Which environmental factor could be used in pest control strategies?

Lowering humidity as a pest control strategy can be effective because many pests thrive in high-humidity environments. Certain insects, like mosquitoes and some types of mold, flourish in moist conditions. By reducing humidity levels, it can create an unfavorable habitat for these pests, leading to decreased populations.

Implementing humidity control measures, such as improving ventilation, using dehumidifiers, or altering irrigation practices, can help manage pest issues effectively. In contrast, the other options may have adverse or minimal effects on pest control. Increasing temperature or using artificial lighting may not necessarily deter pests and could, in some cases, encourage pest activity. Clearing land completely of vegetation might remove habitats and food sources for pests but could also disrupt the ecosystem and lead to unintended consequences.
