FYI

Effects on nontarget vertebrates are considered during the US EPA registration process. Synthetic pyrethroids are probably the most widely used group of insecticides for control of adult mosquitoes: http://www.epa.gov/pesticides/citizens/pyrethroids4mosquitos.htm

"Pyrethroids used in mosquito control programs do not pose unreasonable risks to wildlife or the environment. Pyrethroids, when applied at mosquito control rates, are low in toxicity to mammals, and are practically nontoxic to birds. Mosquito control formulations of permethrin break down in the environment, and high temperatures and sunlight accelerate this process. However, pyrethroids are toxic to fish and to bees. For that reason, EPA has established specific precautions on the label to reduce such risks, including restrictions that prohibit the direct application of products to open water or within 100 feet of lakes, streams, rivers or bays."

Allegations of pesticides harming wildlife should be referred to the appropriate regulatory agencies.
