Bed Bug Bite Symptoms On Humans

Did you know that bed bugs are now the most common pest you may encounter when travelling? The tiny creatures, who are approximately the same size as an apple seed, are probably more familiar to us than cockroaches. A number of people get rid of bed bugs every year, but in order to do so, they must first understand what causes these bites on humans. When most people think of bedbug bites, they think of clear, round red marks. These marks may be accompanied by intense itching. Bites from bedbugs are not like bites from other insects. In fact, the reactions to bedbug bites resemble those of a mosquito bite more than those of a typical bug bite. This is because bedbugs inject an anticoagulant that helps their body’s blood to flow freely. Bedbug saliva also contains anesthetics, which help the female avoid detection by her host as she inserts her straw-like mouthpiece into the host’s skin and sucks up blood. Bites from bed bugs usually occur while you are sleeping. Most people do not realize they have been bitten until bite marks appear. Bed bug bites are often mistaken for mosquito or flea bites or other types of insect bites. People react differently to bed bug bites, with some having no reaction at all, while others may have small, raised, itchy red bumps on the skin that can become swollen and tender. If a large area of skin is involved, itching may be intense. Symptoms can occur as soon as 15 minutes after being bitten and may continue to develop over a period of several days before completely healing.

Bed Bug Bite Symptoms On Humans


Bed bug bites are typically small and appear in a line or cluster. These bites can range from red to pink, but they’re usually painless and don’t itch like mosquito bites do.

In some cases, the swelling may be so mild that it’s not easily noticeable. In other cases, however, you may find that your skin has become discolored or swollen after being bitten by bed bugs (and this can happen as early as 6 hours after being bitten). If you notice swelling around the bite site within minutes or hours of being bitten by a bed bug—or if you experience any other side effects immediately following exposure—it’s probably due to an allergic reaction rather than an infection caused by bacteria or viruses associated with untreated wounds such as those caused by animal bites (ehrlichiosis), human immunodeficiency virus (HIV) infection, hepatitis B virus infection; Rocky Mountain spotted fever; syphilis; tularemia; West Nile virus disease caused by mosquito bites (mosquito-borne illnesses).


If you see signs of itching, it can be treated with over-the-counter antihistamines or prescription steroids. However, the itching may last for days or even weeks after the bite occurs.


Redness is a common symptom of bed bug bites. The redness may be localized to the bite area, or it may spread and become generalized. In some cases, redness may appear after an allergic reaction to bed bug saliva. This can happen if you have an allergy to an allergen that is found in the saliva of these insects and then are bitten by them. Bed bugs feed on blood, so they inject their victim with a digestive enzyme during feeding that allows them to break down proteins; this same enzyme can cause allergic reactions in some people who are bitten by these insects or otherwise exposed to it through contact with bed bugs (e.g., having their skin come into contact with bed bug fecal matter).

Painful bump

There is no guarantee that bed bug bites will be painful, but they are often very itchy or painful. Bed bugs often bite people while they are sleeping and therefore cause a lot of discomfort when you wake up with the bites. The bites themselves may look like little red bumps on your skin, but they can also be small blisters filled with pus.

Bed bug bites do not pose any health risks to humans; however, some people develop allergic reactions to them. Allergic reactions from bed bug bites include hives, itching, swelling of the face and arms/legs (angioedema), and sometimes a fever along with other symptoms like headaches or nausea.

Bed bug bites are not dangerous in any way; however, if you scratch at them constantly for an extended period of time then scabs may form which can lead to scarring over time if left untreated by a doctor who specializes in dermatology treatments such as laser resurfacing surgery designed specifically for removing scars caused by scratching too much over time because of having an allergic reaction after being bitten by one too many bed bugs living inside your home where they feed off human blood during their lifespan which only lasts roughly between one month up until one year depending upon how large each individual nest might be located above where you live within certain geographical regions because these creatures tend towards areas where there’s lots of moisture so that includes places like basements near drains pipes etcetera but since recent research shows there might actually be different species involved here instead (just assuming) then maybe we should keep looking into this further because if we do figure out what exactly causes those kinds

Skin rash or blisters

The most common symptom of a bed bug bite is a skin rash or blister. This is usually due to an allergic reaction to the bed bug’s saliva, which causes inflammation and irritation in your skin. You may also experience swelling around the bite area.

Symptoms will appear within seven days of being bitten, but sometimes it can take up to 12 days for them to show up. If you suspect that you have been bitten by a bed bug and are experiencing symptoms like those described above, seek medical attention from your local doctor immediately if:

  • You have a fever over 100 degrees F (37 degrees C) or feel very unwell
  • You experience pain when moving or touching the affected area

Allergic reaction

Allergic reactions to bed bug bites, either to the skin or to their saliva, are possible. The reaction can be life threatening and is called anaphylaxis. If you or someone in your household has any signs of an allergic reaction after a bite, seek medical attention immediately.

Knowing the symptoms of Bed Bug Bites will help you treat them more effectively.

  • Redness:

If you have a bed bug bite, the area will be red, similar to a mosquito or flea bite. It may appear slightly swollen and could even become inflamed with pus if the bite becomes infected.

  • Itching:

This is one of the most common symptoms of bed bug bites since itchy skin is something that most people can relate to. If you notice itching around your bedbug bite, it’s likely due to an allergic reaction (since they don’t inject any venom).

  • Painful bump:

A painful bump may form around each individual bedbug bite as they suck on your skin for blood; however, this is not always true as some people have no reaction whatsoever after a single infection. If this happens to you, it’s important that you seek medical attention right away!
