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.
How to use Hydrogen Peroxide to Control Cockroaches
We recommend using 3% hydrogen peroxide, found in drugstores, mixed with an equal amount of water to create a garden-safe insecticidal spray. If that doesn’t work on the bugs, you can increase the percentage.
Things You Will Need
- 3 percent hydrogen peroxide solution
- Dishwashing liquid
- Spray bottle
- Measuring cup
- Rubber gloves

Can You Spray Plants with Hydrogen Peroxide?
Hydrogen peroxide is safe for plants because it encourages additonal oxygen molecule. That provides greens with extra dose of oxygen. To administer, simply mix 3% solution, add 1 teaspoon (5 mL.) per cup (240 mL.) of water in a spray bottle and mist the plant.
