In terms of clearing moles as opposed to catching them you need a 12 bore and a small spade! I work on a farm and have moles popping up all over the place. Last summer I got over 50. Flatten all the hills first. Then on sunny/bright/windy days walk or quad around until you see fresh hills that are moving. Approach from where you think he isnt so you're about 2m away. Wait until you see him moving and fire where you think he is. Dig like a fool and hey presto. He's either in bits or stunned/dead from the shockwave. Takes some practice but it's the most effective way we've found to get rid!
