ANTS and Air Conditioners??!!! Who knew?

My air conditioner has been broken since Friday. The repairman just arrived (Monday) and to my surprise-the problem is Ants!!! Seems some ants got in the way of the "contact" on the unit outside. As the ant got japped, the "aroma" lured more ants to the same area, and after a while, there was an ant buildup, which prevented the necessary contact. The area was cleared and he recommends ant killer in the unit(s), as well as around the unit(s) each Spring.

As my father would say...."I hain't never!". Gotta be Southern to understand this one, y'all....
