Fire ants are a rapidly growing threat in South East Queensland (SEQ), with eradication zones expanding at an alarming rate. These invasive pests are not only aggressive but also highly destructive to infrastructure, agriculture, and ecosystems. For businesses operating in SEQ, understanding the risks posed by fire ants and taking proactive steps to manage infestations is becoming increasingly critical.

In recent years, fire ants have spread across many parts of SEQ, impacting industries ranging from agriculture to construction. Known for their painful stings and ability to swarm, these insects can pose serious risks to both public health and business operations. As the infestation zones continue to grow, there’s an increasing urgency for businesses to implement effective fire ants control strategies to protect their assets.

In areas where fire ants are established, the spread of infestations can be as fast as 5 km per year under favourable conditions.

The Impact on Infrastructure and Agriculture

Fire ants are notorious for damaging key infrastructure. Electrical equipment, irrigation systems, roads, and even buildings are all vulnerable to fire ant colonies. In agricultural sectors, they can cause significant damage to crops and livestock. Their burrowing can destabilise soil, while their aggressive nature can harm livestock, which can lead to significant financial losses for farmers.

Fire ants have the potential to cause $1.65 billion in damage annually to Australia’s agriculture sector if not eradicated.

In terms of public infrastructure, fire ants are capable of short-circuiting electrical systems and damaging underground cables. This makes them a considerable risk for industries like construction, utilities, and transport. For businesses with critical infrastructure, these infestations can lead to costly repairs and downtime.

Agriculture is especially vulnerable to fire ant invasions, as infestations can lower crop yields and disrupt farming operations. With these stakes, businesses must stay proactive in monitoring and controlling fire ant populations on their properties.

Managing the Risks: Surveillance, Compliance, and Long-Term Solutions

As fire ants continue to spread, the Australian government has implemented stricter biosecurity protocols to curb their growth. Businesses operating in fire ant eradication zones must work with biosecurity services to meet regulatory requirements and prevent further infestations. These services not only help businesses comply with government standards but also offer expert strategies to detect and control pest populations.

Queensland Government guidelines note that non-compliance with fire ant biosecurity regulations can lead to fines up to $400,000.

Beyond compliance, effective fire ant management requires a combination of surveillance, monitoring, and treatment strategies. GIS mapping and large-scale data collection have become essential tools for tracking fire ant populations and anticipating their spread. By integrating these technologies into pest management practices, businesses can better understand the risks and stay ahead of potential outbreaks.

Long-term solutions go beyond eradication. Continuous monitoring and tailored biosecurity solutions can help businesses future-proof their operations against fire ant infestations. By staying compliant with biosecurity regulations and maintaining a proactive approach to surveillance and treatment, businesses can minimise the impact of fire ants and protect their critical assets.
