Beneficial Nematodes, termites, and ants?

Has anyone used beneficial nematodes to kill ants or termites? Specifically Steinernema Feltiae and Heterohabditis Bacteriophora. I was looking for something to kill ants in my vegetable garden that wouldn't poison the soil or us and I like to go environmentally friendly when I can. The gardening website also stated that the nematodes also kill termites and I have them eating my house but don't want to use the commercial guys with their pesticides.
