I can’t believe all these stories. I am so sorry to all of you. I beg you all to check into Diatomaceous Earth or better known as DE. Make sure this is the Food Grade DE, the pool grade can kill your pet. I only use Food Grade DE on my pets for flea and tick control. It is mechanical not a chemical kill. You can feed it to your animals daily and dust them with it. It can also be applied to carpets and pet beds. The only thing you have to be careful about is getting the very fine dust coating their nose. So cover their nose or make sure you use down wind of their face in windy conditions. It is totally safe other than that. I have used this and organic control in the yard and have never had a bad problem with fleas or ticks.
