They're not a pest, they actually help aerate your soil, getting water, oxygen, and nutrients to your plants' roots, as well as serving as tasty meals for frogs and birds.
I wouldn't usually have bothered, Meriad, but in my case, they had actually destroyed a small patch of lawn - the grass had died, the patch was becoming bare and unsightly. I didn't want them spreading.
