The red imported fire ant has evolved to survive flood conditions by forming a living raft. When their nest floods, up to 500,000 worker ants surround their queen and her eggs, linking arms and forming a floating raft with their waxy bodies. They create pockets of air for buoyancy and link themselve

FAQ

1. What are floating fire ant rafts?

Floating fire ant rafts are clusters of fire ants that join together by gripping each other’s legs to form a floating structure. When their nests are flooded by water, the ants will instinctively cling to each other and form these rafts as a survival mechanism.

2. Why are they dangerous?

Floating fire ant rafts are dangerous because they contain thousands of fire ants that can sting humans and animals. Their stings can cause pain, swelling, and even allergic reactions. Additionally, these rafts can easily drift into homes or other structures, causing infestations.

3. How long can they survive on water?

Floating fire ant rafts can survive on water for several weeks as long as they have access to air pockets. The ants are able to rotate positions on the raft to ensure that everyone gets a chance to breathe.

4. Can they cause damage to boats or other structures?

Yes, floating fire ant rafts can cause damage to boats or other structures if they are not removed promptly. The ants can chew through wood, rubber, and other materials in search of food or a dry place to build a new nest.

5. Are they found only in the United States?

No, floating fire ant rafts have been observed in other parts of the world, including South America and Asia. However, the species of fire ant that forms these rafts, Solenopsis invicta, is native to South America and was accidentally introduced to the United States in the 1930s.

6. Can they survive in saltwater?

Floating fire ant rafts can survive in saltwater for short periods of time, but they prefer to stay in freshwater. The ants are able to tolerate a wide range of salinity levels, but prolonged exposure to saltwater can be harmful to their health.

7. Are they a threat to wildlife?

Yes, floating fire ant rafts can be a threat to wildlife, especially small animals that may be unable to escape their stings. Invasive fire ants like Solenopsis invicta have been known to outcompete native ant species and disrupt local ecosystems.

8. What should you do if you encounter a floating fire ant raft?

If you encounter a floating fire ant raft, it is important to avoid contact with it. Do not attempt to remove the raft yourself, as this can cause the ants to disperse and potentially sting you. Instead, contact a pest control professional who can safely remove the raft and prevent future infestations.
