Fire ant nests in Brisbane rarely look like the tall mounds people expect. They are usually low and flat, often just a patch of loose, disturbed soil in a sunny lawn, a garden bed or beside a footpath, with no obvious entry hole on top. Some show no mound at all. If ants pour out and swarm when the soil is disturbed, treat it as suspected fire ants and keep children and pets away. Under the Biosecurity Act 2014 you must report suspected fire ants within 24 hours. The National Fire Ant Eradication Program takes those reports and runs its own treatment and surveillance. Fire Ant Solutions is a private, licensed business, not part of that program. People call us when they want nests treated on their own timeline, when there are several nests or a high risk site, or when they need a written record for a sale, a build or a soil movement. There are two main ways we treat a Brisbane property. Direct nest injection puts a registered insecticide straight into the mound and its underground chambers. It kills the queen and the colony at the source, and activity usually drops within days. It suits single mounds, backyards, playgrounds and anywhere a sting is not acceptable. Baiting suits larger properties and multiple nests. Worker ants carry the bait back to the colony, and the colony collapses over several weeks. Many jobs use both. Every Brisbane job follows the same steps. We inspect the property and confirm whether the ants are fire ants, treat every active nest we find, check the result, and give you a record of what was found and done. For builders, developers, schools and councils we can map nests across the whole site, so you have a clear record for auditors or insurers. Don't wait for a nest to spread. One untreated mound can become several within weeks, so the sooner it is treated, the smaller the job.
