Ants like cookies

I've had a battle with ants the last month or so.  The sure do love cookies!  My roommate left some cookies on the kitchen counter and the ants were all over those cookies.  Bread?  Break sticks?  Not so much.  So my roomie bought more cookies and this time put them on the other side of the kitchen on top of the microwave which is on top of the fridge.  The ants sniffed those suckers out pretty quick despite the attempt of my roomie to hide them.
