Garden Moles

[Steve]

How do I get rid of them they are ruining my lawn?

My experience of ultra-sonic and other deterrent devices has not been good so the best solution is probably to find a mole catcher in Yellow Pages and pass the problem to him. (Some use humane traps; some poisoned bait. So check, if that is important to you.) DIY methods using traps can be effective too but they aren't easy, even if an expert has shown you what to do.
