As Queensland recovers from the impacts of ex-Tropical Cyclone Alfred, many residents are facing the challenging task of cleaning up their homes and communities. While safety remains our top priority, we also urge everyone to be vigilant for fire ants, which may have been disturbed by the recent weather.
These invasive pests pose serious risks to your health, and the health of your animals and pets, with their aggressive behaviour and painful, fiery stings. We’re also aware the heavy rain and flooding have encouraged fire ants to move, or in some instances, raft.
Tips for looking for and reporting fire ants during clean-up
1. Look out for fire ant mounds
After heavy rain, fire ants build their nests higher, making them more visible. As you clear debris, check for nests in disturbed areas, such as:
- near footpaths, driveways, and garden beds
- under timber, rocks, and pavers
- near utility pits or electrical infrastructure.
Fire ant nests can appear as mounds or flat patches of loose soil with no clear entry or exit holes.
2. Spot the ants
Fire ants are small but aggressive and will swarm when disturbed. Look for ants that are:
- copper brown in colour with a darker abdomen
- measure 2–6 mm in size
- vary in size within one nest.
Please take caution if you see a nest or ants that match this description—fire ants can sting, and their venom may cause severe allergic reactions.
3. Report any sightings
Report your sightings online or by calling 132 ANT (13 22 68) within 24 hours.
4. Be cautious when moving debris
We know many Queenslanders have a big clean-up ahead, and moving debris is unavoidable. Be mindful that fire ants may be hiding in soil, potted plants, branches, or other materials, or in floodwaters. Where possible, check items before relocating them and take steps to help prevent fire ants from spreading.
Queenslanders have always come together to recover from disasters, and this time is no different. By staying vigilant, reporting fire ants promptly, and being mindful when moving materials, we can protect our homes, communities, and environment.
Stay safe, stay alert, and let’s keep Queensland fire-ant free.
