This reddish-brown color aphids are giving problems they attack the old leaves.

The greenish aphids do not give much harm to my plants except a bit crinkle leaves but the black one destroy many flowers. They nest inside the flowers and hard to find them.

Insecticidal soap do much harm to the plants such as flowers dropping. So I stop using it and manually I kill them.

Any advice and opinions are very welcome.
