Aphids are small, soft-bodies insects about the size of rice grains.
They are usually light green or black with a white wooly coating. Aphids survive by sucking the juices of soft new growth which damages a plant's ability to properly process food. Control ant population. Ants rub the bellies of aphids causing them to excrete honeydew, which the ants eat. So, control the aphid infestation by setting ant traps or destroying ant colonies.
