Hard to tell from the pic could be and ant they call a crazy ant. There is a bait for home use called combat ant bait gel. Home Depot use to carry it. Another one you could try is any of the ant bait stations that have the chemical hidromethlon, abamectron-B1, or my favorite Fipronal. It will be listed under active ingredient on the front of the package.
Baits work slow you have to give them time to work.
You could always just spray (sparingly) with ortho home defense. Remember a little goes a long way.
