What is the most likely factor that can prevent future pest problems when installing an interiorscape?

When considering factors that can prevent future pest problems in an interiorscape, low light conditions play a significant role. Many common pests thrive in environments that are well-lit and have appropriate temperatures. By installing plants in low-light conditions, you're creating a less favorable environment for pests that prefer bright, illuminated spaces.

Pests like aphids, spider mites, and whiteflies are often attracted to plants that receive ample light, as these conditions can lead to an increase in plant vigor and density, which are ideal for pest establishment. Therefore, by managing light availability—either selecting shade-tolerant plants or limiting light exposure—you can reduce the likelihood of pest infestations.

In contrast, high humidity, frequent watering, and excessive fertilization can create ideal conditions for pest proliferation. High humidity can encourage mold and fungus, which may attract pests, while frequent watering may lead to root rot and stress the plants, making them more susceptible to pests. Excessive fertilization can result in lush plant growth that is also more enticing to various insects. Thus, while those factors can impact plant health, it is low light conditions that are most likely to serve as a preventative measure against future pest problems in an interiorscape setting.
