Dealing with Bruises Next to Bug Bites: Causes, Treatment, Prevention

Dealing with Bruises Next to Bug Bites

It's every outdoor enthusiast's worst nightmare - you wake up after a day outside and notice an itchy, swollen bump on your skin. Upon closer inspection, you realize it's a bug bite. Even worse, it's surrounded by a dark bruise that stretches out around the bite. What could cause this? And more importantly, how do you treat it?

Bug bites often occur after being outside during the spring and summer months. Mosquitoes, ticks, bees, wasps, and more can strike at any time. Their bites usually result in red, itchy welts on the skin. However, bruises around a bite are less common and might mean something more serious is going on.

What Causes Bruising Around Bites?

There are a few reasons why bruises may accompany bug bites:

• The bug bite caused trauma to capillaries under the skin, allowing blood to leak into tissues and cause bruising.
• You scratched the bite vigorously, breaking capillaries yourself.
• The bug bite triggered an allergic reaction that caused inflammation and bruising.
• The bug bite introduced toxins that damaged tissue and blood vessels.

So in most cases, bruising is secondary damage caused by irritation and inflammation from the bug bite itself. However, some bugs like mosquitoes and ticks can directly inject toxins and anticoagulants into your blood while feeding. This makes bruising more likely.

Identifying Common Bug Bites with Bruises

Here are some of the most likely bug bite culprits that may leave behind bruises:

Mosquitoes

Mosquito bites often occur at night and are found in clusters or lines. Their saliva contains proteins that can cause delayed allergic reactions, leading to bruising around bites. Mosquitoes also inject anticoagulants when feeding to prevent blood from clotting.

Ticks

Ticks latch on to feed for extended periods of time. They also secrete toxins that can prevent blood from clotting properly. Pulling off an engorged tick can rupture blood vessels and cause bruising. Lyme disease from tick bites also comes with a bullseye rash that has a bruise-like appearance.

Bed bugs

Bed bug bites usually occur at night and are found in lines or clusters. They can provoke delayed allergic reactions and bruising. Their bites may also appear similar to mosquito bites.

Fleas

Flea bites cause tiny red bumps, often surrounded by bruises. The bruising is from blood leaking into the skin in response to irritants in flea saliva. Fleas often bite in groups and like to target ankles and legs.

Bees, wasps, and hornets

Being stung by one of these insects causes instant pain and swelling. Venom injected can cause localized tissue damage, allowing blood to seep into skin and create bruises. Those allergic may also experience extended bruising from inflammation.

Treating Bruises from Bug Bites

Here are some tips for treating bruises around bug bites:

• Clean the bite with soap and water to remove any remaining saliva or venom.
• Apply a cold compress to reduce swelling and bruising.
• Avoid scratching, which can make bruising worse.
• Try over-the-counter antihistamines, hydrocortisone cream, or anti-itch ointments.
• Take OTC pain medication like acetaminophen to relieve discomfort.
• See a doctor for severe reactions, especially if bruising spreads.

When to Seek Medical Care

Consult a medical professional if you experience:

• Bruising that spreads down an arm or leg in a line.
• Bruising accompanied by any swelling of the lips, face, or throat.
• A fever or flu-like illness after a tick bite.
• Pus, increasing warmth, or red lines around the bruise.
• Dizziness, weakness, or disorientation after a sting.

These can all indicate an infection or severe allergic reaction requiring medical intervention. Seek emergency care for any trouble breathing, swallowing, or fainting after a bite.

Preventing Bruises from Bug Bites

You can take these steps to avoid bug bites and subsequent bruising:

• Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus when outside.
• Wear long sleeves and pants when in wooded or grassy areas.
• Check carefully for ticks after being outdoors and remove any you find.
• Use netting over beds or cradles to prevent bed bug bites.
• Don't leave open food or drink containers outside that may attract insects.
• Keep yards free of standing water, stones, and debris where bugs congregate.
• Stay away from bee nests and hives, especially when mowing lawns.
• Treat pets routinely for fleas and ticks.

The Takeaway

Discovering a bruise around an insect bite can be concerning. However, in most cases it's simply collateral damage from the bite irritation itself. Using proper first aid and avoiding scratching can help the bruise heal quickly. Be on the lookout for any signs of infection or allergic reaction though, which would warrant seeing a doctor promptly. With some basic precautions, most bug bite bruises can be treated at home and fade away on their own.
