My intuition is that you are correct: the bucket doesn't eliminate all breeding grounds. It's a numbers game: you want to lower the population as much as possible. If you reduce the population enough, nature has the opportunity to handle the rest, since mosquito reproduction is also a numbers game: mates have to locate one another. This also frustratingly means it won't be an instant solution even if it eventually works. It takes a few generations to realize the benefits of the lowered population.
