Was it ... 2007 ?? when I first heard paul stamets speak? It was at bastyr. An amazing experience. And although I walked away certain that paul stamets was saving the world in four different ways, something that I thought was the most important was the thing about the ants.
It goes like this: suppose your house, being made of wood, is being consumed by carpenter ants. My feeble knowledge in the space says: if you see one, there are a hundred you don't see. So it would seem that diatomaceous earth (DE) isn't gonna work. For DE to work, there has to be a lot of it and the ants have to get a lot of it on them. But if they are comfy in the wood, then you aren't gonna do much.
So, up until 2007, I could only think of IPM: come up with stuff that brings the smallest possible toxicity to the situation. I am really uncomfortable with IPM. It is a gross violation of my standards. There is a lost of non-toxic things you can do (DE on the floors, DE in the walls, DE everywhere, move the wood piles away from your home, try to learn where, exactly, the ants are .... etc. etc. etc ...) but in the end I suspect that there will still be some homes that I cannot come up with a way to save in a non-toxic way.
We struggled with this very issue in this thread:
https://permies.com/permaculture-forums/308_0/critter-care/carpenter-ants That changed in 2007.
Paul stamets has a rich story of finding a fungus that if you put it out on a little plate, the carpenter ants find it, take it to the queen and the rest of the colony and .... problem solved.
There is even a picture of an ant with fungus growing out of it. (maybe somebody from FP can link to such a pic?)
So! The really big question now is: when is
fungi perfecti gonna come out with this product?
