Insecticidal soap is used to control many plant insect pests. Soap has been used for more than 200 years as an insect control. [1] Because insecticidal soap works on direct contact with pests via the disruption of cell membranes when the insect is penetrated with fatty acids, the insect's cells leak their contents causing the insect to dehydrate and die.

Adult winged aphids have a black head and thorax, and a yellowish green abdomen with a large dark dorsal patch. They measure approximately 1.8 to 2.1 millimetres (0.071 to 0.083 in) in length. [3] The wingless adult aphids are yellowish or greenish in colour, with the possibility of medial and lateral green strips being present.
Aphids do best when amino acids are actively translocated in the phloem. In spring, the leaves grow and import amino acids via the phloem; in summer leaves are mature and export mainly sugars. In autumn, the leaves senesce and export amino acids and other nutrients. Thus on trees the leaves are most suitable for aphids in spring and autumn.
