Step 1
Obtain food grade diatomaceous earth. This substance, which looks like white flour, is a product of mined fossilized silica shell. It kills all insects without poison and without them ever becoming immune because it dries up the outer waxy surface of the insect, which causes it to dry out and die. But there's also industrial grade diatomaceous earth and you don't need this to kill cockroaches. You must get the food grade type to be safe and natural.

Step 2
Make a barrier to kill cockroaches. Mix one cup of the white powder with a gallon of water and spray around the foundation of your house. Though it's harmless to the bugs while wet, once the water evaporates and leaves the white residue, it will last quite a while as an effective natural method to kill cockroaches. I don't have a specific timeline for reapplying as everyone's weather and situation are different. When we use diatomaceous earth, it seems to keep bugs away without having to respray even after we don't see the residue anymore. But you'll need to discover your own spray timeline.

Step 3
Sprinkle the powder in hiding places to kill cockroaches. Sprinkle small amounts of the diatomaceous earth around in wood piles, underneath pots and stones around the house foundation, cracks, crevices, and other places cockroaches hang out. It's considered safe even for pets and is used as an ingested internal parasite control. Just don't breathe it in (see Warnings, below).
