I purchased (3) of the traps. The instructions for using the traps are very difficult to underswtand. I have sandy soil and the instructions for this soil made no since to me. I have found the active tunnels and have set all (3) traps. After 2 weeks none of the traps have been tripped. I have moved the traps to different tunnels, set the traps at different depths with no success at all. Meanwhile the moles continue to devistate my yard. I am going to attemp to return the traps and do not recommend them to anyone.
