Where are you most likely to find fleas outside?

Fleas thrive in environments that provide shelter and protection from direct sunlight and extreme temperatures. Shady areas offer the moist, protected environment fleas prefer for their survival and development. In shaded spots, fleas can find ample organic matter, such as decaying leaves or vegetation, which serves as their food source and habitat. These conditions help them maintain the necessary humidity for their lifecycle and protect them from desiccation.

Sunny areas, while potentially habitable for a short duration, do not provide the consistent moisture that fleas require. Near water sources could support other forms of pest life and breeding grounds, but fleas do not tend to congregate there in significant numbers as they avoid wet conditions that could disrupt their lifecycle. Open fields might offer space but often lack the necessary cover and humidity that shaded areas provide, making them less suitable for fleas. Thus, shaded areas are the most conducive to flea populations thriving and reproducing outdoors.
