What is Flea Bite Hypersensitivity?

Flea bite hypersensitivity, also called flea allergy dermatitis (FAD) is the most common skin disease of dogs in the United States. According to studies, there are more than 15 antigens present in the saliva of a flea of which can cause an allergic response in your dog if she is sensitive to it. While flea control has improved, flea bite allergies and dermatitis are a common issue, with studies showing that up to 40% of dogs in a particular area will test positive for an allergy to flea bites.

Those dogs that are not allergic will usually not develop lesions from the bites, though they may bite or scratch at the flea as it bites them. Since dogs do not become desensitized to flea bites after an allergy develops, you will want to do your best to prevent them from being bitten by fleas. It does not appear that a particular breed or gender of dog is more likely to be allergic.

Flea bite hypersensitivity can be seen in any adult dog that is over one year of age, with many cases occurring between ages one and three.

Flea bite hypersensitivity occurs when your dog has a reaction to flea bites, experiencing itchiness and redness of the skin.

Symptoms of Flea Bite Hypersensitivity in Dogs

Symptoms of a flea bite allergy appear to be worse in the summer and fall, which are peak flea times. Should your dog have a flea allergy, you will see her bite at the base of her tail and scratch herself often and with intensity. In many cases, there will be a loss or thinning of hair above the base of the tail. Fleas themselves or their feces are often found on your dog, though if you bathe your dog often this may not be the case. In a severe case, your dog can itch all over her body, experience generalized hair loss and display red, inflamed skin. You may also observe hot spots when your dog is having a flea allergy.

  • Intense scratching
  • Hair loss
  • Presence of flea feces
  • Inflamed skin

Types

Some dogs are extremely hypersensitive to flea bites. In these dogs, they may be completely free of fleas as a result of self-grooming excessively. Because of the self-grooming, it may be difficult to find the presence of fleas or feces on your dog. A fine-toothed flea comb (32 teeth/inch) can be used to find fleas and their feces and you can also look closely at your dog’s bedding for eggs, larvae and feces.

Causes of Flea Bite Hypersensitivity in Dogs

Should your dog have flea bite hypersensitivity, she does not have to be infested with fleas to experience significant itchiness; only one flea bite can cause itchiness for a few days.

Diagnosis of Flea Bite Hypersensitivity in Dogs

Should you notice that your dog is scratching herself more than usual, you may consider a trip to the veterinarian so that she may be examined and receive some relief. Your veterinarian will ask you for information the symptoms you have observed and when you first noticed them. He will conduct a full physical examination of your dog; allergies to flea bites can be diagnosed through the observation of symptoms and in some cases the presence of fleas. Intradermal skin testing has been found to be effective in diagnosing a flea allergy, along with specialized blood tests (IgE blood tests).

Treatment of Flea Bite Hypersensitivity in Dogs

When treating flea bite hypersensitivity, your veterinarian will recommend both topical and oral medications that are able to be used for the control of fleas. An adulticide will eliminate the adult fleas, and an insect growth regulator (IGR) will help eliminate immature forms of the flea. This means that they will not reach adulthood and bite your dog in the future. Your veterinarian will take into consideration how severe your dog’s allergy is, how often she goes outside and willingness of your dog to let you treat her when making a recommendation on treatment. Allergy injections, also known as desensitization, may be helpful though are found to be successful in about half of those dogs with flea bite hypersensitivity. Corticosteroids can be used as they will greatly relieve the itching your dog is experiencing. Since there are major possible side effects, your veterinarian may not consider them the best option for your dog.

You will also want to treat your dog’s environment, to include the indoor and outdoor areas where your dog spends time, particularly the areas where she sleeps. While you may not see symptoms in other pets, you will want to treat them as well, so that they don’t bring fleas around the dog that is allergic.

Recovery of Flea Bite Hypersensitivity in Dogs

Monthly products are available (both oral and topical) that will be helpful in preventing fleas from impacting your dog. Should your dog develop a secondary bacterial skin infection as a result of scratching, your veterinarian may recommend antibiotics. You will then want to keep an eye on the infection to be sure that it is resolved. Once your dog has recovered, you will want to maintain a flea control program to avoid future infestation and allergic reaction.

