Other planned events: Notice of 1080 ongoing program

NSW National Parks and Wildlife Service (NPWS) is conducting an ongoing ground baiting program from Monday 23rd September 2024 to Tuesday 23rd September 2025. The operation will use a Felixer containing 1080 (sodium fluoroacetate) poison for the control of feral cats, and approved meat baits, meat bait products, and Canid Pest Ejectors (CPE) for the control of foxes and wild dogs.

The program will be conducted in Nattai National Park.

Signs will be placed at the entry to the baiting location. Domestic pets are not permitted in NSW National Parks managed lands. Pets and working dogs may be affected (1080 is lethal to cats and dogs). Pets and working dogs must be restrained or muzzled in the vicinity and must not enter the baiting location. In the event of accidental poisoning seek immediate veterinary assistance.
