boric acid is made from borax so they are related...
the thing is... all insects wear their skeletons on the outside.
called the exo-skeleten ...and once you perforate it with
something they dehydrate.
if you look at this enlarged photo you'll see tiny fibers on the legs of
ants.... thats where borac acid powder clings to the ants leg and it
burns a hole in the leg and they die.
