If killing bugs gives you a thrill, watch this

  Here's a post which demonstrates how to use Boric Acid to kill insects, in particular, wasps.

  Boric acid will kill all insects, he says. That was my understanding as well. One thing I know for sure, is that boric acid will definitely kill off roaches.

  Put some of this down in the cracks of all shelving, and other places where the roaches hide.

  Just remember one thing about boric acid.  It won't kill immediately.  But it will definitely wipe roaches out, and keep them out.  I used this in an apartment once that was badly infested with roaches.  After treating with boric acid, I didn't see roaches there for the rest of the time I lived there. That was many years.  Boric acid works.
