Snippet: During their life cycle adult mosquitoes must travel between breeding grounds and resting places. Researchers exploited this trait by disseminating a safe and persistent insecticide called pyriproxyfen in the areas where adult mosquitoes rest. The insecticide is neither lethal nor repellent to adults.
The adults then take the insecticide to breeding grounds. This strategy ensures a strong, wide coverage of aquatic breeding sites by treating only a small portion of the adult resting areas because adult mosquitoes move around so much.
Lets see if further trials are successful and gain greater publicity,personally I have never heard of this source before.
