The ants go marching

I love my new house, however it comes with some pets, ants. No one has yet lived in this home so we are trying to take it back from the ants. We have border sprayed, baited, and poisoned again and they still keep coming back for more. Obviously the kitchen is the worst. I am trying my patience with the poison they take back to their nest. But to me it looks like they are just bellying up to the bar and staying there. Meanwhile all their drinking buddies keep showing up. I know it takes about 2 weeks to do it right but the raid is about to come out.
