Bug problem PLEASE help?

Question:um well five seconds ago, an ant fell from my ceiling and right next to me. I flipped out. It got away :(

then i was walking out of my room, and i saw another one crawling on a piece of furniture. Thenas i attempted to catch it, there was a dead one like a few inches away on my carpet.

I live in a pretty nice home.i have a big room..(i can fit a queen sized bed i my room, and still have room for my desk, computer, a drum set, and other furniture)

anyways i've noticed that there HAVE been a lot of ants in my room since last week..where are they coming from and how can i get rid of them.

I think this happened to me last year too. Or RIGHT when spring started i can't remember. I think they were coming from my window so i sprayed it and never saw them again. Now i'm not sure.

Answers:
If they are big black ants they may be carpenter ants and can damage your home as much as termites. You need to get an exterminator for this problem. If they are smaller ants, there will be a trail where they come in the house, usually near water. Make sure you have no food, especially sweets, in your room. Get ant bait at a home supply store. If you live with your parents, tell them about the ants.
