2. You find something sticky on the leaves - sap is especially appetizing for hungry aphids, as it has a lot of carbohydrates. Aphids tend to leave a gluey residue which is also known as honeydew. The substance attracts mold fungi and starts curling the leaves. With a range of different variety of aphids, you will have to choose a treatment option accordingly.

3. Scale insects - another very common problem apart from aphids are scale insects. Insects have to be taken care of before they become a greater issue.
