Total cessation of life for a roach sounds pretty damn good. I hate how the sprays let them live long enough to crawl back under the stove or behind the cabinet so I can’t actually SEE the corpses. How do I know they’re not all taking a little roach shower back there, washing off the Raid, huh? (OK, OK I know it’s far-fetched…)
It does me no good to envision the corpse attracting the interest of a passing ant or two to run and tell his friends about the new food source.
When I was in grad school, there was a gi-normous roach that lived in the women’s restroom in the wing of the department where I worked as a TA, on the sixth floor of the building. None of us wanted to squash it, because all of us knew that it was easier to ignore a roach that ran away from you than it was to have to clean up a squashed bug that size.
One day, a colleague and I decided that the best approach was to catch the roach and drop it out the window. So we did. We watched that sucker fall down six stories, banging against the building wall several times on the way down. It landed on a cement sidewalk, and was large enough that we could see its brown shape even from the sixth floor, as it scurried away from the building!
