With the United States containing so many world-Â­famous tourist destinations and being home to three giants of the aviation industry (US Airlines, American Airways, and Delta Air Lines), it's no surprise that the country's airports rank among the busiest in the world, weaving a complex network of routes all over the globe.
Birds, bats and other animals can be used as one of mosquito control methods, but alone they certainly wonât make a visible impact on the population of mosquitoes. Some species of birds like purple martin eat mosquitoes and these insects take few percent of their daily meal and bats, who are night hunters also feed from mosquitoes.
Purple martins prefer to live in open spaces close to water, because they find lots of insects to eat near wetlands, swamps, and wet meadows. Purple martins are very used to humans and live in man-made birdhouses designed specially for them. Before martin houses, they lived at the edges of forests, in mountain forests, and deserts. Some purple martins in the western United States still live in these natural habitats, but most nest in man-made martin houses.
