How Quickly Do Mosquitoes Breed?

Backyard ponds can be kept free of mosquitoes with the help of mosquito fish.

Q: I leave my dogs at home in my yard when I go to work. I leave a kiddie pool partly filled with water for them to drink. I generally dump the water out and replace it every three days. Would standing water like this become a breeding area for mosquitoes? I’m worried because of all the recent publicity about diseases spread by mosquitoes.

A: Mosquitoes need more time than that to breed in standing water. If you’re changing the water that regularly, there shouldn’t be a problem. Water left for horses to drink also has to be changed every three days, too. If you’re interested in having a pond as part of your landscape, you can keep it free of mosquitoes as well by stocking it with mosquito fish (Gambusia affinis), which feed on mosquito larvae.
