The NoMol Mole Trap is very effective at removing lawn damaging moles. They are extremely safe due to their underground placement. They have a plating that has proven to be highly rust resistant and ensures that your NoMol traps last for many years. The plating is dark green and blends in very well when placed in the moles' tunnel system. NoMol Mole traps come in packs of 4 and include wooden stakes and detailed directions for setting.
