0 stars, no effect, it’s rat protein, it or they ate a whole bag and got bigger and stronger. It did kill them 10 years ago but now it’s made to help them. So what ever y’all stop putting in there to cut your cost to make it kill them put it back. I hope people read reviews, so they know it doesn’t work.

It’s great gets the job done

I've been using this for two years now. In an attempt to stop mice before they find a way into my house I've placed bait boxes around the outside of my home. Unlike the pet safe bait I use now the rodents love this stuff and it disappeared quickly. The fact that I never saw or smelled any dead mice or rats didn't bother me because I assumed they were dying in their burrows. After switching to pet safe bait outside I still had a bag left and decided to use it on mice that had made their way in my house. Two packets disappeared in four days. I put more out, same result. I was prepared to go looking for dead mice but never smelled any. Google the main ingredient - diphacinone - and you'll discover this is a first generation poison that's been used since the 1950s and most rodents are now immune to it. You're paying good money for rodent snacks. There should be a warning label stating this. Don't waste your money.

I have to say this is the best I have found. I have never had to deal with Rats before. With all the rain and woods around us being cut we got some. Not easy to get rid. I tryed 4 store n 2 homemade poisons. Then a friend told me about this. N she was right. It’s the best
