A less high-tech way to reduce mosquitoes in your own back yard is to set up an attractive nesting location, such as a bucket filled with plant cuttings and water with protection from the rain, and putting Bti(Bacillus thuringiensis subspecies israelensis) in it. Bti will kill the larvae after they hatch. You can buy Bti pretty easily, usually in a dehydrated form called mosquitoes bits or mosquito dunks. Make sure to remove other potential nesting locations or add Bti to them too.

I am not an expert, but the last time I looked at this kind of thing what I took away from it was that you're not really doing anything to negatively impact the total mosquito population, you're just creating a new nesting site that won't produce adults. My understanding was that while it might feel good, it is not actually doing much to impact the population.

Apparently mosquitos don't really migrate. They get migrated by wind, but otherwise they stick to a relatively small radius. The idea with these is that you can reduce the hyperlocal population, like in a patio area. I use them on my property. It's not a silver bullet, but I can spend most nights outside without being overwhelmed as long as I maintain them.
