In an ant farm gel specially developed for ants you can clearly see how worker ants (without queen and brood) make a tunnel system together, suitable for all ages. Do you want to see how a colony with queen, workers and brood develops? This can be done in an ant farm plaster, sand or acrylic. You need a little more patience (advice age from 8 years).
Both the harvester ants (Messor barbarus) and the black road ants (Lasius niger) are good species to start the hobby of ants as pets. The harvester ants are our favorite ant species because they also collect seeds and use them as food, super fun to observe!
