Edmonton - treatment of yellow crazy ants

The yellow crazy ant infestation at Edmonton was first detected in 2001 and has become established over about 600ha in the Bentley Park, Edmonton and Mount Peter areas south of Cairns. Yellow crazy ants were detected within the World Heritage Area and Little Mulgrave National Park in 2012 and now cover up to 30ha within these protected areas.

Consent forms

As part of the treatment program we will need the cooperation of local residents. You have probably already have received some information about yellow crazy ants been asked to fill out a consent form. These forms allow a pest controller to enter your property to lay ant baits when required.

The consent forms also allow you to ask the pest controller to contact you before treatments to manage locked gates and dangerous pets.

You can download a consent form for yellow crazy ants here if you have not yet filled one out.

Helicopter baiting

Some landholders of larger properties may be asked if they consent to allow helicopters used for baiting tofly within 10m of their house (while remaining about 50 feet above the ground).

The Wet Tropics Management Authority has received $2M funding from the Australian Government to eradicate yellow crazy ants from the Edmonton area and surrounds. The program will run for five years, from 2013 to 2018. Details of the eradication program are listed below.
 

Delimitation of the crazy ant infestation

  • March 2016 - The Natural Asset Management Advisory Committee Taskforce again mapped the western boundary of the yellow crazy ant Infestation. There was no expansion of the yellow crazy ants on the western boundary.

They found no significant expansion of the ants over the past year. Participants reported that the numbers of yellow crazy ants were significantly less than a year ago.

  • Many thanks to all the participants from FNQ Regional Organisation of Councils, local governments from across the Wet Tropics, Queensland Parks and Wildlife Service, Conservation Volunmteers Australia, Biosecurity Queensland, Jarragun NRM, Djunbunji Land and Sea Rangers and Gunggandji Rangers.
