Yellow Crazy Ants

A yellow crazy antYellow crazy ants are a critical biosecurity priority in the Townsville local government area (LGA), with over twenty known infestations. You should report any ants that you suspect to be yellow crazy ants.

Local Voices, Lasting Impact

Since its launch in November 2023, the Townsville Yellow Crazy Ant Management Program (TYCAMP) has made significant progress in protecting the region from one of the world’s most destructive invasive species.

Yellow crazy ants are listed among the world’s 100 worst invasive alien species and pose a serious threat to Townsville’s biodiversity, industries, and community assets. In response, TYCAMP was established through a $12.8 million, four-year partnership between the Department of Primary Industries, Townsville City Council, the Australian Government, and the Queensland Government.

To date (December 2025), the program has:

  • Identified 41 infestations across the Townsville Local Government Area,
  • Treated over 4,766 hectares using a combination of aerial (helicopter and drone) and ground-based applications,
  • Deployed more than 8,700 overnight lure stations to detect ant activity,
  • Monitored 77 sites to track treatment effectiveness and reinfestation risks,
  • Used ANTOFF as the primary insecticide, selected for its targeted impact and environmental safety.

Beyond field operations, the TYCAMP team has worked closely with affected residents across 10+ suburbs to tailor treatment options to individual property needs, while also raising awareness about the ongoing biosecurity risk.

TYCAMP has laid a strong foundation for long-term biosecurity success, and the team remains committed to protecting Townsville’s environment and community from the ongoing threat of yellow crazy ants.

About Yellow Crazy Ants

Yellow crazy ants are listed as one of the world's 100 worst invasive alien species, and one of the world’s worst tramp ants. Their true origin is unknown due to their rapid colonisation of countries around the world, however experts suspect yellow crazy ants originate from South-East Asia.
