The ants are back! We have kept them at bay inside the house, but outside, that is a different matter. A single dropped crumb on the patio and the next morning a stream of ants appear, hundreds of them in a neatly organized operation to dismantle the discarded food and store it in bits and bites for later use.
How do they do this? Do the wandering scout-ants have cell phones? When they make a discovery do they place a call back to home base and say, “Send the troops. We have food!” Who organizes the operation? Who tells these worker ants to answer the call, and who plots the shortest and least obstructed route to the treasure?
