How to Look Flea Bites on Humans, Methods of Treatment

Do you own a pet that is prone to these parasites? See your puppy scratching its ears? Time to be aware of fleas’ bites and learn everything about them: where, how dangerous they are, and what can be done about them.

Do Fleas Bite People?

Yes, they do. What they eat is blood. A flea may suck 15 times more blood than its weight, so the entire colony needs a lot to satiate hunger. Typically, they are found on pets, because fur is more comfortable for living, and people don’t notice pests and their bites right away, which allows them to increase population without being disturbed for some time. Besides, pets are more prone to these parasites, loving going through garbage, contacting with contaminated animals, etc.

As a rule, a human gets fleas when striking a pet, or just living with it – a flea can jump up to half a meter long, which is why it is easily transmitted from creature to creature. Why do fleas bite humans? The insect doesn’t care who serves as a source of food – animals, or people.

Characteristics and Pictures of Flea Bites

The problem is that sometimes it is very hard to differentiate flea bites from some other insects’ attacks. If you google some images of flea bites, you will see that these are small red dots 2-4 millimeters in diameter. Fresh bites are tiny, and sometimes people don’t even notice them. But when it starts scratching and skin irritates, redness appears around the dots, and they are easier to observe. They start looking like small blisters, and sometimes bubbles form.

Generally, flea bites on humans are located on ankles, lower parts of legs, waist and wrists – areas of contacts between humans and pets. It can also be explained by the fact that clothes are very snag to the skin in these areas, and causes irritation of bites.

Thus, the red spots are usually concentrated in certain body zones, which is why people can call it “flea bite rash”.


How can one know that what he or she sees are exactly flea bite symptoms? These may include the following:

  • redness around bites (its duration and severity depend on personal reaction to it);
  • itching and burning sensations in the areas of bite clusters;
  • allergic reactions that can be different, starting from slight dizziness and finishing by swelling of different body parts;
  • infections that result into worse complications like pains, swollen glands, etc.

And, of course, you may understand that your house is infested, if you see pets keeping scratching areas behind ears, tummy, etc.


How long do flea bites last? Depending on body reaction, redness can keep from several hours to several days. If you don’t scratch the bites, you will recover in a couple of days. Otherwise, it may take two-three weeks to get rid of the bites and their traces.

Flea Bites vs Mosquito Bites

It is very easy to mistake other insects’ bites for fleas’ bites. For instance, they remind of stings left by mosquitoes. Here is some information that will help you to understand what is what.

Do Fleas Transmit Diseases?

Inflammation and itching are minor symptoms that may quickly pass by, if a person has strong immune system and resistance to flea saliva. Although the stings of tiny insects may not even irritate people, they should be treated seriously. Sometimes, flea bite rash may lead to secondary infections and complications that are far harder to cure. Did you know that fleas can transmit numerous diseases, including:

  1. Cat scratch disease is transmitted by 40% cats, and can be passed to a human via fleas. Although the animals themselves do not suffer from it, it may cause strong itching, skin inflammation, high temperature and fever in people.
  2. Plague, being one of the oldest and most serious infections, can lead to fatal outcomes and health complications.
  3. Tungiasis is the infestation caused by female fleas laying eggs in upper skin layers of host. It may cause itching and burning. This disease is very hard to define visually. Although typically examined on feet and in the periungual region, the disease can also affect the entire human body.
  4. Various Rickettsial diseases as, for instance, murine typhus. This infection is accompanied by high fever, strong headaches, chilling, myalgia, nausea and weakness.
  5. Bartonelloses is a potentially fatal pseudoneoplasic disease (mortality rate is 25% roughly) that has such symptoms as malaise, fatigue, headache, loss of appetite, anorexia and enlarged soft lymph. Requires fast and effective treatment with antibiotics.

Thus, infected flea bites are potentially dangerous, because the insects transmit some diseases carried by hosts (cats, dogs, rats, etc.).


What makes flea bites on people inflame and itch is flea saliva that is injected into blood to numb nerves. It contains more than 15 different substances that may appear toxic for human body. Some people have certain proteins and immune system strong enough to resist the substances, so they may disappear without being noticed. But some people, especially children, are more prone to allergy. They tend to experience severe itching and extensive redness in best cases. In the worst, a bite may lead to anaphylactic shock. However, this is a 1 out of 10000 case. Other allergy symptoms may include:

  • hard breathing;
  • nausea;
  • dizziness;
  • chest pain;
  • tongue and lips swelling.
