How often should I feed my Messor barbarus colony?
Feed 1–2 times per week depending on colony size. Always remove uneaten food to prevent mould growth.
How do I prevent Messor barbarus from escaping?
Use PTFE Fluon on the upper walls of the outworld and ensure all tubes and lids are sealed properly.
