Weaver Ant Care

General care instructions for Polyrhachis dives

A fascinating species of weaver ant. This species come from Asia and are now found in parts of Australia. They are mostly ground dwelling, weaving large masses of grasses and sticks to form their complex nest systems. An easy species for the beginner, however they are very good at escaping and climbing.


Daytime & Nest Temp 28-30 C, Night 24-28 C. 50-70% humidity


Well lit enclosures.

Avoid direct sunlight


Weaver ants are good climbers and good at escaping. Ensure that your habitat is secure. As they have a requirement to weave, it is advisable to always make sure they have grasses, sticks and wood shavings available to collect for their nest. A sandy loam soils works best to maintain humidity and a nice surface for the ants. We do not recommend using the commercial purchased ant gels at all. Weaver ants use the silk produced by their larvae to weave. Weaver ants will need a medium to large space to forage, form a nest and weave... this can be made up from lots of smaller enclosures connected with tubes or open air with a water moat. We would recommend using any of the ant farm modules, Ytong, Glass tanks or acrylic tanks (although acrylic can warp with heating)


Most ant species enjoy the sugars from honey or sugar water. They also have a requirement for protein in the form of dead insects. We would recommend freshly dead locusts, crickets or fruit flies.


This species can have multiple queens per colony. They are classed as a 'Polygyne' species. The queen is around 12mm in size. Workers are around 6-8mm and colonies can form up to 2000 ants. This species do not have soldiers


This species does not need to hibernate.

This species can shoot formic acid when defensive so handle with care

Ants will arrive in test tubes with water on one end and a cotton wool bung on the other. This enclosure is suitable for them to remain in until there are sufficient workers. Ants should be fed within the tub or introduced to a small out-world. Once the tube starts to look busy, this can be connected to an out world and additional nest tubes. Always allow ants to move themselves to new enclosures, do not tip them into a new habitat.
