- 1). Check your lawn carefully for signs of a vole or mole problem. Look at the leaves and vegetation on all plants for any chewed pieces, which may indicate a problem with voles. Moles leave behind tunnels and molehills.
- 2). Stick the end of a broomstick into the top of a mole tunnel, pushing down to make a small hole in the top. Alternatively, push your shoe into the hole until the top indents, but doesn't collapse entirely. Wait at least one day, and then check the area. If the indent is now gone, it proves that moles are still using the tunnels.
- 3). Use a shovel to break the surface of the tunnel and get inside. Remove dirt from the bottom of the tunnel, creating a space for the trap. Smooth back the dirt to make the bottom of the tunnel level and to keep the rodents from noticing the changes you made.
- 4). Push the kill trap into the hole you made earlier. The traps consist of a series of spikes, on top of a central runway. When the mole or vole runs across the trap, the runway snaps and the spikes drive into the animal's body, killing it instantly.
- 5). Leave the kill trap alone for at least 24 hours. Check it the following day and continue checking it for the next few days. If the trap is still in place without any catches, move it after four days. Use multiple traps if you think you have more than one mole or vole in your yard.
