When an insect bites, it releases some saliva and some other substances into the body.
When these substances get to your bloodstream, they cause the skin around the area to get swollen and blistered.
Most people only get bumps that appear pink or red after the occurrence.
Some people, however, may develop severe reactions to this, causing their skin to get filled with fluid and become blistered.
This article contains all you should know about bug bite blisters, including possible treatments for them.
What type of insect bite leaves a blister?
Bites from insects cause a lot of itching and redness on the affected area.
However, it is not every insect that can cause a blister. Some insects that can cause you to have a blister include:
Almost everyone reacts to mosquito bites, and that reaction can range from mild to severe. Severe cases of reactions to mosquito bites can lead to fluid-filled scars and blisters.
When female mosquitoes bite into your flesh and suck your blood, they feed and inject saliva into your body.
This saliva contains some proteins that cause mild immunologic reactions, which leads to bumps, itchiness, and eventually blisters in infected persons.
Wasp and hornets are insects that leave a blister when they bite you.
A hornet sting causes a sharp pain at first, which later develops into swollen, red marks that might remain for weeks. In severe conditions, anaphylaxis might occur.
Bee stings are like hornet stings. The sting often causes redness, pains, and swollen skin that lasts for days.
The sting and blisters might come with a series of allergic reactions in people who are allergic to them. It could take weeks to heal.
Tick bites feel different because they do not cause you pain immediately after you get stung. It takes a while before you realize you’ve been bitten.
Symptoms accompanying a tick bite include a small, red lump on the skin, blistering, itchiness, and bruising.
Spiders are another group of insects that cause blisters when they bite you. Each bite from a spider makes a hole in your skin, and venoms from the insect get into the hole.
This venom, when mixed with your blood, can react adversely in your body system, causing visible reactions like blistering and redness of the skin.
Other insects that might cause blistering, alongside a range of unpleasant symptoms when they bite you, are:
- Gnat bites
- Bedbug bites
- Flea bites
The blister beetle is a bug that causes a raised patch of skin after a bite. The patch of skin can be referred to as a welt, water blister, or a pocket of fluid or pus.
This condition develops 24 to 48 hours after one comes into contact with the beetle.
The water blisters from the beetle bite are temporary and would heal in some days. The condition is not dangerous but can spread to other parts of the body it comes into contact with.
The short answer to this is no. You should not pop blisters from a bug bite because they can lead to infections.
Blisters usually heal on their own within a few days, unless you decide to pop them. Bursting them will expose the skin beneath, delaying the healing process and exposing the affected area to infections.
It’s most advisable that you use an adhesive bandage or gauze to protect your surface from rupturing.
Although not all spider bites result in blisters, some spider bites, such as the brown recluse spider, can cause your skin to get blistered.
These categories of spiders often cause reddening of the skin around the affected area, constant itching, and pains that develop 3-4 days after the bite.
The sore may take months or less to heal, depending on the care you give to the wound. Pilling the surface, itching, or bursting the blister are actions that can make the blister take longer to heal.
Infection can cause a single blister or a cluster of blisters depending on the severity of the condition.
Most blisters that form from a bug bite are filled with clear fluid.
The blister mostly gets filled with pus when the blister becomes infected. The symptoms most common to bug bites include irritation, redness, swollen skin, itchiness, and blisters.
When the fluid present in your blisters goes from a clear fluid to a pus-filled liquid, then that is a sign that you have an infection. Infected blisters should be treated immediately to avoid further complications.
How Long Do Bug Bite Blisters Last?
Most blisters from a big bite are temporary. Therefore, the symptoms of a bug bite blister should heal within a week or two in people with mild conditions.
Sometimes, however, they can last for a little longer than that. This could be when they get infected or the affected individual is allergic to the insect bite.
When the latter happens, the situation worsens and gets accompanied by a medical condition called anaphylaxis.
Illnesses spread throughout the body, and the healing process extends beyond the expected time.
Such conditions will take longer than the expected one to two weeks to heal. They may take months to heal instead.
What Does A Bug Bite Blister Look Like?
A blister bug bite looks like a raised, red patch of skin filled with fluid or pus.
The fluid is a clear liquid that might pose if it bursts or gets popped. The visible signs and symptoms develop particularly in areas exposed to the bug bite.
Bug bite blisters start with pain, itching, burning, and redness, after which it progresses to swelling and formation of blisters. These symptoms will typically develop 24 to 48 hours after the bug bite.
Insect Bite Blister Treatment
Treating your bug blisters should come easy if you follow the proper steps needed. Bug blisters are expected to heal on their own in a couple of days.
However, there are still basic things you can do to hasten up the healing process and help yourself get better quickly. Some of them include:
1. Treating regularly
You can take care of your blisters regularly by cleaning with warm, soapy water every day.
Ensure you do this carefully in order not to pop the blisters. After cleaning the blisters gently, apply some ointment, topical steroids, or antibiotics to hasten the healing process.
This kind of care would help you avoid possible secondary infections that could come with bug blisters.
It would ease the redness, swelling, and pain. Besides this, try not to scratch the surface of your blisters.
If the pain gets unbearable, see your physician for medications.
2. Cover the surface of the blisters
This method of treatment can be effective as it helps keep your blisters safe from external factors.
Keeping it covered will reduce the likelihood of it getting punctured or popped. Ultimately, this would help reduce the risk of it getting infected.
You can do this by covering with a bandage, gauze, or clean piece of clothing. Keep the surface clean every time and do not wrap the blister too tightly.
3. Apply a cold compress
Another easy way to reduce pains from your blisters and also help them heal faster is by applying a cold compress.
Applying a cold compress to your lesion every day can help ease the swelling and the pain.
Place a flannel, or cloth soaked in cold water over the affected area, repeat two to three times daily.
Also, ensure that you do not apply too much pressure on the blisters.
Although staying indoors doesn’t guarantee that you would be safe from bug bites, taking part in regular outdoor activities can make you more susceptible to insect bites.
One effective method that you can adapt to shield yourself from the harmful effects of insect bites is to use insect repellent and keep your skin covered when you are outdoors.
Bug bite blisters are not dangerous and rarely cause scarring. However, if treated carelessly, they could worsen and develop into complications.
Protect yourself by adopting preventive measures and treatment.
Do not forget to pay a visit to your physician if the blisters get infected or take too long to heal.
