Red imported fire ants thrive in warm, humid environments and are commonly found in pastures, lawns, agricultural fields, and urban areas. They build large mound nests in open areas and prefer moist soil.
These ants are reddish-brown with a darker abdomen. They have six legs, two antennae, and mandibles for chewing. Their stinger, located at the end of the abdomen, injects venom that causes painful reactions in humans and animals.
The life cycle of the Red Imported Fire Ant consists of four stages:
Eggs: Tiny, white eggs laid by the queen.
Larvae: Legless, grub-like young that depend on workers for food.
Pupae: Develop into adults inside the nest.
Adult: Can be classified as workers, males, or queens.
Queens: Lay thousands of eggs in their lifetime and can live for several years.
Workers: Sterile females that live for a few months.
Males: Exist solely for reproduction and die shortly after mating.
Males: Slightly larger, winged, and die after mating.
Females: Winged before mating; queens lose their wings and start colonies.
Red imported fire ants are omnivorous. They consume plant materials, seeds, dead animals, and insects. They are also known to attack crops and livestock.
Fire ants cause significant damage to plants by feeding on young shoots, seeds, and roots. They also protect sap-sucking pests like aphids, leading to increased plant diseases.
Chemical Control: Effective insecticides include bifenthrin, hydramethylnon, and spinosad.
Biological Control: Natural enemies like phorid flies are used in some regions.
Cultural Control: Regular monitoring and removal of nests.
Baiting: Slow-acting insecticides that eliminate colonies.
Direct Treatment: Liquid and granular insecticides applied to nests.
Prevention: Sealing entry points to buildings and monitoring agricultural lands.

Numerous resources, including YouTube videos, depict their behavior, nest-building habits, and aggressive nature.
They can survive floods by forming rafts.
They have a painful sting that causes allergic reactions.
Their colonies can contain multiple queens.
They attack in large numbers, making them dangerous to humans and animals.
