How can landscape design contribute to pest management?

Landscape design plays a significant role in pest management, and using plants that repel insects is a highly effective strategy. Certain plants, known as insect-repelling or pest-resistant plants, emit natural compounds or have physical characteristics that deter pests from feeding or nesting in the area. By strategically incorporating these plants into the landscape, it is possible to create an environment that reduces the presence of pests without relying solely on chemical interventions. This approach not only aids in controlling pest populations but also enhances biodiversity and can improve the overall ecological health of the landscape.

The remaining options do not contribute positively to pest management. Incorporating only decorative plants may neglect the utility of certain species that provide pest resistance. Providing more shelter for pests would likely exacerbate pest issues rather than mitigate them. Promoting urban sprawl does not align with effective pest management principles, as it can lead to habitat destruction and increased encounters between humans and pests. Thus, choosing plants that naturally repel insects is an essential aspect of thoughtful landscape design aimed at sustainable pest management.
