Colony of Ants

Clearly Summer is here.  We had a major infestation of ants this weekend.  A few ants here or there don't bother me, but an entire colony is a MAJOR problem.  I had no idea one crust of PB&J could start such craziness.  How do they even know its there?

After spending much of Saturday cleaning, laundering and recleaning our kitchen I think I am currently the controlling power.  After it was all cleared up, I was able to research environmentally friend ant repellants.  We have always used cinnamon as our first line of defense, but will try some of these alternatives in the future http://www.peta.org/living/humane-home/tips-humane-nontoxic-ant-control/
