How Do Fleas Bite?

Fleas are small insects that feed on blood. They have long needle-like mouthparts and use them to pierce the skin to reach blood vessels deep within. These tiny parasites can cause discomfort and even ensnare humans, which is why it is important to prevent flea infestations.

Fleas live in warm, dry areas, and are generally found in tropical regions. Adult fleas are a parasitic insect that is usually only visible under a microscope. Their bodies are covered with bristles, and they have three pairs of legs, including a hind pair that is longer than the rest. This gives them good jumping abilities and allows them to move in and out of the hair on animals.

Flea bites are usually red and unsettling. In some cases, the bite may feel like a little pimple. It is important to see a doctor if the swelling is severe or persistent. Some people may experience an allergic reaction and require antihistamines. For severe cases, a visit to the emergency room is recommended.

Flea bites usually occur on lower legs and ankles. They are not as painful as mosquito bites, but can become red and itchy. The resulting swelling may last a week or longer. Flea bites may be localized or generalized. Household pets, livestock, or rodent infestations can all increase the risk of exposure to flea bites.
