I have had a mole problem for years and have tried all the suggested solutions including castor beans. I also used the traps that have the blades that stab into the ground - thumbs down! After researching this I decided to try the Victor 0631 Out of Sight Trap. After setting the trap, I was on a ladder the next day cleaning windows on my house when I heard the trap go off. It went off with such force that it knocked over the flower pot that I had over it. And yes I got the mole. A few things to realize here. One, you need to be fairly strong to set it - it's not that easy. Two, preparing the tunnel site for placement of the trap is of paramount importance. If it's not prepared properly. it will not work. There are a lot of You Tube demos showing how to do this. Three, the mole will likely still be alive when you pull the trap out of the ground so be prepared to administer a blow of mercy. Fourth and final, I wondered how many moles I had and how long it would take to get them all. My experience seems to indicate that the mole has a fairly large territory so it's likely you may only have one as I did. I have about an acre of land on my property. If you have a mole problem this is the trap for you.
