I'm really just curious. I've often wondered how people (usually
people with lots of money) who have large plots of land with
large ponds (or tiny lakes) control mosquitoes. I guess I'm a bit
of a pessimist, because whenever I think about the possibility of
having a large pond on my property (after I win the lotto and buy
a ranch) I think the number of mosquitoes would make it very
unpleasant.

So what do they use to control mosquitoes? Fish? Giant mosquito
"dunks"??!!

Fish are the best control, you won't find many mosquitos at all in
water inhabited by fish. You will find fat happy fish just waiting for
the next flush of mosquito larvae to appear.
In waters with no fish at all BT is usually broadcast as granules on
the water surface.
