Answer: If your roses have aphids, you can wash them off with a strong stream of water from the hose. If the infestation is large, you'll probably be visited by ladybugs - they LOVE aphids! Any pesticide you use will kill the beneficial ladybugs as well, so be cautious in your approach to ridding your roses of aphids. A final method of control is the use of Insecticidal Soap, which will kill soft-bodied aphids, but won't harm adult ladybugs. Hope you'll try hosing the pests off first and save the Insecticidal Soap as a last resort.
