The double is perfect for Harvester species, it provides places away from the moist cotton to store seeds and reduce seed gemination while in the tube. (although it may not stop it completely it proves helpful). The cork also creates a nice gradient for moisture.
Here we now use these for carpenter ants of all kinds, the colony can move brood, get their wood like feel and have a distinctive entrance to the queens chamber making the trash and rubbish area clear for the ants.
