I need a bit of help.

We haven't had a bug infestation at this house in a long time, even though we haven't had a professional exterminator come and spray in quite awhile. We have good habits about keeping food in one area, out of the way, and disposing of it ASAP. No food is in the bedrooms and my ferret and dog eat their food in one place and it's fairly contained in that place (and outside of my bedroom). The exception is the odd treat or two that I give to my ferret, Maddox, that he hides underneath furniture in my bedroom, though I've put a stop to that only allowing him treats if he eats them right in front of me.

However, we have an ant infestation and it's only in my room. We can't find a hole or crack along the floor that is letting them in, and there's no obvious crack or hole around the windows (though they're probably coming in from the windows rather than the floor). I'm not afraid of ants, but it's driving me crazy when I try to study on my bed and have to kill an ant every three seconds. One of the ants bit me on the shoulder earlier this morning as I was laying down. I continually have the "bugs crawling all over you" feeling.

I'm afraid of getting a professional exterminator to spray because of potentially hurting Maddox and Bug (my dog), but especially Maddox.

Does anyone have any home brew ways of getting rid of ants that won't hurt my ferret or my dog? My sister suggested dish soap on the ant path (we'd be putting it along the floor and around the window and it shouldn't hurt Maddox when it's dry). Any other suggestions?
