flea Bite Facts And Information

Fleas are tiny creatures, measuring only 2 to 4 millimeters in length, but they can cause a great deal of malaise for their host animals. There are more than 2,500 species of flea in the world and more than 300 species in the United States.

Fleas can survive in a variety of environments, including indoors and outdoors. They are most commonly found in areas where pets or wildlife reside.

What are flea bites, and what do they look like?

Flea bite

Fleas are tiny, wingless insects that can be found on both animals and humans. They bite to get blood and often leave behind red, itchy bumps on the skin.

Flea bites can pop up anywhere on the body but are most commonly found on the legs and feet since those are the body parts closest to the ground, where these parasites live.

While they typically occur around the ankles or legs, flea bites can also appear on any part of the body. Flea bite symptoms include redness, inflammation, and itching.

In most cases, flea bites are harmless and only cause minor discomfort. However, they can also spread serious diseases such as typhus, plague, and tapeworms.

Where can you generally find fleas?

Flea Bite facts and information

Insects like fleas also typically live in areas where there is an abundance of blood, such as on animals. Fleas will hop onto unsuspecting animals when they walk by these areas, and the fleas will then jump off of the animal to find their next meal.

However, it is worth remembering that fleas are most active when the weather is warm, and they can be found around trees, leaves, tall grass, and shrubs when they aren’t living on a host animal.

They tend to live in these areas because they provide plenty of places for the fleas to hide and lay eggs as well as a food source.

Fleas are often brought into the home through pets. Once inside, they may hide in carpet, furniture, bedding, and cracks in the floor. They can be highly difficult to get rid of and may require professional help.

Why do fleas bite humans?

Fleas are parasites that feed on blood. But, fleas typically prefer living on warm-blooded animals that have a lot of furs, in which they can hide and continue to feed on the host’s blood. They can bite humans in order to obtain blood if they don’t have any other host in their vicinity.

Further, female fleas need blood in order to lay eggs, and they will bite humans and other warm-blooded animals. After feeding on the host’s blood, the female flea will lay eggs on the animal or in the environment.

The baby fleas, or larvae, need to feed on flea dirt in order to grow and develop. Flea dirt is actually the poop left behind by adult fleas.

When a person gets bitten by a flea, it’s most usually because they’ve been standing or sitting near an area where there are many adult fleas. Otherwise, the chances are that fleas are going to restrict their infestations to your pet dog or cat!

Why do flea bites itch?

Fleas bite itch because the saliva of the flea contains an allergen. When this allergen enters your bloodstream, it causes histamine to be released. Histamine is the chemical that your body releases in response to a foreign substance, and it is responsible for most of the common symptoms associated with a flea bite.

Apart from the presence of this allergen, simply the act of a flea using its claws to dig into your skin and hold itself in place while it pierces your skin with a needle-like appendage can also cause a fair amount of irritation and itchiness on that spot!

What do flea bites look like on human beings?

Flea bites on human beings

Flea bites typically look like small, red, and itchy bumps that form at the spot where they’ve bitten your skin. They can be confused with the bites of a few other bugs, but they are typically smaller and more discolored.

Flea bites are usually not dangerous, but they can be itchy and cause a skin rash. They often show up as a straight line or in clusters of many bites. They usually occur on the lower legs, such as your feet, calves, and ankles, as I have already mentioned. However, they can also show up on other parts of your body.

What are the most common symptoms of flea bites?

Flea bites can cause a variety of symptoms, depending on the person. Some people may have an allergic reaction to flea saliva, which will cause a rash, intense itching, and hives. Other people may contract diseases from the fleas, such as typhus or bubonic plague.

Fleas can also carry tapeworms, so it is important to seek medical attention if you are bitten by a flea and experience any unusual symptoms.

How to treat flea bites?

Flea bites typically don’t need treatment as they will usually go away on their own. However, if you experience an excessive amount of discomfort or if the bites are becoming infected, you can take some steps to treat them.

Some simple remedies include using a cold compress, applying calamine lotion, or taking an anti-histamine.

If your symptoms seem to worsen, it would be best to consult your doctor on what steps you need to take to alleviate these symptoms. However, this is a rare scenario, and the irritation and itchiness from flea bites will generally reduce in a few hours by themselves.

What do you need to do to prevent getting bitten by fleas?

Treat your pet for a flea infestation

Well, the fact is that if you’re getting bitten by fleas, your pet animal probably has a flea infestation walking around in its fur coat. Therefore, to prevent getting bitten by fleas, the best way to proceed is to control the flea infestation on your pet. A few ways to do this are –

  • Bathe your pet with a quality ectoparasiticidal shampoo that kills fleas in all stages of their life cycle.
  • Regularly comb your pet’s fur using a fine flea comb. Once you manage to trap the fleas in the comb, you should soak the comb itself in a bowl of heated soap solution.
  • You should also clean your pet’s bedding material regularly by having it laundered and vacuumed to get rid of any stray fleas nesting in it.

Flea bites vs. bed bug bites – What is the difference?

The difference between the bites of these two insects is the pattern they appear on your skin. Typically, you will find that bed bugs will leave bite marks in a line on your skin.

Further, bed bug bites will usually appear on your skin when you’ve spent a large amount of time in your bed, whereas fleas will bite you regardless of your proximity to your bed!

How long do flea bites irritate your skin?

Flea bites can be itchy and irritating, especially if you scratch them. These bites can last anywhere from a few days to a couple of weeks if you have a severe allergic reaction.

If you scratch the spots where these pests have bitten you, you could end up infecting the bites. Once they are infected, it will take a lot of time and proper medication for them to heal entirely. The symptoms of the allergic reaction may take many days or even weeks to go away.

How can you stop flea bites from itching?

Aloe vera gel

There are numerous over-the-counter and home remedies that can help alleviate the irritation caused by flea bites. The vast majority of people may safely use homemade cures. Before attempting any of the following remedies for flea bites, be sure to consult with your doctor first.

Using over-the-counter medication

There are a few popular ways to stop flea bites from itching. One option is anti-histamines, which are chemicals that block the effects of histamine. They can be taken orally or topically.

Corticosteroids, such as hydrocortisone, are another option and work by reducing inflammation. Finally, calamine lotion is a topical ointment that helps soothe the skin and has anti-histamine properties.

Icing the flea bite

When it comes to flea bites, one of the most common questions is how to stop the itching without using any medication. One simple way is to apply ice to the bite.

Ice can gradually reduce the amount of blood that flows to an area, reducing inflammation, pain, swelling, and itchiness.

Aloe vera gel or honey

Aloe vera gel is rich in salicylic acid. This acid is the main functional chemical that reduces the itchiness and malaise of flea bites. Therefore, smearing or massaging some aloe vera gel onto the bite is another remedy that you can try.

In addition, honey is an effective remedy against minor inflammation, and it can also relieve itching and pain.

Ultimately, you must remember to avoid scratching the bite spot violently. If you happen to break the skin at that spot, exposure to an unsanitary environment can cause severe infection, which will require medical attention.


Flea bites are not the best thing in the world, obviously. But, knowing about them can help save you plenty of trouble.

What you should remember is that flea bites don’t generally need any specific attention apart from a plan of action to get rid of flea infestations in your house. Having said that, there are plenty of things you can do to deal with these bites!
