Answer: Mosquitoes breed in stagnant water and in mud. To reduce the number of mosquitoes you will need to limit their breeding areas. You might try stocking the ponds with fish to eat the mosquito larvae, and also add the mosquito dunks (these contain Bt) to control them there.
You might also want to look at the drainage patterns in the area and make sure there are no stagnant puddles or swampy areas where they might breed. These can sometimes be corrected by improving the drainage plan.
Make sure there is no standing water in places such as clogged gutters or downspouting, chilren's wading pools or toys, saucers under plant containers, tarps over wood piles, neglected birdbaths and so on.
Finally, a screened in porch may be helpful if you want to sit outdoors for extended periods. And, the CDC recommends wearing long sleeved shirts and long pants and/or using insect repellent to prevent bites.
Your local county extension office may also have suggestions based on a more detailed understanding of the situation in your subdivision.
