on locusts, insecticides and withholding periods will be provided or discussed, along with the existence of any potential activities or organisms which may restrict aerial spraying or the insecticide type.
  • Informed consent document - If you agree to APLC control on your property, you will be asked to sign the APLC Landholder Consultation record PDF PDF [151 KB]. This details the things discussed with you and records your consent for APLC aerial control.
  • Notification near time of control – The timing of any control is subject to weather conditions, available resources and operational planning. You will be contacted again close the actual time of control to make sure circumstances have not changed since your last consultation.
  • Post-control summary information – When control is carried out you will by contacted again to advise you of actual control undertaken. A post control advice document that sets out the details of time, weather conditions, control agent used and includes a map of the area sprayed, will also be provided to you.
