Hole Arrangement

Black Oak Savannas were once common across the great lakes, being maintained through controlled burns. Today, only 0.01 percent of this habitat remains. Black oak trees, which thrive in sandy soils, are what dozens of species rely on. 


  • Yellow Sand
  • False Grasses
  • Rainbow Slate
  • Manzanita Branches
  • Oak Leaves
  • Red Base

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. The holes on the outworld are 3/8 inch or 9.5mm.

(If you're not sure about the hole arrangement, it may be best to select Zero, and drill holes later)
