How can landscaping be designed to affect pest populations?

Landscaping can significantly influence pest populations through thoughtful design that specifically deters pests while simultaneously encouraging beneficial species. This approach involves selecting plants that are known to repel certain pests and integrating them with others that may attract natural predators of those pests. For example, planting species that produce nectar or pollen can draw in beneficial insects like ladybugs and lacewings, which help control aphid populations.

Additionally, incorporating a variety of plants can create a more balanced ecosystem, reducing the likelihood of pest outbreaks. By fostering an environment that promotes biodiversity, the landscape becomes less conducive to pest infestations because it disrupts the monoculture that many pests thrive in. This holistic strategy not only diminishes pest populations but also enhances overall ecological health in the landscape.

Other options do not align with effective pest management principles. For instance, using only non-native plants can lead to an imbalance, as these plants may not support local wildlife or maintain pest control. Similarly, creating dense plant coverage might provide shelter for pests rather than deterring them. Minimizing plant diversity can also create an environment where pests can flourish, as it often leads to an increase in specific pest populations by reducing the presence of their natural enemies.
