We have tested these against all other baits out there. Rats and mice preferred these baits over all others. Bait that is attractive is vital to ensure an effective kill. Also very important if you have good rodent food sources close at hand (fruit and nut trees, compost heaps, etc).
These contain Bitrex. A bitter agent that makes them taste very unpleasant for kids and pets.
Will not cause secondary poisoning if your pet eats a dead rat (highly unlikely they will find one, but it's a question we get asked quite often).
