You'll need a metal probe, about 5 mm in diameter to locate the mole tunnels. Once you've found this, you can use a suitable trap which can be carefully set in the run. Be sure to cover this with earth, excluding all light snacks air.

That's it, you're ready to catch a mole!

Check the trap every 24 hours. If nothing has been caught within two days, re-locate the trap to a different part of the tunnel. Practice makes perfect - the more often you do it the better you'll get and the more moles you'll catch!
