Flea bitesHow Long Do Flea Bites Last? (Symptoms & Prevention)

How long do flea bites last? well, many people do not even realize that they have been bitten by a flea. But some people do face allergic reactions, intense itching, red inflammation and rashes.

Flea bites usually last for a couple of days. This totally depends upon the severity of the flea infestation and their skin sensitivity. Scratching flea bites might cause blisters. Open wounds should be covered as there are high chances of skin infection because fleas carry diseases.

What Is a Flea Bite?

Fleas are generally bloodsucking parasitic insects that live off humans, pets, and livestock. They usually range between 1-4 mm in length and are blackish-brown in color. They do not have wings but can jump to a height of a few meters. You would think that fleas would normally feed only on non-human hosts, such as cats and dogs, but make no mistake, humans are no exception to flea bites.

Even if you do not have pets of your own, your fleabites may be coming from your yard or another person’s animal. Most often fleas bite people on the legs, feet, and around the ankles as these are the most accessible parts of your body from the ground up. They could also spread to other parts of the body, especially to people with dense hair on their legs and chest.

When a flea bites, a red bump is usually formed as a result of an allergic reaction to flea saliva. Some people feel the bites immediately, others may experience increased irritation over time and the bites can remain sore and itchy for even up to a week. The lasting effects of flea bites can depend on the host and majorly on two factors, which are mentioned below:

Symptoms of flea bites on sensitive skin

Fleas are tiny and hard to see, but their bites are rather difficult to miss. Flea bites are usually small with a red spot in the middle and could often appear in groups of three or four. You may even notice a red halo around the bite center. The duration of the flea bite varies from person to person. Flea bites are normally harmless and if your skin isn’t the sensitive type, the bites usually vanish within a day or two. But not everyone is lucky enough to overcome flea bites that soon. For those with sensitive skin, and mostly in children, the allergic reaction could lead to the following symptoms:

  • Painful welts
  • Rashes
  • Skin inflammation around the bite
  • Intense itchiness

And in severe cases, could lead to:

  • Skin infections
  • Shortness of breath 
  • Swollen glands
  • Fever
  • Vomiting
  • Diarrhea,
  • Anxiety

These symptoms could last for up to two weeks, depending on the person. In some situations, the healing process could take longer if the sores get infectious.

What to do if you have flea bites?

Often it becomes hard to differentiate between a flea bite and similar-looking bugs or mosquitoes. It is therefore recommended that you ask a doctor to take a look at the bites and check for any signs of infections. Most of the time you can get rid of flea bites with home remedies and sometimes with over-the-counter anti-itch creams and antihistamine medications. If the sores of flea bites start to get painful and/or you experience symptoms such as fever, vomiting, or shortness of breath, you need to seek medical attention right away.

Doctors generally say that flea bites on humans can last up to one week, especially if the sores are not severely infected and if the person undergoes treatment for enhanced healing. Fleas may look innocent, but they are not. They can well be easy carriers of deadly bacteria that could cause dangerous diseases such as bubonic plague, tularemia, mycoplasma haemofelis, murine typhus, etc, thus prolonging/changing the treatment required and thus extending the recovery time.

Final Words

Flea bites usually go away without any treatment. To avoid getting bitten by fleas, you must take proper precautions to get rid of fleas themselves in the first place. Though not worrisome, flea bites can tend to get worse if you keep scratching the sores and may ultimately lead to infections. To ensure the redness or rashes go away quickly, please keep your hands off the bites.

If you feel that the sores are not healing for more than a week, it is always best to seek advice from a medical professional. Apart from shielding your skin from flea bites, it is just as important to protect your pets from fleas too. The key is to let the bites go away on their own, without hindering your health or taking up much of your time, and definitely without interrupting your day-to-day life.
