Do fleas live in the desert?

Yes, fleas can live in the desert. Although fleas generally prefer warm and humid environments, some species can adapt to arid conditions. These desert fleas have evolved mechanisms to survive in harsh environments, such as the ability to conserve water, enter dormancy during dry spells, and feed on a wide range of hosts, including reptiles and small mammals. For example, the species "Xenopsylla cheopis," also known as the oriental rat flea, is commonly found in sandy and desert regions of North America, Africa, and the Middle East.
