So, I get that EEE is a seemingly dangerous disease, and I’m not an expert at mosquito diseases, but in 2015 more people in Michigan died from vehicle collisions with deer than this disease caused this year. I did take general ecology though and remember learning that if you kill off 99% of the skeeters, and there’s just 1% left, they might be immune to the pesticide, and then they reproduce... I guess maybe I missed the part where this spraying was going to eliminate EEE?
Also - Is it just BTI to be sprayed - where did you see that? Its a combo of several diff pesticides (see any article on it).
