Hi All, Let me shed a little light on Boric Acid / Roach Killer. Years
ago, I had a vending company, and one of my locations was the Food
and Drug Administration. This is the place that checks food for
poisons, as small as 1 part in a Million. Obviously, they didn't
want me to use Insecticides to control the roach population around
the coffee machines.....sooooo....I had to do some studying as to
other natural means of bug control. The first suggested solution,
which I eventually used , was diatomaceous earth. This is what is in
swimming pool filters, and is actually the skeletons of plankton from
the bottom of the ocean. It is small singular crystals of silicon.
As we have skin to keep our body fluids from drying out, bugs have a
thin (1-2 micron) coating which protects their body fluids. As the
diatomaceous earth is spread around, and as the bugs walk over it,
it scratches their 'skin' and they die from dehydration. Ever see an
elephant throw sand over their back, or a horse roll in the dirt, or
a chicken scratch dirt and throw it under their wings? All are using
natures way of insect control.
Boric Acid works the same way....so does baking soda... Heres a good
link to explain it..
Love and God Bless
