Why is There a Bruise Around My Bug Bite?

Why is There a Bruise Around My Bug Bite?

July 21, 2023

It's bad enough that bug bites make your skin itchy, swollen and red, but for some people, those welts can turn a dark color or even bruise. If that sounds like your experience, there's no need to worry. Insect bites with bruises are common, and they usually go away on their own in a few days. Why do some bug bites have bruises, and what type of insects cause them? MosquitoNix® can explain this phenomenon and how to prevent it from happening.

What Causes Bug Bite Bruises?

Before you think about bug bites causing bruises, you may want to understand what exactly a bruise is. This kind of injury results in broken blood vessels under the skin. That blood can pool and create a discoloration that feels tender when you touch it. When a bruise occurs along with a bug bite, it is because that bite injured the skin or created enough inflammation that some blood collects below the skin's surface.

Do All Insect Bites Leave Bruises?

Not every bug bite causes enough injury to make a bruise, but some insect bites or stings pack quite a punch. Fleas, bed bugs and gnats don't typically cause bruising or discoloration, but these insect bites can:

Ticks: Because they burrow under the skin, tick bites can look red or purple from the skin injury. You may not even notice when they bite you unless it gets itchy or swollen.

Spiders: While not actually insects, spiders can bite and cause pain, itchiness, and yes, bruising. Two spiders to watch out for are the brown recluse and the black widow. Their venomous bites can quickly turn red to purple and require immediate medical attention.

Hornets and Wasps: If you've ever been stung by a wasp or hornet, you know how bad their stings feel. They tend to bruise; after all, that stinger pierces the skin and breaks small blood vessels underneath.

Mosquitoes: Not every mosquito bite leaves a mark; for most people, this insect bite creates a red, itchy welt that goes away after a few days. Some people, however, are allergic to mosquito saliva, which leads to more inflammation and discoloration.

What Can Your Do To Help Bug Bite Bruises Heal?

When you first notice a bug bite, use an ice pack to numb any pain and control swelling. Over-the-counter medications, from anti-itch creams to antihistamines, can relieve some of the itching and irritation from insect bites. If you notice more significant symptoms, like difficulty breathing, nausea, confusion or wheezing, seek medical attention right away. You could be experiencing a significant allergic reaction to your insect bite that is much more severe than a bruise.

Of course, the best way to prevent any bug bite bruise is not to get bitten!
