Neglected or "Green" Pools

What is a "green" swimming pool?

A "green" swimming pool is a pool hat has been neglected and has resulted in the build up of pool algae. These pools attract mosquitoes who breed and could multiply into the millions. Mosquitoes need only a 1/2 inch of standing water to breed and turn into biting adults. Mosquitoes could carry the West Nile virus and other diseases that harm humans, and therefore green pools are a public health threat.

If you see that your neighbor has a neglected pool which has attracted pool algae, please report the issue to prevent the breeding of mosquitoes.

How do I prevent my pool from becoming a"green" pool and control mosquito populations on my property?

Operate filter and skimmer everyday to remove egg rafts and larvae. Provide drainage for filter and pumps. Chlorine will NOT kill mosquito larvae. If a pool cover is used, keep it tightly sealed. Remove rainwater from the top of the pool cover. Stock "out-of-order" pools with mosquito fish.

The Orange County Mosquito and Vector Control District provides FREE mosquitofish to all Orange County residents for placement on their property only.  Residents can pick up fish at the District or may have a service request generated by phone or online to have them delivered. These fish are routinely stocked by the District to control mosquito populations in sources such as artificial lakes, irrigation ditches, and industrial ponds.

Please visit OC Vector Control's website here for a mosquito fish request form.
