For the last seven months, my household has depended solely on using diatomaceous earth for flea control as well as ant control AND as an anti-parasitic. I dust my kitten every other week with this powder and have only seen a flea once so far, and even then a few dustings every other day cleared that flea and any others on him right up. I also put it along the cracks in my house to keep unwanted bugs such as fleas, ants, spiders and cockroaches out.

In an event when he had a parasite from the shelter he came from, I supplemented his diet with diatomaceous earth to flush them out and it worked spectacularly.
In particular I trust True Raw Choice more than competing brands like Pet Star because I know exactly where its manufactured and made of all human food grade ingredients.
