ok i recently bought a ytong block and hollowed out bits of it for my red ants using a mini drill like a dremal. now once i put the anys into the formicarium with the ytong buried in the sand/loam. however the ants dont seem to want to go into it and if they do they seem to get covered in the white dust from the block and start either dying or acting wierdly
anyone got any ideas if the ytong can be toxic or anything?
