1. Body Chemistry and Scent
Fleas are attracted to specific chemical compounds in human sweat and skin secretions. The unique mix of natural oils, sweat, and other chemicals on a person’s skin can make them more appealing to fleas. People with higher concentrations of certain chemicals are more likely to be targeted.
2. Blood Type
