Tree caterpillar nests look like silken bags hanging in branches. You can either remove each nest by cutting the silken string at its top and then dropping the entire nest in soapy water or tear the nest open with a stick and let birds prey on the caterpillars inside. The pests feed during the day when the sun shines.
To get rid of scale insects prune and dispose of infested branches, twigs and leaves. When scale numbers are low they may be rubbed or picked off of plants by hand. Dabbing individual pests with an alcohol-soaked cotton swab or neem-based leaf shine will also work when infestations are light.
