Perfect conversation pieces that come with a vented hatch on top to keep in those pesky escape artists. A ledge in the outworld allows the upside-down application of fluon and other anti-escape barriers, which are a must for containing Crematogaster, Tapinoma, and other species of ants.

These outworlds are 8"x4"x4" or 20cmx10cmx10cm  and are compatible with most formicaria we stock
