There are no poisons involved, instead, diatomaceous earth kills fleas by puncturing their exoskeleton and absorbing vital fluids from the flea. You use DE by simply sprinkling it over furniture, bedding, or linens where fleas are present and, after a few days, vacuum/wash those same areas.

Numerous studies and practical applications have shown that diatomaceous earth can be highly effective in controlling flea populations. It works by dehydrating fleas, eventually leading to their demise.

When battling a flea infestation, diatomaceous earth is a natural alternative to chemical pesticides. Unlike crystalline silica, a known health hazard when inhaled, food-grade DE contains less than 1% crystalline silica. This low percentage makes it safe for use in flea control.

It is a fine powder that comprises of microscopic remains of fossilized algae called diatoms. It is effective because it cuts at the waxy layer that protects fleas. This substance can also block up and damages the fleas’ respiratory system. In the real sense, diatomaceous earth causes the fleas to die because of lack of air and dehydration.

The goal of using diatomaceous earth for flea control is to minimize fleas in your pet's environment. The powder should not be applied directly to pets unless you are specifically instructed to do so by your veterinarian. Although it is not toxic, it can cause dryness and irritation to the skin, eyes, and lungs.
