Effectively combat aphids
Since last year I have been destroying aphids with hairspray. They then stick immediately and can not spread further.
This works for almost all plants, except those that have very thin and delicate leaves, so you should only spray the stems. Since hair spray is also used in humans, I assume that there are no extreme toxins in it. If necessary, the treatment must be repeated, but after the second time all aphids are actually gone.
