"M. A. B." well remarks: "I believe that most of the trouble with insects on window plants comes from neglecting the great motto of the good housekeeper that a stitch in time saves nine.' It should be taken for granted that insects will certainly come to prey on the plants, and that when they do come there will be hard work to do. So I do not wait till they appear as an army, with the plant half devoured before I begin; but I syringe my plants with warm soapy water once a week lying them on their sides in the bath tub. At other times I sponge the leaves with warm soapy water, if there is no time for a full bath tub dose. Insects never trouble my plants".
