Flea Bites vs Mosquito Bites: What’s the Difference

Although blood-sucking insects produce both flea and mosquito bites, there are some minor variations in the appearance and feel of these bites. Flea bites cause an itching welt on areas like the epidermis, ankles, and legs. Mosquito bites create a raised, painful pink mark on the skin that can, on rare occasions, trigger severe allergic responses.
