Behavior, Diet, & Habits
Little fire ant workers are very slow moving unlike most other kinds of ants. In fact, at times they move so slowly that they are not observed until someone becomes the victim of their very painful, burning sting.
Unlike other fire ants, these insects are not likely to defend themselves in a large, stinging swarm. They are less aggressive and will sting only when pressed upon by an unsuspecting person or animal. In general, if someone is being stung, but no ants are seen, little fire ants are often the cause.
What Do They Eat?
In search of food, little fire ants trail along sidewalks and foundations up around buildings. These insects feed on the following:
- Honeydew from aphids and scales.
- Peanut butter or other oily foods.
- Protein from dead and living arthropods.
Where Do They Live?
Several queens and large numbers of workers, pupae, larvae, and eggs make up a little fire ant nest, which can often be found in places such as:
- Beneath forest floor debris
- Palms or palmettos plant sheaths
- Tree crotches
- Under flower pots
Little fire ants are established in southeastern states and the island of Hawaii, plus they have been reported in Los Angeles county, California.
Little fire ants benefit from both asexual and sexual reproduction, and colonies usually have multiple queens. Most new colonies are formed by budding. This process is when a fertile queen and a group of workers will leave the established colony to form a new colony.
