To a true plague of mice to master in a stall, I first tried a grain bait. This has also achieved good results at the beginning, only the portion division was always a bit awkward and you had to be very careful not to mistake something fell to the ground and thus was open to other creatures. After some time, but also lost the effect of the bait was eaten, but the mice stock recovered anyway. Therefore, I switched to this bait. Just put in a bait box and look for commands every few days. The bait is very well received and after a few days can be no more mouse look, carcasses are rarely around somewhere. I've been using these baits now for several months and he enjoys constant popularity in the mice without losing effect. highly recommended!
