I am suspicious, though I do remember reading about using plain water to kill aphids - apparently they attach to the plant via their probiscus (probiscii???) and are killed when the water blasts them loose, leaving the probiscus behind. The same principle may be at work when blasting critters with soap. Or maybe their spiracles get clogged. Has anyone tried this? <<

Sure.
A little soap or detergent cuts the surface of the tension of the water,
letting it get into parts of the bug that normally stay dry, and that
somehow messes up the wee beasties. It seems faster than drowning, so
I'm not sure what the actual mechanism is. But I don't think it's from
blasting.
