There have been reports that the larvicide pyriproxyfen might actually be causing microcephaly. Do you think this is a reliable claim?
I would encourage sticking with more credible sources. There are WHO documents supporting the use of pyriproxyfen in water in many nations further back than 2008. These birth defects have not been reported in other areas. Therefore, I do not believe this larvicide as possibly causative should be discussed at this point.
