The process does temporarily damage some leaves, I'd recommend you follow up with a permethrin based spray to get any that might've gotten into the ground.
Great advantage of this method is that no insect is resistant to sulfur dioxide. But neither are you; don't breathe the fumes unless if you want a killer headache.
