Quick Overview

The European Harvester Ant Messor barbarus.
Please note that we only ship ants within Europe.


The European Harvester Ant Messor barbarus.

Messor species are from warmer regions of Europe such as Spain and Portugal. It is recommended that you keep your queen in the test tube she is supplied in, and store her in airing cupboard until her first workers hatch (remember to hibernate your queen if she hasn't yet laid any eggs by the time winter arrives).


Messor ants primarily collect seeds from plants as their main food source hence the name harvester ant. A selection of seed should be provided, they particularly like grass seeds. Although Harvester ants prefer a dry climate it is recomended that the sand/soil is kept damp around the main nest chambers, care should be taken not to over dampen the seed storage area of the nest as it may cause germination or mould growth.
