An adult female mosquito (which is the only one that bites; males feed only on plant juices) lays between 100-400 eggs, and in 2-3 days those eggs hatch into larvae. The larvae are found in a variety of places; neglected swimming pools, storm drains, ditches, artificial containers, and ponds. However, the one thing all of these places will have in common is standing, stagnant water. Areas with standing water could have hundreds to thousands of larvae getting ready to mature to an adult and wreak havoc on backyard bbq parties across the country.
Yes, we did say ponds, however the ponds and water features we build, do not have standing water. All of our water features; ponds, pondless water features, fountains, have lots of moving water. This moving water eliminates the ability for a mosquito to lay eggs. You may find mosquitoes resting among your plants, shrubs, or grasses during the day, but that is not because of your water feature, this would be due to a different source that has standing water for a 4-7 day period.
