Oh, the Zombie Bees worked just fine. The players found themselves rescuing a little girl from a burning smokehouse and then having to fight some of the creeper's abominations as well as trying not to hurt the infected family members. At least one of the players was badly infected and needed serious treatment (as he started hearing the creeper whisper to him). People were leery when they figured out that the creeper had infected bees and quarantined the whole of the town.
It was great.
Also, they are very leery of the creeper, now. They've never met him, but they're very concerned about him. His constant use of minions to get at the players is beginning to bug them, I suspect. Which is how it should be.
