Where should you target when spraying a lawn for fleas?

When spraying a lawn for fleas, focusing on shaded areas where pests tend to rest is the most effective strategy. Fleas thrive in environments that provide protection from direct sunlight and are cooler, such as shaded areas under shrubs, trees, or patio decks. These locations offer a humid microhabitat that is conducive to the survival of fleas and their eggs, making it essential to target them during treatment.

In contrast, open areas directly exposed to sunlight can be less favorable for fleas, as they are susceptible to desiccation and may not linger there as much. High grass areas can sometimes harbor fleas but are not as critical as shaded spots since fleas prefer cooler, sheltered environments. Flower beds and gardens may have some flea activity but are typically not the primary focus for flea control when treating a lawn, as fleas are more commonly found in shaded resting places rather than in flowering plants.