Fleas are very small insects, about a quarter of an inch in length. They do not have wings, but their long hind legs are designed for jumping. They reproduce quickly and often live in fabrics and carpets.

Human and non-human animals are at risk of fleabites, which can be itchy and painful. Fleas can also carry human diseases. The most famous example of this was the plague.

Owning a pet increases the risk of a flea infestation, but it is not only pet-owners who are at risk. Fleas can enter the home on any fabric or fur. Once in the home, their quick breeding cycle means they can rapidly become a nuisance.

This article covers everything you need to know about fleabites, including how to identify and treat them. This MNT Knowledge Center article will also give advice on keeping your home and pets free of fleas.

Fast facts on fleabites

  • Fleas mainly feed on non-human animals but can bite and infect humans. They can be difficult to remove from the home and can survive for more than 100 days without a host.
  • Bites from fleas can trigger allergic reactions, but they will not often have a serious impact on a person’s health.
  • Fleabites will normally be very small with a central red spot, often appearing in groups of three or four.

  • The bites themselves will be very small with a central red spot.
  • They often appear in groups of three or four and sometimes appear in a line.
  • Fleabites will often form a small scab surrounded by a light red halo.

How do fleas bite humans?

Humans are often the secondary options when it comes to fleabites, as they do not make good hosts. They tend to become targets for hungry adult fleas who have not yet found the family pet or another, more suitable host.

If an adult or child happens to walk or crawl past an adult flea that has just emerged from its cocoon, they may be the first option for a meal.

Most people will not develop noticeable symptoms from a fleabite. In general, fleas do not carry diseases.

Small children and people who are allergic may have a bad reaction. This can include swelling and itching. The skin may become irritated and painful around the bite, and sometimes hives and a rash will appear. Scratching the bite can cause a secondary infection.

In most cases, fleas will be a nuisance and can indicate a household infestation that needs to be dealt with, but they will cause no serious symptoms.

Complications

There are two primary complications from fleabites. These are allergic reactions and secondary infections.

If a person is bitten and begins to show the following symptoms, they should seek medical attention immediately:

  • difficulty breathing
  • nausea
  • swelling of the lips or face

Flea Bites on Humans and Symptoms You Should Never Ignore

In most cases you don’t need to treat flea bites on humans, but there are some symptoms you should be aware of. It’s possible to develop flea bite symptoms because of allergic reactions, or get infections where the flea has bitten. Infection occurs when you scratch in and around the affected area. There is a lot of bacteria hiding under the fingernails, which goes directly into the open wound. So no scratching, no matter how much it itches.

As a rule, fleas bite people around the ankles or at least in the lower parts of the legs. Flea bites on humans can also be seen on the arms, after you have held your pet. The reason why the bugs attack the legs is that they live in carpets and whatever else is close to the floor. Fleas have absolutely no problems getting to you as they can easily jump over half a meter. See what their bites look like.

Do flea bites on humans itch?

The short answer is YES. Don’t worry though, if there are no apparent signs other than itching, they usually disappear by themselves. What makes flea bites itch isn’t the actual bite itself, it’s the flea saliva, which it injects into your body when it bites. It contains a substance which helps it to eat without being disrupted. If you or your pet has already been bitten by a flea once before, it’s possible to get an allergic reaction to the saliva.

How long do flea bites last?

Flea bites on humans most often occur in two to three groups or clusters of small red spots with redness around them. Slightly depending on how your body react to the bites (and how well you refrain from scratching the wounds), the reddish look last anywhere from a few hours up to several days. If you have very sensitive skin and a tendency to scarring, flea bites can lead to almost permanent scabs and marks. That is why it is very important to avoid scratching the bites. Also use a soothing ointment or scar cream to prevent permanent scar tissue.

