This product is terrible and extremely harmful to pets. I have 7 cats and each one experienced problems after I sprayed this product in my house to try to kill the flies. I contacted Zevo who transferred me to Safety International and I spoke with a Dr. Benson, a vet who informed me that it can cause respiratory conditions in cats. In fact, one of my cats who wasn't sick suddenly passed away several weeks after I used this product in my home. The vet from P&G contacted my vet who informed them this cat was not sick before this.
Length of Use: 2+ years
Bottom Line: No, I would not recommend this to a friend
