I know they say that the regular bug sprays - against ants, wasps, roaches( reading a label her) don't work against bedbugs. However I suspect that there are products and processes that do work that have not yet been discovered.

For instance, I have never heard of the common cleaner '409' being touted as a wasp or yellow jacket killer, and yet by accident I discovered it works wonderfully well.

You know the effect that the common spray has on yellow jackets? They go into a frenzy that is almost more scary than being attacked by one. Well, a spritz of 409 drops them in their tracks, so to speak. No buzzing, no hysterics.
