I too worry about those big giant mosquitoes we have down here. A couple of generations back most of my forbearers were killed by yellow fever spread by mosquitoes. My Dad got malaria down here. I am suspicious of them and wish DDT would come back. That ban has been a disgrace.
The ban on DDT has indirectly killed more people than AIDS has, especially in developing countries (although that is changing rapidly, as evidenced by stories such as this).
