Type I Formicaria are carved using Ytong blocks for the nest area. These are professionally hand-carved and fashioned into formicaria through a multi-step process we have developed over our years of making "ant homes" (also known as antfarms).
The Fortress is a new formicarium combination from Tar Heel Ants. This design for your ant colonies features a foraging area magnetically attached to the back of a 4x4x2 inch nest.
