Make sure you attached the trigger to the trap with some cordage, weather them well because there easier to set when slightly rusty and set the trigger slightly further away from the jaws than the instructions tell you cause this stops the mole been caught by its front feet. Good luck [bANNED TEXT]
I don't think to weather the trap is the way to go. The triggers set easy if you put them in square and I think it would push over easier without rust to hinder the process...
I Might be wrong and it won't be the first time.
