HELP THERE IS LITERALLY ANTS IN MY ROOM

OK SO I HAVE TO GET MY ROOM CLEAN BC MY ROOM HAS ANTS IN IT, just laying in my bed until I decided to draw something or put something on my wall. I decided to get my pens and pencils and stuff until I saw ants on my floor. I don’t necessarily have food in my room except the ice cream that I was eating earlier, but I just noticed a bunch of ants they were very tiny and I have told my brother it is like 12:08 and I have to clean my entire room to kill these ants and get them away
