Fucking wasps are nasty at any time, and Rage was quite within his rights to try to eradicate the buggers. Obviously Nick didn't have the brains to find out what Rage was doing, and assumed it was something that was some sort of vandalism. Well, we all know when you 'assume', you make an 'ass' out of 'u' and 'me'.
Yeah, I think Rage will find something, it's a pity he had to be put through this shit.
