What areas should be treated when treating a lawn for fleas?

When treating a lawn for fleas, focusing on shaded areas is particularly important because fleas tend to thrive in environments that offer protection from direct sunlight. Shaded areas provide a cooler environment that helps maintain moisture levels, which are conducive to flea survival and reproduction. Additionally, these areas can serve as resting spots for adult fleas and their larvae.

While sunny areas might seem like they would be less hospitable to fleas, the critical concern is that fleas prefer locations where they can escape heat and dryness, which shaded areas provide. Open fields may not be densely populated with fleas since they lack the cover and humidity that fleas typically seek. Watered patches, although beneficial for plant health, do not directly correlate with flea populations; fleas are more likely to be found in places that offer shelter and moisture retention rather than directly in areas that are consistently wet. Thus, paying attention to shaded areas maximizes the effectiveness of flea treatments in reducing their population.
