aphids - Knowledgebase Question

I have sprayed my hybiscus bushes three times and they are still covered with the white flying aphids. You touch the bush and it looks like a snow flurry. Once with a garlic/oil mixture and twice with a spray I purchased from Home Depot specific to aphids.

Generally aphids won't fly away when they are disturbed. Instead of aphids, I think you are dealing with an infestation of whiteflies. They are harder to control than aphids because they fly away, but Insecticidal soap applications will eventually do them in. The key to control is to spray in the early morning or early evening when they are resting on the plant and not so likely to fly away. Spray thoroughly, repeat according to label directions, and be sure to spray the undersides of the leaves where they lay their eggs. It will take time and patience but you'll eventually get control of those pests.
