Trapping a mole can be difficult. Flooding is not generally successful; many mole breeds are good swimmers and moles generally return to flooded tunnels as soon as they are dry. Poisoning the creatures is often prohibited by local health officials and can affect food if the mole problem is in a garden area. Trapping a mole with scissor traps or harpoons can be a bit distressing for those with a weak stomach. Use the jar method for a humane and successful catch.
Find the active tunnels in your yard. Moles burrow fast, leaving old tunnels alone. Step on a few of the tunnels, then check them a few hours later. Any tunnels that have been rebuilt are active. Collect a jar for each active tunnel.
Tape a piece of string with a piece of hard candy tied to it to the inside of your jar. Use a plastic 2 liter bottle if you do not have a large glass jar. Pick a jar that is deep enough that a mole will not climb out. Moles are generally 6 to 8 inches in length.
Dig a hole in each active tunnel deep enough to place your jar. The lip of the jar should be flush with the bottom of the tunnel. Rub the outside of the jar with soil to rid it of your scent. Place the cotton wool at the bottom of the jar to keep the mole from hurting itself when it falls. Cover the top of the tunnel with a wood board to hide it.
Check the trap every few hours. Once a mole is found, remove the jar from the hole and take the mole to a new area. Be careful not to get your hand too close to the lip of the jar as moles can be quite aggressive.
