Perhaps not permanently but quickly
USDA recommends
1T of liquid dishwashing soap--the brand doesn't matter
1 c vegetable oil. Scientists believe that canola oil repels insects by altering the outer layer of the leaf surface or by acting as an insect irritant. Canola oil appears to have no adverse effects on humans or the environment. Soybean oil is widely available and has demonstrated good to moderate control on many species of pests. Soybean oil can also aid in suppression of powdery mildew.
When you're ready to spray, add one or two teaspoons of the oil-and-soap solution to a cup of water. Pour that into a sprayer and shake well.
Do not spray when temps are above 80 degrees Fahrenheit! Your plants may "burn" or have a reaction to what you are using in excessive heat. This is known as "phytotoxicity."
Some liquid soaps will harm plant tissue just like they harm insects - by cutting the waxy coating on the organism’s skin and causing it to dry out. Commercial insecticide soaps will not do this. Safer makes this product.

Lady birds are predatory beetles but it is really the juvenile stage that does the most pest control. An adult female Lady Beetle may consume up to 75 aphids a day while the smaller male may consume up to 40. One larva may eat up to 350 aphids during its life span.
While it will, in the long run, help your problem getting the beetles established and reproducing takes time. The females deposit their eggs in clusters of up to a dozen per mass. The larvae hatch from the eggs in about a week and immediately start to consume aphids or other appropriate food. In a little less than a month they pupate and the pupal period lasts only about one week. When the adults emerge they too feed on aphids, but as fall approaches they may eat some pollen which supplies fat for winter hibernation.
The juveniles resemble tiny, six- legged alligators, blue-black in colour with orange spots. They are only 1/4 inch long.

Aphids are the best, but if they don't stay in your yard---
get a clean spray bottle. Fill with water and a few drops
dish detergent and a few drops of tobasco or hot sauce.
Spray generously on the rose petals Upper and lower, about
every days.

Well organically, there are places that sell ladybugs. Ladybugs love to eat aphids, but there also are a variety of insects that love to dine on aphids.

Spray dish soap mixed with water on them. I have tried that and it really works! Or, you can try buying some ladybugs at ZamZoes, they sell them and they can rid the aphids for you.

If you crush them on the plant, the smell will attract bugs that like to eat aphids. They will keep it under control for you. There are also organic oil sprays that will kill adult, juvenile, and eggs of aphids.

They will always be around but, buy ladybugs and place them in your rose garden. They love those tasty aphids. Ask how to purchase them at any garden center.

Mix a little plain (not disinfectant type) dish soap and water and spray on all the leaves both on top and underneath, also the "ladybug" idea works great, or you'll have to go out and pick them off which is tiresome and yucky!

take a couple of cigarette butts, say 6 to a quart of water, soak overnite, spray. There is enough nicotine (poison) even in the butts to do a great job on eradicating aphids. Works great for me.

Two previous answers should work the best. A light soap and water in a spray bottle and spray both sides of the leafs and the ladybugs.

plant onions and/or garlic around the roses. they make the leaves of the rosebush more acidic. aphids like sweet plants. you can try ladybugs and soapy water too.
