How Do Cockroach Powders Work?

Cockroach-killing powders are dusts or fine particles applied in cracks, crevices, and other hiding places where cockroaches travel. As roaches walk through the powder, it clings to their bodies. When they groom themselves or return to their nest, they ingest or spread the powder, leading to their death.

Top Powders for Killing Cockroaches

1. Boric Acid Powder (The Classic Choice)

Why it’s best:

  • Time-tested, highly effective, and affordable.

  • Acts as both a stomach poison and abrasive, damaging the cockroach’s outer shell.

  • Kills slowly, allowing cockroaches to bring the poison back to the nest—spreading the effect.

How to use:

  • Apply a very thin layer in dry areas where cockroaches hide (under sinks, behind fridges, cracks, etc.)

  • Avoid wet areas and keep away from pets and children.

Popular brands:

  • Harris Boric Acid Roach Powder (USA)

  • Stanfresh Boric Acid Powder (India)

2. Diatomaceous Earth (Food Grade) (The Natural Choice)

Why it’s great:

  • 100% natural, non-toxic to humans and pets (if food grade).

  • Works by dehydrating cockroaches / cockroj—no chemicals required.

  • Safe to use around food areas and in homes with pets.
