Never tried that, but I can tell you boric acid is this white powder that works ridiculously well at exterminating cockroaches. You sprinkle it on the floor around the edges and it both poisons them when they eat it as well as tears apart their exoskeletons when they touch it like little shards of glass. It's just nonfatal enough on first contact to let them go back to where other roaches are before they die and then get eaten by their roach friends who also get poisoned or torn apart in the process. Also as harmless as table salt to a human.
