If you have an ornamental pond or pool, mosquitofish may help to control mosquitoes. Mosquitofish, also known as Gambusia, are small predatory fish that eat mosquito larvae.

Multnomah County residents can get free mosquitofish from May 15-August 30.

Call 503-988-3464 or email vector.nuisance@multco.us to schedule a pick up time at our office in North Portland.
