I have had difficulty setting the trap. Mounding beneath the trip lever is critical-i'm still experimenting with the technique. I agree the instructions could be clearer. After 4 days of monitoring, I have caight 1 mole.
Set the traps per the instructions. Covered them with 5-gallon buckets to block any light getting into disturbed area and to keep pets safe. Next day, mole caught. Done. $50 for three traps versus a $150 cost for pest service removal of a single mole. And next time will be free!
