Mosquito hunting near Bear Valley California May 2018

Here are some photos of Josh Esposito doing mosquito control in the backcountry near Bear Valley. The vernal pools can sometimes hold tens of thousands of mosquito larvae. Cattle are trucked up for spring and summer grazing, and provide unlimited blood for the snow pool mosquitoes. But years of treating have cut the mosquito numbers way down. (Note that we have not seen any negative impact on the frog population.)
