Here's something I noticed the other day. I was sitting at the patio table blowing my cloud at the table trying to make it look like a cool foggy table when I noticed the ants would stop and wipe their antennas. I've blown my cloud directly at ants several times since and they always wipe their antennas. It's like something in the vapor cloud messes with their antennas for some reason. Anyway, something to do when your bored.
