Google announced on Google+ that you can now easily filter out traffic from bots and spiders from showing up and being tracked in your analytics.

Selecting this option will exclude all hits that come from bots and spiders on the IAB know bots and spiders list. The backend will exclude hits matching the User Agents named in the list as though they were subject to a profile filter.
