These ants suck. They don't do anything. They hang out in the wood hole for the skybridge - about the most entertainment I get is blowing them out of the hole from the tube and watching them charge back into the hole and then realize it just blasted them out - get second thoughts - run away - not know what to do except hang out in the hole - run back - remember getting blown out - run away - over and over again. Its mildly amusing. I think I'll seal it up a tiny bit better and let the harvester ants go to work when they get here......
