IT WOULD BE GREATLY APPRECIATED IF, WHEN KILLING ANTS WHILE SHOWERING, YOU WOULD FLUSH THEM DOWN THE DRAIN. ANT CORPSES DO NOT MAKE HAPPY BATHING COMPANIONS.
I had thought about putting in something about "your fellow bathers would appreciate," but that would seem to imply that my family employs a Roman-style bathing arrangement, which we most certainly do not. Come to think of it, our distaste for such an arrangement would be one of the main reasons for why we kill our unwelcome six-legged visitors in the first place. The other reason being that some day (? I hope?) the ants will figure out that all of their friends die when they come in here, and thus decide that coming here is a bad idea. The problem with this, of course, is that they don't all die, since our bathroom is not continuously inhabited with ant-killing humans.
Diatomaceous earth, my friend, diatomaceous earth. We will be spreading it soon over the surmised inbound path of our exoskeleton-possessing visitors, and very shortly thereafter my killing-ants-in-the-bathtub days will be over.
On the bright side, these are not biting ants. It could be way worse.
