The American bullfrog is native to the Atlantic side of North America, from the Gulf of Mexico to Cape Cod in Massachusetts, but it is not present in large areas of Florida, Colorado, Nebraska, South Dakota and Minnesota. American bullfrogs have intentionally been introduced to new areas, such as fruit orchards, to control rodents and other pests. In the United States, it has been introduced in places such as Nantucket Island, Arizona, Utah, Colorado, Nebraska, Nevada, California, Oregon, Washington and Hawaii, mainly in the early 1900s.  American bullfrogs have been introduced to South America as well, where it is present at least in Brazil and Colombia. In Asia, it is found in at least China and Japan. In Europe, American bullfrogs were first introduced to France, but now it has also been found in the United Kingdom, Belgium, the Netherlands, Germany, Italy, Greece and in Denmark among the Nordic countries.
