Hey John! Thank you so very much for this info. It really is fascinating stuff for sure! I contacted the company Fungi Perfecti, Stamets', and found out that they are currently trying to get a EPA approval. They have patents that are published and waiting on two more. They are saying that it could take $2,000,000 or more for this approval!! Anyway, they cannot sell it until they get that approval, soooooooooooooo, I'm back to trying to figure out a solution for these darn ants. Any other suggestions?
