Organic controls white aphids on TC blackberries?
I thought I saw something that looked like a pure white aphid on my blueberries last week, but the thing jumped so quickly I figured that wasn't it. Just noticed rugose leaves and white "webby" stuff (not sticky) on the canes of nearby TC blackberry, some more of these quick-moving white jumping/flying bugs I think are aphids (shaped like the light green aphids I'm used to, had on tomato plants from nursery 2 years ago, but bigger).
What can I do NOW to get these under control? Ants might be farming them.
