Ants in the house are generally not a good thing. You need to learn how to get rid of ants in your house, which is why you landed here. It is highly unlikely that you will be able to drive the ants out of your house, so you will probably have to kill them. There are several ant killer and ant bait products that work wonderfully.
A few of the good ones, like this Terro brand Liquid Ant Bait Station (6-pack), can even be purchased online via Amazon. The same products, and many others, can be found in your local hardware, grocery or general store. Simply follow the directions on the package to learn how to effectively get rid of ants in the house.
You could also experiment with making your own homemade ant killer or ant traps, which is what this site is all about. This can be just as effective as the store bought stuff and might save you a little bit of money.
