Fire ants

Aerial fire ant treatment

The distribution of bait by helicopter is the most effective way of eradicating fire ants on larger properties. By using helicopters, the program can cover hundreds of thousands of hectares each treatment season.

The bait used is safe for humans and animals and livestock are generally unconcerned by the helicopters.

Treatment process

Before we carry out aerial bait treatment we inform residents of the planned treatment dates – which are weather dependent.

Treatment can occur between 7am and 4pm, seven days a week and several rounds of bait is required.

Each site is individually assessed before treatment to take account of factors like crops or livestock. Sites that are not suitable for treatment by helicopter will have bait distributed by program staff on foot and/or all-terrain vehicle.

If your property has animals, crops or other features you think we should be aware of you can submit an online property information form.

We use highly-experienced pilots who continually observe on-ground behaviour of horses, cattle and other livestock during the treatment. If issues arise they will fly the helicopter away from the area.

Program staff are also located on the ground nearby and will alert the pilots to any issues. Signage will be erected in the surrounding area to notify residents of the aerial baiting taking place.

Bait

Fire ant bait is made up of corn grit soaked in soybean oil and infused with either an insect growth regulator (IGR) or fast-acting insecticide and is thinly distributed across backyards and garden areas as well as parklands and paddocks. The program uses a range of baits, dependent on the treatment area, nest type and location.

All products are safe to humans and most animals when used by the program according to the conditions on the relevant product labels and the Australian Pesticides and Veterinary Medicines Authority (APVMA).

It is placed in hoppers on the side of the helicopter and released over the target area.

Free-range poultry will require containment away from the baiting during and after treatment for 24 hours to ensure any fire ants in the vicinity can gather the bait before the chickens consume it.

Other animals, like cattle and horses, do not need to be relocated for the treatment.

Once the baiting has been carried out it’s important that you do not water, mow or disturb your lawn, gardens and paddocks for at least 24 hours, preferably 48 hours.

The Biosecurity Act and accessing properties

Under the Biosecurity Act 2014, program officers are authorised to enter properties to undertake treatment for fire ants. Residents cannot refuse access to their property or obstruct our officers carrying out their work.

Read officers accessing your property for more information.
