(!!! Was half the garden already undermined) had a real Wühlmausproblem in our area. I therefore decided to try it with this vole. The case properly rubbed with earth and also the bait (a piece of carrot). It is important to look first if the "transition" is still used. Simply make a finger-thick hole in the course, if the vole is still used to the resealed within 2-3 hours. Did then dug the aisle with the shovel, paving the transition nice and the trap close to it provide very important everything is around the funnel well with earth so that no light seal. What can I say, after about 2 hours before the first time the top bracket and a mouse was inside. This was repeated the next 3 days 4 times, did so in just 4 days 5 voles so caught, will decry anything, but there are about 2 weeks since any new courses, holes etc .. more. Can this trap all Wühlmausgeplagten recommend only heat least !!!
