Does hydrogen peroxide kill roaches? It depends on how strong the solution is. Typically, the stronger, the better. Pouring hydrogen peroxide on a roach will slowly dissolve the flexible hinges between the hard plates of the cockroach exoskeleton, but has no other discernable effect. So, although it will run, it basically rips its body apart.
Diatomaceous Earth does similar thing to roaches. It is basically a powder with sharp edges (if you check under a microscope). The Sharp edges get into Joints (soft areas) of insects with exoskeletons, and it generally cuts them up as they move. It’s safe as far as you don’t breathe in the powder.
