Termites eating out pastures
As some may know, here in Texas we're in the middle of a giant drought. I don't know if it's in several areas, or just where I live, but a kind of termite is completely eating out everything. In our pastures there's nothing but termite tunnels, except for the areas we've been watering for the horses, but they still eventually manage to get to that grass as well. It's quite difficult to keep good grass going, since the termites are after it all.
Does anyone know of what can effectively kill them, but is still safe for the horses? It's in pretty much all the pastures, but worse in my Thoroughbreds paddock, which leads into the arena, so it can't be anything toxic to them.
