Answer: The easiest method is to wait and let the ladybugs take care of them for you. Another organic method is to knock them down with a blast of water from the garden hose. And of course you can gently remove them by hand. You spray them with commercially formulated insecticidal soap. Read and follow the label directions. Also, be sure you are not overfertilizing your roses as overfed plants will have excessively soft tender new growth that is extra attractive to the aphids.
