Yesterday morning I went to cook breakfast and the stove top and hood were carpeted with ants. I did my usual anti-ant routine swabbing them up with a sponge and dunking them in soapy water. I put on disposable gloves when they started nipping. Then I broke out the ant traps, little flat containers of liquid where you snap off the tops and the ants come to the bait and get zapped. A few months ago I went through basically the same routine, but in the foyer with what I think were slightly larger ants, though both sets were small in the ant kingdom. Okay, now here's the mystery. In both cases, as the ants dwindle in number, there are a few hanger-ons, eventually just a few here and there, and then you get up after about two days of this, and not only are many gone, but they are all gone -- no casualties, no remains, no nothing. Do ants retrieved their dead before perishing? How does this happen? Direct ascent to ant heaven?
