Bring home the beauty and wonder of the Messor aciculatus and experience the joy of observing these incredible creatures in action.


Colony Form

Please note that these ants are polygenous so multiple queens might live together happily under one roof. The workers are not polymorphic like the other harvester ants and are similar in size from 4mm to 5mm.




Messor ants prefer to nest in sandy-loam soil and shrub areas.


Colony Size

Their colonies can grow to about 10,000 workers and are a great choice for those looking to start their ant-keeping journey.



Messor aciculatus queen ants' lifespan is up to 25 years and is 10-11mm. The queen is claustral so no food is needed during the founding stage. The workers will live up to 2 years and aid in the growth and success of your colony.



Their main food source is seeds, making them easy to feed and maintain. Our Messor aciculatus ant colonies are healthy and mites-free, so you can feel confident in your purchase.


Messor aciculatus feeding

Feed them into the outworld only! Harvester ant's main food is seed mix.

How to feed them and how much?

So the golden rule is 1 seed per ant per month. Feed them every two weeks (half dosage, for instance: 30 ants = 15 seeds every two weeks).

The first feeding dose must be doubled. Keep an eye on their food storage so they have one nest’s chamber full of seeds all the time.


Suitable Ant Farm Kit

Once your colony is large enough (10-20 workers) you can consider moving it into an ant farm. We would recommend the small-medium ant farm for a small colony of Messor ant species. The best options among our products are the A7 Plus, Antie or the A6 Ant Farm where you can enjoy watching them harvesting in the outworld.

Harvester ants need a higher temperature for their proper brood development so 25-27°C would be great. Temperature above 28°C will endanger the queen ant!


Ants' Escape Prevention

Harvester ants are not the best climbers but Messor aciculatus are so if you do not want to deal with escaped ants, which is a common issue while you feed them, apply about an inch wide of our PTFE Fluon.



To remain healthy, your queen and worker ants require proper hibernation during the winter months, but it's not a must during your ant colony's first year. The Messor aciculatus ants hibernate through the winter starting at the end of November and wake up around late February/early March. To hibernate, the temperature of the nest needs to be reduced to around 15 degrees Celsius, which is not too cold for the ants to survive.
