This acrylic nest with an outdoor area is suitable for a colony of 20 to approximately 300 workers (depending on the species).
Water can be administered with a syringe in the sponge; be careful not to overfill, or it will overflow. It's important to do this two to three times a week to ensure the colony has sufficient moisture.
