Good but be very careful.

I have used this product before not from this seller or even from Amazon. It almost killed my dog. I did not follow directions as well as I should have and she was able to eat some of the powder. I had to rush her to the vet for emergency care. If I had not gotten her to the vet in a timely manner she would have bleed to death from internal bleeding. Be VERY careful and follow all directions exactly. This does kill the fleas and any other bugs that hop or crawl in your house. Amazing results.
