Some people use b.a. as a barrier against roaches...would
be nice around a building, if it worked, but it is also water soluble so
disappears in the rain.

The reason Boric Acid works on roaches is that, in spite of the
perception, they are pretty clean insects. They end up licking their
feet like a cat and ingest the poison.


That's why diatomaceous earth kills them. When they run their legs
over their shell, the diatomaceous earth scrapes the wax off which
hold moisture in their bodies, the roach will soon dehydrate and die.
