Found these while digging a planting hole and again when emptying a wooden barrel planter. Termites?

I know, I was kidding :)

I was unfamiliar with them until a few weeks ago, when we find some coming up through the kitchen floor. Apparently the live like 30' underground and make little mud tubes to the surface to get food. They had to drill like half inch deep holes all the way around my house and pump insecticide into them. Very annoying.
