Product Description

The Western Harvester Ant (Pogonomyrmex occidentalis) is a medium-sized ant that is a great beginner species. Feeding is easy because they eat mostly seeds. They do sting but escapes are unlikely due to their lack of climbing abilities.


Maintaining a suitable temperature is crucial for development. Ideally, their nest should be kept between 85-92 degrees Fahrenheit, with a heating gradient if possible. Heating gradients can be obtained with a heating cable.


Their diet consists of liquid sugars like byFormica Sunburst, small seeds (bluegrass or dandelion are preferred), and an optional weekly protein source like crickets, fruit flies, and mealworms.

Colony Size

Queen, 25+ workers, eggs, larvae, pupae.


We generally sell our ants in test tubes. If local pickup is an option for you and the colony is large enough to move into a formicarium, we may be able to move the colony for you provided that you buy the setup from our store.


Since their diet consists mostly of seeds, a pile of seed husks will develop quickly. We highly recommend buying The Ant Vacuum from our store to aid in cleaning up the husks from the outworld. If the ants accidently get sucked into the vial, you can remove with your fingers provided that you are wearing surgical gloves.
