What You Need To Know about Red Fire Ants
Red Fire Ants Australia are rapidly becoming one of the most dangerous invasive pests threatening our homes, environment and agricultural industries. These aggressive ants, scientifically known as Solenopsis invicta, cause painful stings, build destructive nests and spread quickly if not controlled effectively.
Understanding what they are, how to identify them and what to do if you find a fire ant nest is essential for protecting your family, pets and property.
What Are Red Fire Ants?
Red imported fire ants (Solenopsis invicta) are small, highly aggressive ants known for their fast-moving behaviour, painful sting and ability to survive in harsh conditions.
Key Characteristics
Reddish-brown colour with a darker abdomen
Workers range from 2–6 mm in size
Build dome-shaped mounds or nests
Swarm aggressively when disturbed
Spread quickly across lawns, paddocks, landscaping materials and even machinery
These ants pose a serious threat to people, wildlife and livestock. Their ability to relocate entire colonies quickly makes them difficult to control without specialised equipment.
Fire Ant Bites: Why They Are Dangerous
A fire ant bite is not just a simple sting. Fire ants attack in groups and inject venom that causes intense burning, itching and swelling.
Common Bite Symptoms
Sharp burning sensation
Itchy, swollen red spots
Small white pustules forming after several hours
Risk of allergic reactions in sensitive individuals
Pets, children, livestock and elderly people are particularly vulnerable to severe reactions.
How To Identify A Fire Ant Nest
A fire ant nest can appear almost anywhere, which makes early identification extremely important.
Look For:
A loose mound of soil with no visible entrance holes
Dome-shaped nests up to 40 cm high
Increased ant activity when the mound is touched
Clusters of ants rapidly swarming out to defend the colony
Fire ant nests are often found in:
Lawns and gardens
Farmland and paddocks
Under concrete slabs
Around fence lines
Near electrical boxes or irrigation systems
Inside mulch, landscaping materials and soil deliveries
If you spot a nest, do not disturb it. Fire ants will swarm aggressively when threatened.

What To Do If You Suspect Red Fire Ants On Your Property
