I ended up building this entirely by accident. Last summer I wanted to have aquatic plants in my garden, so I made a small container pond.
As you can imagine it quickly got invaded by mosquito larvae. By the time I realized I was getting raided by mosquitos each night, much more than previous years.
After getting hold of the bacteria (not sure if it's completely allowed here, only Amazon would sell it to me) mosquitos are completely gone, in the pond and around.
Other natural solution is having either fish, ducks, dragonflies, frogs, toads or other of the many things feeding on mosquito or their larvae
You can also add some small fish — many species of fish think that mosquito larvae and pupae are delicious.
I added 6 mosquitofish to my 110 gallon container pond two months ago. There are now nearly 100 in there, and the mosquito count in my back yard has definitely diminished.
Cool mosquitofish facts:
- An adult female can eat between 300-400 mosquito larvae in a single day.
- They're highly tolerant of low-oxygen and high-temperature water. They're hardy fish.
- They're native to North America, so pose little risk to getting into the water system, as they're already there.
- They're so effective at reducing mosquito populations, some local governments give them out for free.

I would be surprised if it isn't allowed anywhere. This bacteria has been known about and well studied for many decades and the cry toxin it produces has been bred into numerous crops starting 40 years ago.
