This acrylic nest is suitable for a colony of early workers up to approximately 50 workers (depending on the species).
Water can be added with a pipette into the water reservoir; be careful not to overfill, or it will overflow.
It's important to do this about twice a week to ensure the colony has sufficient moisture.
