Identifying Yellow Fly Bites and Other Common Bug Bites

Identifying Yellow Fly Bites

As the weather warms up and you spend more time outdoors, you may notice mysterious bites or stings appearing on your skin. While many bug bites are harmless, some can lead to painful reactions or spread serious diseases. So it's important to identify the culprit behind any new marks on your body.

One common outdoor pest in the southern United States is the yellow fly. Keep reading to learn how to recognize yellow fly bites, treat their symptoms, and prevent future bites.

What Are Yellow Flies?

Yellow flies are a group of biting flies that are active during the day in warm weather. There are over 1,000 species of yellow flies, but some of the most common include:

• Deer flies
• Horse flies
• Yellow jacket flies

These flies can be up to 1 inch long and are often hairy, with brightly patterned wings. They are attracted to movement and carbon dioxide from breath. Yellow flies have sharp mouthparts they use to pierce skin and extract blood from mammals, birds, and reptiles.

Where Are Yellow Flies Found?

You'll find yellow flies buzzing around areas like:

• Fields
• Forests
• Parks
• Beaches
• Wetlands

They thrive in warmer environments and are most active on hot, humid days. Yellow flies are common across the southern United States, from Texas to Florida. They can also be found in some Midwestern and Western states.

What Do Yellow Fly Bites Look Like?

When a yellow fly bites you, it will pierce your skin with its sharp mouthparts. As it extracts blood, you may feel a sharp, stabbing pain. The fly's saliva also contains proteins that can trigger allergic reactions for some people.

A fresh yellow fly bite will appear as a small red dot, sometimes surrounded by swelling and irritation. The bitten area may itch intensely. Over the next few days, the bite can turn into a hard, raised welt.

Yellow fly bites usually occur on exposed skin, especially:

• Arms
• Legs
• Feet
• Shoulders

But they may bite other areas as well. Multiple bites in one area are also common.

Treating Yellow Fly Bites

Yellow fly bites are painful and itchy, but typically clear up on their own within a week. Here are some tips for managing bite symptoms:

• Wash the bite with soap and water to clean it.
• Apply an ice pack to reduce swelling and itching.
• Take an antihistamine containing diphenhydramine (Benadryl) to relieve itching.
• Use hydrocortisone cream on the bite to decrease inflammation.
• Avoid scratching the bite, which can worsen irritation and increase risk of infection.
• See your doctor if bite symptoms do not improve within a few days.

Preventing Yellow Fly Bites

You can take steps to avoid those painful yellow fly bites when spending time outdoors:

• Wear light-colored clothing, which is less attractive to flies.
• Cover up exposed skin with long sleeves and pants.
• Use an EPA-approved insect repellent containing DEET, picaridin, or oil of lemon eucalyptus.
• Avoid perfumed soaps, shampoos, and hair products.
• Stay away from stagnant water sources where flies congregate.
• Keep food and drink covered and dispose of waste promptly.
• Install fly traps around your patio or outdoor gathering areas.

When to Seek Medical Care

In most cases, yellow fly bites can be treated at home without medical intervention. But you should contact your doctor if you experience:

• Signs of a severe allergic reaction like trouble breathing, throat swelling, or fainting
• Fever, headaches, muscle aches, or swollen lymph nodes
• Pus, increasing redness, or streaks around the bite
• Multiple painful bites

Rarely, bites may transmit diseases like tularemia. Seek prompt medical care if bite symptoms seem severe or worrisome.

Identifying Other Common Bug Bites

In addition to yellow flies, there are many other bugs that can bite during the warmer months. Here's how to identify some common bug bites:

Mosquito Bites

Mosquitoes use their long, needle-like mouthparts to pierce skin and draw blood. Their bites often appear as small, red, itchy bumps on exposed skin. Mosquito bites may swell significantly on some people. Scratching them can lead to infection.

Tick Bites

Tick bites often go unnoticed until after the tick detaches from the skin. The bite appears as a small red bump or mild rash. Tick bites can transmit diseases like Lyme disease and Rocky Mountain spotted fever when the tick has been attached for over 36 hours.

Flea Bites

Flea bites usually occur around the ankles and legs in small clusters. They are tiny, red, and very itchy. Scratching flea bites can cause infected sores. Treat pets promptly with flea control products if you develop flea bites.

Bed Bug Bites

Bed bug bites appear as raised, red welts in zigzag lines or clusters. They're often found on the face, neck, arms, and torso. Bed bug bites are very itchy and may cause a rash. They often indicate an infestation inside mattresses, furniture, and floors.

Spider Bites

Most spider bites are harmless, causing temporary irritation and itching. But the bites of black widows and brown recluse spiders can result in pain, swelling, blisters, fever, and muscle aches. Seek medical care immediately if you suspect a bite from one of these venomous spiders.

Chigger Bites

Chiggers are mite larvae in grass and vegetation that bite humans. The bites appear as intensely itchy, red welts concentrated around the ankles, legs, or waistband. Chigger bites usually resolve after 7-10 days. Treat with OTC anti-itch creams.

Fire Ant Bites

Fire ants clamp down with their jaws and sting from their abdomen, injecting a venom. This results in a painful, burning welt that forms a white pustule on the top. Fire ant stings are very itchy and can cause swelling and allergic reactions in some people.

When to See a Doctor for Bug Bites

While most bug bites can be managed at home, contact your doctor if you experience:

• Signs of infection like pus, red streaks, swelling, fever, or chills
• Facial swelling or trouble breathing after a bite or sting
• Multiple painful bites or stings
• Continued spread of rash or redness around the bite
• No improvement in symptoms after a few days
• Known allergy to insect stings

Seeking prompt medical treatment is especially important if bites could have come from venomous insects like spiders, bees, or scorpions. Be sure to give your doctor details about the bite and your symptoms.

With proper identification and care, most bug bites can be treated at home. But recurrent reactions or concerning symptoms should be evaluated by a medical professional. Taking steps to prevent bug bites and stings is always the safest approach during the summer months.
