What role does humidity play in pest presence in gardens?

Humidity significantly influences pest presence in gardens by creating an environment that is conducive to their activity and reproduction. Higher humidity levels can lead to increased moisture availability, which is essential for many pests, particularly insects like aphids, mites, and thrips. These pests thrive in humid conditions as they are less prone to drying out and can feed more effectively on plants. Additionally, elevated humidity can promote the development and proliferation of fungi and bacteria that pests use for food or habitat, further increasing their populations.

While improved humidity may contribute to better plant growth conditions and reduce the frequency of watering, these factors do not directly correlate with increased pest presence in the same way that humidity does. Hence, the impact of humidity on pest activity is a crucial consideration for maintaining healthy gardens and managing pest populations effectively.
