Fire Ants

Fire ants are omnivorous. Known to eat meats, greasy and sweet materials. Fire ants are omnivores, meaning they will feed on animal or vegetable sources of food. The fire ant worker’s diet includes insects, earthworms, ticks, spiders, arthropod eggs, honeydew and other sweets. Plant sources of food include seeds. Young and newborn vertebrate animals eaten by fire ants include birds, rodents and calves. Generally, fire ants readily consume carrion (dead animals) regardless of whether the fire ants themselves caused the animal to die. Fire ant larvae are fed by the worker adults and eat only a liquid diet until their third larval instar is complete. Fourth instar larvae are capable of digesting solid foods.

Total time from egg to adult averages 30 days; workers may live up to 180 days; queens live two to six years. One common sign of fire ant activity is the worker and swarmer ants. Other signs can be their sandy earthen mounds, which are usually more visible after recent rainfall, or the complaints of customers who are being stung by ants. Fire ants favour warm, sunny conditions. They prefer dry fields and avoid shady areas such as woods. Typical mounds can grow up to 61 cm in diameter and 18 cm high. These colonies can contain several hundred thousand ants, including at least one queen. When attacking, fire ants first use their mandibles to grip their prey, and then inject venom through a stinger.
