Big-Headed Ants

Danger

The big-headed ant does not sting or cause structural damage. They do not bite unless their nest is disturbed, and even then, the bite is not painful.

Did you know?

Big-headed ants prefer high protein foods including other insects, seeds and honeydew. If inside your home, they can also feed on meat, grease, liver, fruit juices and peanut butter.

The big-headed ant colonies include two distinct sizes of soldier ants. Measuring at about 1/8 inches, the major ants have disproportionately large heads compared to their bodies. The front half of the major's head is sculptured, while the back half is smooth and shiny. Their giant heads power their biting parts, the mandibles, which they use to attack other ants. Minor workers are about 1/16 in size and reddish brown in color.

Big-headed ants nest in the soil around structures, under objects on the ground, in rotting wood, in tree stumps and in piles of debris on the ground. Big-headed ants commonly nest outdoors but as conditions change, chronic infestations may be encountered indoors.

Similar to other ant species, the big-headed ant undergoes metamorphosis as part of its life cycle. The incubation time of the eggs ranges from 13 to 32 days. Once the eggs hatches, they become larva and the larval stage ranges from 23 to 29 days. Their next stage is the pupal stage which lasts anywhere from 10 to 20+ days. The queens have been known to lay up to 292 eggs per month.
