What signs indicate an insect infestation in ornamental plants?

Visible damage and the presence of pests are key indicators of an insect infestation in ornamental plants. When plants are infested, they may display various forms of damage such as wilting, yellowing, or browning of leaves, distorted growth, or even holes in the foliage. Additionally, the actual pests, whether they are insects or their signs (like webs or excrement), can often be observed on or around the affected plants.

Healthy leaves and strong growth, increased flower production, and absence of stress symptoms do not indicate an infestation; rather, they suggest that the plants are thriving and not experiencing any significant issues. In contrast, visible damage and the presence of pests are clear signs that intervention may be necessary to protect the health and vitality of the plants.
