Have the solarbetrienen Mole and mice fright now a good week. When I got the 2 bars, I had to try it the same. As I wrote in the description inserted by our molehill the plastic bars in the corridors of Mole, approximately 1 cm read look out across the floor. In addition, I have also done carbide into the holes. Whole 3 days of mole has can not be overlook. And now he digs merrily. Every time I have implemented bars. The mole now waiting not even 1 day to it becomes active again, but digging equal to about 20-30 cm next to the old hill his "new". Also the 1,4 kg bottle carbide, I ordered at the same time, does not deliver what it promises. Looking forward now about my garden residents and will grow into a flower meadow my lawn. The price of the Mole and mice Schreck is ok. Therefore only 2 stars!
