Mosquito bite like bump: What Causes Them and How to Treat Them

What Causes Them and How to Treat Them

Mosquito bites are itchy bumps that occur after female mosquitoes puncture your skin to feed on your blood, which helps them produce eggs. When they feed, they inject saliva into your skin. Proteins in the saliva cause a mild immunologic reaction, which is what leads to the bump and itchiness.

These bumps are usually puffy, red or pink, and appear a few minutes after you get bitten. However, some people may have a more severe reaction, which can lead to fluid-filled blisters instead of puffy bumps.

Read on to learn more about why this happens and how to treat a mosquito bite that turns into a blister.

Some people have stronger reactions than others to mosquito bites. This reaction can include a lot of swelling, beyond the small bump most people get. When the area becomes swollen, fluid can come up under the top layers of skin and form a blister.

This reaction is natural. While everyone has a mild reaction to mosquito bites, some people are more likely to have quicker reactions than others. There’s nothing you can do or not do to prevent a blister from forming when you get a mosquito bite.

However, children, people with immune system disorders, and people who are bitten by a type of mosquito they haven’t previously been exposed to may have more serious reactions.

In the case of children, this may be because they aren’t desensitized to a mosquito’s saliva like most adults are.

Mosquito bites, including ones that blister, will usually go away by themselves in a few days to a week. Until they do, you can relieve some of your symptoms.

Protecting the mosquito bite blister is important. When the blister first forms, gently clean it with soap and water, then cover it with a bandage and petroleum jelly, like Vaseline. Don’t break the blister.

If the blister is itchy, you can apply lotion before covering it. If the lotion doesn’t work, you can take an oral antihistamine.

See a doctor if you have signs of:

  • Infection. Pus, sores, fever, and redness that spreads from the bite site and doesn’t go away can be symptoms of infection, as well as swelling in your lymph nodes.
  • Mosquito-borne diseases. For example, West Nile virus symptoms include headache, joint pain, fever, fatigue, and a general feeling of being unwell.
  • Allergic reaction. This may be a medical emergency.

Medical emergency

It’s possible to have a serious allergic reaction after being bitten by a mosquito. Go to the nearest emergency room if you have a blister and the following symptoms:

  • hives
  • trouble breathing
  • swelling in your throat or lips

Common symptoms of a mosquito bite include:

  • itchiness
  • puffy red or pink bump, or multiple bumps, that appear a few minutes after the bite
  • dark spot once it heals

Some people may have more serious reactions to mosquito bites. These can include:

  • a lot of swelling and redness
  • low-grade fever
  • swollen lymph nodes
  • hives
  • swelling in areas away from bite, like your joints, face, or tongue
  • dizziness
  • trouble breathing (a sign of anaphylaxis that needs emergency medical attention)

Most bug bites will just create a small bump and itch for a few days. However, there are other types of bug bites that can blister, including:

  • fire ants
  • ticks
  • brown recluse spider

See a doctor immediately if you think you might have been bitten by a brown recluse spider. These bites can cause a serious reaction.

It might be impossible to totally avoid mosquito bites, but there are some ways you can reduce your risk for getting bitten. Follow these tips:

  • Wear long pants and long sleeves while outside.
  • Avoid outdoor activities between dusk and dawn, when mosquitoes are most active.
  • Use insect repellent with DEET, icaridin, or oil of lemon eucalyptus. Be sure to follow the product’s directions. Be careful not to get them in your eyes or any cuts.
  • Wear a hat that protects your neck and ears.
  • Use mosquito netting if you’re sleeping outdoors.
  • Eliminate standing water near your home, such as in gutters or wading pools. Female mosquitoes lay their eggs in standing water.
  • Keep the doors and windows of your home closed, and make sure screens don’t have any holes.
  • Avoid using heavy perfumes, which may attract mosquitoes.

Most mosquito bites lead to a puffy, itchy bump. However, in some cases, they can turn into blisters.

While this is a more robust reaction, it’s not a sign of a problem unless you have symptoms of an infection or allergic reaction, such as fever or trouble breathing.

See a doctor if you have any symptoms or signs of an allergic reaction or infection.

What you need to know about Skeeter Syndrome

It’s common for a mosquito bite to cause a slight reaction on your skin. This reaction can worsen over the next 24 hours, but it usually gets better from then on, often clearing up within a week.  

More rarely, though, you may experience a more severe reaction called skeeter syndrome. Here’s what you need to know about this condition. 

