Gloucester had been reduced to 14-men as early as the third minute when Adam Eustace was red-carded for violent conduct, although it was Gloucester – coached by former Wasps boss Nigel Melville – who scored the first try of the game.
That came via Samoan centre Terry Fanolua, adding to a penalty from French fly-half Ludovic Mercier after Wasps had taken the lead with a Kenny Logan penalty.
Wasps’ Kiwi fly-half Mark Van Gisbergen got the home side back on track after 26 minutes however with their first try – the next score not coming until after the half-time interval.
When it came it was in favour of the home side with another Logan penalty, followed up almost straightaway by their second try – England Sevens wing Josh Lewsey the scorer to put them further ahead.
Logan converted that score, but Gloucester refused to lie down, Mercier hitting another penalty, although when recalled England lock Simon Shaw went over for Wasps’ third try with eleven minutes left on the clock, the result was beyond doubt.
Gloucester fought on, but their only reward was a penalty deep into injury-time from England Academy centre Henry Paul, as the 14 men tried in vain to reap even a bonus point for their efforts.
