It PAYS to SPRAY
There are several varieties of scale insects that attack many trees, particularly apple, pear, quince, vine, daphne, citrus fruits, abutilon and manuka. They do not move about in search of food, but build a tiny house over themselves where food is plentiful. The young are produced from eggs which hatch out in October or November. The general treatment to get rid of these pests is to spray with some oily material which will form a thin film over the shell and prevent the young from breathing. Red oil, emulsified, is one of the best sprays that can be used for this purpose, and should be applied when the trees are quite bare of leaves. In bad cases, two sprayings are often necessary.
