There is a method for doing this. I can't seem to find the original article where I heard about this, but it was tested in some remote area in Africa and had a 90% reduction in mosquito population with just one application. Here is a more updated Zika flavored article about the same technique:
I'm only aware of the test conducted in Brazil, which had a claimed 80% reduction rate:
Oxitec, which is owned by Maryland-based Intrexon Corporation, tested its mosquitoes in the small Brazilian city of Piracicaba and said the reduced the number of mosquito larvae by 80 percent in one area.
