Why some people get more flea bites?

Some people get more flea bites due to individual differences in body chemistry, which can attract fleas more than others. Factors such as body heat, carbon dioxide emission, and skin bacteria can influence how appealing a person is to fleas. Additionally, certain people may have skin that is more sensitive or reactive to flea saliva, leading to more noticeable bites. Lastly, environmental factors, such as spending more time in infested areas, can also increase exposure to flea bites.
