How to get rid of ants?!?! FAST!! HELP!?

We have ants all over our counters and in our sink in the the kitchen. It is disgusting! I cannot stand it, it makes me want to move. Please help. I want them gone fast and I don't want them to ever come back. s: I hate ants. I am pretty sure they are sugar ants. Ugh, I feel like they are crawling all over me. I hate this. Please help. And don't worry about killing them humanely, I want them DEAD NO MATTER WHAT!
