Our All Stop DE-Stroy Pest Control Eco Dust. It is food grade diatomaceous earth. Diatomaceous earth is crushed up fossils of fresh eater organisms and marine life. When the head lice crawls through this dust, it acts as shards of glass cutting their exoskeleton causing the head lice bugs to dehydrate and die.
You can use this powder in your environment to kill any head lice bugs that may have fallen from the head.
