I saw on the show "Sons of Guns" (Red Jacket Firearms) where they modified a 10-22 and added a bayonet to it. Could come in handy if you actually run out of ammo or need to reload. Considering that one bite could kill you, I would want to keep some distance between them and me especially if you are talking about running into 50-100 of them at a time, if not more. Then you have to worry about running into "bad guys" who may want to take whatever they want from you. Some kind of club or sharp object will only work if that is all that THEY have, and once again, if there are a few of them, you are screwed.
