So I have tried making a formicarium out of sand but it did nt work because the sand collapsed too easy. I am thinking of making a formicarium out of silicone putty mold from Michaels (art supply store). Will my Camponotus Pennsylvanicus bite through that stuff? I've heard about S. Invicta shredding through silicone but I wonder how this silicone mold putty fairs against Camponotus.
I can't use Hydrostone or any other hard materials for nests because I don't have heavy tools-just a tiny toolbox with screw drivers and hammers etc.