How to treat flea bite symptoms

If you can refrain from scratching yourself after you’ve been bitten by a flea, you’re safe against further infections. These products all help to effectively relieve the itching, should you be unfortunate enough to be bitten:

Be careful not to scrub too hard, as you may risk making an even bigger hole in the wound. Ice or cold water soothes itching for a period and prevents swelling and inflammation. You should also clean the infected area with antiseptic soap, which prevents your body from being invaded by all sorts of nasty bacteria. Taking antihistamine might also help, but you should contact your doctor or pharmacist before you do that.

Treating flea bites on humans with vinegar

Vinegar is one of the best home remedies for flea bites. You can use apple cider vinegar, preferably raw and organic, with mother enzyme, for this remedy. Here are two ways to treat flea bites on humans with vinegar:

  • Insert a clean Q tip in the apple cider vinegar. Dab it gently on the bites. (Caution: do not use if you have blisters or open raw wounds in the bitten areas as the vinegar can sting).
  • You can add a cupful of vinegar to your bath water and soak in this bath to treat flea bites on the back, arms, torso and abdomen.

Vinegar is such a powerful remedy that you can also use to treat flea bites on dogs or cats. Add vinegar to the pet’s final rinse water while bathing. This will not only repel fleas, it will also make their coats shinier and glossier.

How to treat flea bites on babies

Babies have very delicate skin and the bites can lead to severe reactions. First of all, make sure that your baby has indeed been bitten by fleas. Sometimes, people tend to have bed bugs and may not even be aware of it. Read my article on flea bites vs bed bugs here. This will help you get an idea if you have fleas or bed bugs. Talk to your doctor if you are in doubt. Here are some home remedies for flea bites on babies:

  • Wash or ice the skin. If you choose ice, wrap the ice cubes up in a clean cloth and gently press it on the bitten areas. Ice for at least 10 minutes at a time and repeat 2-3 times a day. Pay attention to your baby’s comfort level and stop immediately if it causes discomfort.
  • Do not let your baby scratch the bites. You can use tiny mittens on your baby’s hands to prevent secondary skin infections.
  • Apply calamine lotion on the skin to ease skin irritation.
  • You can also use diaper rash ointment for the bites. This will prevent itchiness, redness and inflammation.
  • Aloe vera gel (use natural, organic products devoid of fragrance, parabens or dyes) can also help prevent itchiness.

Allergic reactions from flea bites on humans

Sometimes, flea bites can get very serious. Some people are more sensitive to flea bites than others. In the worst cases of flea bites on humans, people have reacted dangerously to the bites and have gone into anaphylactic shock. However, this occurs rarely and since you’re still reading, hopefully you aren’t hit that hard. Here are some other symptoms of allergic reactions from flea bites on humans. Contact your doctor if you experience any of this:

  • Difficulty breathing
  • Dizziness
  • Nausea
  • Swelling of the lips or tongue
  • Chest pain

Flea bite symptoms of infection

If you or anyone around you experiences any of the above symptoms, you should seek medical help as soon as possible. Ensure that you do not confuse an infected bite with an allergic reaction and cause unnecessary panic. The infections from flea bites on humans typically have the following symptoms:

  • Swollen glands
  • Redness
  • Pain in the area

The above symptoms should also be discussed with the doctor as soon as possible, but the situation usually isn’t as serious as the allergic reaction.

Get rid of flea bite marks faster

If you have followed the above advice to keep the area clean and make use of antihistamines shortly after you’ve been bitten, the itching will disappear after a few days. Flea bites on humans are likely to leave some marks, but don’t worry though, as they disappear on their own. They leave no scars and will be gone after a few weeks, but if you want to get rid of the marks faster, you can follow the advice below.

IMPORTANT! This treatment should only be used for flea bites on humans, when it no longer itches.

Use a mild exfoliant for the face and apply a little moisturizer on the bites. Repeat the procedure and be very careful, as it can irritate the bites. Also make sure to use some sunscreen every time you go outside. The new skin is very sensitive to light. It will probably be darker than the rest of the body when exposed to sunlight.

Fleas on humans can be as much a nuisance as fleas on animals, if you don’t know how to handle them. Learn how to get rid of fleas once and for all.
