According to the physical examination and patient’s history, a medical professional may diagnose a flea bite on a human. Although laboratory tests cannot confirm whether fleas are the cause of an individual’s allergic reaction, these organisms can be identified by vacuuming debris and bedding materials.

In this article, we will discuss all about flea bites and how to treat flea bites on humans, including some natural remedies.

Where Do Fleas Live?

There are over 2,500 different species of fleas in the world, including 300 in the United States. Fleas are tiny, parasitic insects that live in the homes of mammals and birds. Adult fleas are approximately one-fourth of an inch long and are dark brown or black. Fleas live in warm, dry environments.

Fleas also reside in carpets, soft furnishings, and soil. The presence of fleas will result in a high chance of having flea bites on your pets.

Flea Bites and Pets

The first thing to do if you notice flea bites is to check for adult fleas on your pet’s hair. You may also notice fecal matter on your pet’s comb. This is the flea’s digested blood, which looks like black pepper. If you notice it, you should consult your veterinarian. In severe cases, the disease may even be fatal. While treating a flea infestation is the best way to ensure that your pets are safe and free from infection, preventing symptoms of infestation is the key.


If your pet has an itchy flea bite, apply a paste of baking soda to soothe the skin and reduce itching. You can also apply ice cubes or frozen vegetables to the area. Apply the paste to the affected area twice a day for three to four days.

Flea Bites On Humans

When you suspect a flea bite, check your skin for any signs of blood loss. If you’re unable to find the source of the infestation, the first thing to do is consult a doctor. In severe cases of flea bites on humans, flea bites can cause serious infections. You should also check for symptoms like fever, blisters, and pus-filled boils.

However, you should not panic. Just remember to keep the affected area clean and covered at all times. After flea bites, you should take anti-inflammatory medications or antibiotics to prevent further infections.

Flea Bites on Humans – Diseases

Fleas can transmit various diseases to humans. You should also consider hiring a pest control company to get rid of the infestation. They can carry diseases such as typhus, plague, and flea-borne fever. They carry dangerous diseases like typhus and bubonic plague. Some of the infections these fleas can transmit include tularemia and bubonic plague, which are transmitted by their saliva.

How to Distinguish Flea Bites on Humans?

Fleas are tiny red lesions on the body. They are often difficult to distinguish from other insects but can be identified by their wingless appearance and the specks on your clothing that they leave behind. Mosquitoes usually bite at dusk, but adult fleas can be found at any time of day. While ticks usually infest cats, they can also bite humans.

Flea bites on humans can be distinguished with a visit to a veterinarian; they will identify the type of insect that bit you. The doctor will check for any signs of infection as well.


Symptoms of Flea Bites in Humans

There are several different symptoms of flea bites in humans. Most of these are harmless, but for some people, the bites can cause significant reactions. Flea bites may cause itchy, red bumps, blisters, crusts, and even hives. Symptoms of flea bites can vary between individuals, but it is important to take action as soon as you notice any signs of it.

Red Bumps

Fleas typically bite humans in the legs and ankles. A flea bite will produce a red bump on the skin that will begin to itch and become increasingly irritated. These bumps may swell or be filled with pus. It may remain infected for a week or more, and itching may be localized or widespread.

Itchy Skin

The main symptom of flea bites is itchy skin. You may notice a halo around the red bump; similar to a mosquito bite but not the same. Fleas can live for weeks or months on the surface of carpets and other soft furnishings.


The bites themselves usually do not swell, but if scratched, they can bleed. The bite site is usually one puncture point whereas the bites of other insects like mosquitoes and spiders produce two marks.

Hives and Welts

In addition to rashes, hives and welts can appear an hour after a flea bite. Hives are typically accompanied by itchiness and may even be painful. The itching and burning may increase with scratching. The hives appear in clusters of three or more. When the hives appear, it is important to avoid scratching or rubbing the area, as this can lead to an infection.

One symptom can lead to another. These symptoms can last for up to three weeks and require medical attention.

How to Treat Flea Bites On Humans

There are several natural and medical treatments for flea bites on humans. If the skin is infected with pus, antibiotics are necessary.

Natural Remedies for Flea Bites

However, it may not be as effective as some other remedies.

You can also try putting tea bags on the affected areas.
