Is boric acid the same as diatomaceous earth?
In this regard, is diatomaceous earth better than boric acid?
The main difference of what we have found between two is it's working functionality. That is, boric acid used both indoors and outdoors whereas diatomaceous earth only provides the best output in indoors uses due to its wetness sensitivity. On the other hand, boric acid kills more roaches than DE.
Accordingly, can you mix diatomaceous earth with borax?
This combination is what makes diatomaceous earth so great at killing roaches (and other bugs). To find out where they travel through the most, use one of the cockroach traps from my other post. Borax & Boric acid. Borax and boric acid are commonly mistaken to be the same thing, but they are not.
Diatomaceous earth is non-toxic to pets and humans, but it kills insects by destroying their exoskeletons. The roaches will take the “bait” back to their nest and feed it to the other roaches, who will also die.
