I have a suggestion. Put the soil in black plastic bags and let the sun cook it for a while. That should fry your termites.I used a app that's suppose to identify bugs by taking a picture, it came back and said subterrian termites. They are about a 1/4 of a long grain of white rice. All white bodies. I had four pots sitting in the yard that had nothing in them, three looked fine from what I could tell but the last one had wet soil in the bottom and these dam things. I was gong to try and recycle all the old soil for a hempy bucket but it looks like now I have to just dump it.
