> making sure there's no stagnant water[...] A couple of months ago I found mosquito larva in some stagnant water in a parking garage, and made sure to pore some bleach into that stagnant puddle when I returned. I've wondered if the opposite of the "no stagnant water" advice wouldn't be more effective in countries that suffer more from mosquitos. I.e. intentionally create ideal breeding ponds for mosquitos, then kill…
This assumes that the new ponds will pull mosquitoes away from existing ponds. Is this true? (Maybe mosquitoes are limited by suitable breeding grounds, and introducing decoys could have no effect.)
So this would work for the same reason the more high-tech release of sterile mosquitos works, it robs them of a breeding opportunity.
But perhaps I'm misunderstanding your question...
