This Pest-Stop tunnel mole trap, also known as a barrel mole trap, is a very traditional solution to a common garden problem. The trap is set, then placed in the mole run, and is triggered when the mole passes through it, killing it instantly. The dual setting means the trap is triggered whichever direction the mole enters from. Often used by professional mole trappers, it is manufactured from galvanized steel to prevent corrosion.
