No, termites always create living conditions for themselves that are very specific in regard to temperature and humidity. In some parts of the country and some species, this translates into mounds, in others it translates to a subterranean existence. In my part of the world, they find their ideal conditions at roughly 300' underground -- far too deep to kill by any means other than chemical barricades that prevent their access to the surface. Anteaters could certainly help contain certain types of termites in certain areas, but their overall effectiveness would be negligible in most circumstances.
