Also, dig a small pond. An old bucket sunk in the ground will do, just an area of standing water. This will rapidly become a breeding ground for insects.

That sounds like a bad idea if you don’t like mosquitoes.

The problem is "we don't like mosquitoes" so we have eliminated their breeding areas, consequentally we have eliminated the breeding area of a host of other insects. So, now we have no insects, so either we put up with mosquitoes or we put up with environmental catastrophy, or we come up with $newidea that solves the problem. Do you have an instance of $newidea to avoid mosquitoes?

Also illegal to do in some communities

Interesting - I've never heard of that, can you point me to some specific instances where that's banned?

I want to say most counties down in the Phoenix area have rules against it. I easily found Maricopa county rules and with time could find more

Chapter III, Regulation 2, of the Maricopa County Health Code states:

"No person shall cause, maintain, or within his control, permit any accumulation of water in which mosquitoes breed or are likely to breed. The owner, occupant, or person in control of any place where mosquitoes are breeding, or which constitutes a breeding place for mosquitoes shall take all necessary and proper steps to eliminate the mosquito breeding and to prevent its recurrence . . ."
