Scale insects are among the most common pests of houseplants and plants on the balcony and in the garden. They damage the plants by sucking out their nutrient-rich sap, which in the long term leads to the death of the plants. To prevent this, it is advisable to fight scale insects. With these simple tips and natural home remedies, a scale insect infestation can be quickly controlled – without any chemicals at all.
How do I recognize a scale insect infestation?
Scale insects have a shield-shaped body with a brownish or white color. The aphids appear especially in winter, when they find shelter and food on the plants to overwinter. They hide on the undersides of leaves, stems, young shoots and in shoot axils.
As scale insects suck plant sap, which contains protein and sugar, they secrete a clear, sticky liquid called honeydew. If this honeydew is visible on leaves, stems and around the plants, such as the flower pot or floor, it is recommended to take a closer look at the plant. Ants are also attracted to the sweet honeydew, which may indicate an aphid infestation. In case of light infestation: remove scale insects In case of a weak scale insect infestation, it is often sufficient to wipe the animals away with a damp cloth. A tooth
brush is also suitable to reach the shoot axils and areas between closely spaced shoots well.
