response: In most cases, aphids cause little to no damage to plants and can be ignored. If aphids are causing problems, and it is necessary to treat them, you may want to consider using insecticides. Several insecticides are low risk to people, beneficial insecticides, and the environment. Neem (azadirachtin) is a plant based pesticide that discourages aphid feeding. Insects are not killed quickly, but it makes them stop feeding and they slowly die. Insecticidal soap, horticultural oil and pyrethrins can be effective at controlling aphids. Remember to spray the underside of leaves as well as the top. These materials will only kill aphids that they come in contact with. Repeat applications may be needed. Residual pesticides are effective for one week or more. While they are longer lasting, they also kill a variety of insects, including natural enemies. This can make aphid problems worse. Do not spray trees or shrubs that are blooming. Common examples of pesticides available to consumers include acephate, permethrin, bifenthrin, lambda-cyhalothrin, cyfluthrin and malathion. Systemic products, like imidacloprid and dinotefuran, are applied to the base of trees and transported through the sap to the leaves, stems, and branches where the aphids are feeding. When the aphids consume the pesticide, they will die. This process can take between two to four weeks depending on the product used and the size of the tree. Most of these products will also kill other insects feeding on foliage in trees. The use of systemic insecticides avoids pesticide drift, especially when treating large trees. Systemic pesticides don't directly contact natural enemies. However, imidacloprid and dinotefuran are very toxic to pollinators. Either avoid applying these insecticides to bee attractive plants or wait until the plants have finished blooming before treating them.  Read all pesticide label directions very carefully before buying and again before using to ensure proper application. Be sure that the label specifies it can be used on the specific plant you wish to treat. The label is the final authority on how you may legally use any pesticide. Whenever using any pesticide, including low impact, natural or organic pesticides, follow all label directions and use standard pesticide safety practices for transporting, storing, mixing, applying, and disposing of pesticides to protect yourself, your neighbors, and the environment.  Thank you for your question and have a great gardening summer.
