Hi, firstly, bury your new traps in the same soil type as where the moles are,for a week.Make a run finder, a rod with a blob of weld at the end, rub your hands in soil before setting traps and keep the holes you make for the trap as neat as possible, if you get a mole still alive just apply preasure at back of its head(they have no skull here so instant death), try to harrow field before you start which makes the moles easier to locate. Moles wil have young about now so they are active, working morning then evening, once had two in the same barrel trap, father caught an albeno, hope this helps.
