Following the principles of Integrated Pest Management (IPM), so far we have talked about clearing away the plants that harbor them, and sources of standing water, where the lavae grow. Now it is time to look at mosquitoes natural predators, and how to attract them.
A good first step, paradoxically, is to establish a pond. Remember, mosquitoes don’t lay their eggs in ponds, because there are too many predators? So, if you can, make a pond. If you already have one, enjoy!
Ponds will attract dragonflies, which feed on mosquitoes. They like aquatic plants in and around the water, so they can hide and breed. Ponds also attract fish that eat mosquitoes. Beware, however, of the nicely named “mosquito fish.” It is an invasive species, and if it can escape from the pond, will spread like the snakehead fish.
Bats need water, too, and they eat a lot of mosquitoes. To attract bats you could set up a bat house. These need to meet certain requirements. Much easier to do, is to have less outdoor light, so that the bats feel more at home.
Among other birds that feed on mosquitoes is the purple martin. These interesting birds have forgotten how to make their own nests, and so are dependent on humans to do this for them. They tend to like groups of gourd-shaped nests.
And while you’re setting about attracting birds, put in plants that are native to your local area. These will support the caterpillars that baby birds need, until they, too are old enough to fly around catching mosquitoes.
