Feed them!!
I know it sounds absurd, but trust me on this one! (I actually discovered this inadvertently...)
I still have to make some more experimenting, but here's how it goes:
If you're having trouble with ants, you know there's the trouble of having scouts all around your house and the trouble of having them eating your things, right?
So now, suppose you get something for them to eat and place it somewhere it doesn't bother you... they will find it and attack it! You'll see the scouts (most of them, anyway) will join the main crowd, and leave your home in peace for a while...
One or two last things:
1) Consider well where you place the "bait"... it should be someplace where the path they'll take won't bother you, but the longer it is, the longer they'll take :-)
2) Remember this is probably cheaper then buying chemicals, and it doesn't smell :-)
