Western Harvester Ant colonies are commonly found in bare patches of ground and should be walked around, not through.

Auburn red Western Harvester Ants are large ants compared to common urban species. They can form colonies of up to 3,000 workers that are often active and visible around the opening of the underground nest. Females have wings and swarm during the summer season. They eat plant seeds and other insects.

Plants around or near the colony are removed (by them) to allow full sun, which can subsequently remove habitat from other encroaching insects. Nests are covered with gravel or loose soil. Activity tends to slow down during the hottest hours of the day (noon to 4pm). They are aggressive defenders of their home, so anything or anyone disturbing or damaging the entrances will be subjected to biting and stinging. Their jaws are large and strong, so bites are painful and will leave a mark. Removal of colonies can be done by professional exterminators.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Western Harvester Ant may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Western Harvester Ant. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