Skeeter syndrome is diagnosed when you have a strong reaction to a mosquito bite. You may see a large area of swelling, soreness, redness, and itching or pain at the location of the bite. Such a reaction can develop within hours of the bite, and it may last for weeks. 

You may notice some redness and puffiness within a few minutes of the bite, followed by a red-brown bump showing up over the next two days. The bump is usually hard and itchy. Sometimes, you may get small blisters or small dark spots that look like an injury. 

You need to be in contact with a mosquito for at least six seconds for this type of reaction to take place.  

Skeeter syndrome is caused by the body’s reaction to polypeptides found in a female mosquito’s saliva. Polypeptides are chains of molecules called amino acids.

A female mosquito needs to feed on blood to produce eggs. Mosquitos use a mouthpart called a proboscis to pierce your skin and suck up the blood. While they suck blood, they also inject a small amount of saliva into your body because the saliva contains a substance that stops the blood from clotting. Male mosquitos don’t bite humans. 

Skeeter syndrome is rare, but some people are more likely to get it than others.

  • Babies and children, as they have lower immunity. 
  • Adults bitten by a species of mosquito they’ve not come in contact with before. Polypeptides can differ from one mosquito species to the next. A person can have Skeeter syndrome from getting bitten by one species but have no reaction to a bite from another species.
  • People who have an immune system disorder. That’s the system that protects your body from infections. 

If you’ve had several mosquito bites, you become less sensitive to the saliva, so severe types of reactions like Skeeter syndrome are not very common.  

A large area of swelling, soreness, and redness with pain or itchiness is common in a severe reaction. In addition, you may become feverish. Skeeter syndrome symptoms can also include hives, a type of skin rash. Your lymph nodes, parts of your immune system, may also get swollen. 

Your primary care physician or doctor can assess whether you have skeeter syndrome by looking at the affected area on your skin. There is no blood test to check for the syndrome, so your doctor will usually arrive at their diagnosis after finding out if a mosquito has bitten you.

Your doctor will want to know your symptoms and how long you’ve been having them before they suggest a treatment plan. They will also check your medical history and ask about medicines, vitamins, supplements, and any other form of treatments you’re taking currently.

Skeeter syndrome treatment usually involves oral antihistamines and topical steroid creams.

Oral antihistamines are a class of drugs used to treat the symptoms of allergies. They are taken through the mouth. Topical steroid creams are creams, lotions, or ointments containing steroids that help fight inflammation in the body. These are to be applied to your skin near the site of the infection. Sometimes, your doctor may ask you to take oral steroids.

Avoid scratching your bites as that can lead to an infection. 

There are several different things you can do to help prevent mosquito bites: 

Use insect repellants. Use Environmental Protection Agency (EPA)-registered insect repellants. As long as you follow the product label instructions, they should be safe and work well for pregnant and breastfeeding women. You will always want to follow the instructions, though, to ensure safe application.

An EPA registration can tell you that the repellent has had its effectiveness confirmed. It can be unclear how effective natural insect repellants or non-registered ones are.

Avoid using insect repellants containing oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD) on children under 3 years of age. Avoid applying insect repellent on your child’s hands, mouth, and eyes. You will also want to avoid applying it to any cuts or open infections that your child has.

Cover your body. Use long-sleeved tops and long pants to protect your body from bites. Thicker clothing can be harder for mosquitos to bite through.

Treat your wearables. Treat your clothes and even things like boots, mosquito nets, or the tents you’re sleeping in with a 0.5% solution of an insecticide called Permethrin. Permethrin can kill mosquitos on contact. You can also buy clothes that have been treated with Permethrin for when you’re traveling.

Avoid applying Permethrin directly on your skin.

Use mosquito nets and screen guards. Use mosquito nets in hotel rooms with no air conditioning or on occasions when you’re sleeping outside. Use protective screen guards for your doors and windows. Follow up with indoor pesticides if you’ve had mosquitos or use the services of a professional pest control professional.

Use air conditioning as much as possible when you’re indoors.

Manage areas that hold water. You may have water features or areas that hold water both inside and outside your home, like buckets, pools, flowerpots, birdbaths, or trash containers. Empty these containers once a week and clean and scrub them from the inside out.

Fill tree holes so they don’t get clogged with water. Also, repair cracks and holes in your septic tank if you have one. Cover open vents and plumbing pipes.

Clear out areas that are damp and humid like the inside of your closets, the space under your sinks, or your laundry room.

Skeeter syndrome is rare. Call your doctor if you suspect that you have skeeter syndrome or if your mosquito bite symptoms are getting worse. Follow best practices both indoors and outdoors to prevent mosquito bites and safeguard your health.
