Just make sure you DO check the bike periodically. Even with the airbox plugged mice will still build a nest under the seats if given the chance. One year I got a little complacent and even though everything was plugged I didn't check it for a couple of weeks. Mice had not only built a nest under my passenger seat, but they had gnawed a hole in the vinyl case that holds my tire plugging kit that I store under there. Now I make sure to also throw a packet of "Mouse Magic" repellent under the seats to keep them away completely and I set traps and bait stations around the bike just in case. It's a constant battle.
