A properly built and filtered pond will not attract mosquitoes. Any pond built with an adequate filter system will have a water quality that does not appeal to mosquitoes. For mosquitoes to lay their eggs, hatch successful larvae, and reproduce; they need and search for high nutrient, low oxygen, still water; in other words stagnant water. This type of environment is excellent for mosquito larvae which is why mosquito larvae can be found in everything from uncared for birdbaths to abandoned tires that have filled with rainwater.The pond installations performed by FSA&L have excellent pond filtration systems which create a water quality which is high in oxygen due to the beautiful waterfall designs we construct which mix large amounts of oxygen into the water. The FULL SERVICE AQUATICS pond installers in NJ also build ponds with plenty of water movement due to the pond skimmer systems we install with our pond construction packages, and our pond designs yield a very low nutrient level as well due to the biofalls filter system and the aquatic plant mix that breakdown and absorb nutrients from the water creating beautiful, clear, low nutrient water, and happy pond fish and koi. AND by the way, NO MOSQUITOES!!! In 15 years of pond construction in NJ and other parts of the country I have never once had a problem with any of our pond customers having to deal with mosquitoes due to a water garden installation performed by the backyard pond construction experts at FSA&L.
