ANT INVASION!!! THEY KEEP COMING BACK HELP!!!?

we have tried everything! our kitchen, bedrooms, living room, everywhere! I have no idea what they are after other than to piss me off! We have tried bait stations, nothing. Home Defense spray, nothing. We have vaccumed them, swept and mopped them, even windex'd them and they keep coming back! We have all the sugars and sweet things in air tight containers, nothing works. We are in an all out WAR with the ants and are LOSING! Any help would be awesome! thank you!
