Learn How to Make Your Plants Unfriendly to Scale Insects
Treat Plants with an Insecticide Root Drench
Most scale insects have a preferred type of host plant that they will attach themselves to and feed off of for the rest of their lives. If you know that scale pests are common to such a plant on your property, applying a systemic root drench of an appropriate insecticide can offer significant protection against future infestation by sneaky scale insects of the same type.
Separate Plants that May Host Scale Insects
It may not always be practical with shrubs and ornamentals used as landscaping elements that could suffer from scale infestation, but in the case of potted plants or smaller ornamentals that can be moved, giving potential host plants some space away from other plants on your property can help to minimize the spread of scale insects.
Carefully prune away any branches that appear to be fully infested if other treatments have not worked to reduce scale insect presence on these plants. Be sure to dispose of any such clippings immediately, and do not use these pieces for compost.
