Understanding Painful Wasp Stings and Preventing Anaphylaxis

Understanding Wasps and Their Painful Stings

Wasps are flying insects with long stingers that painfully sting as a defense mechanism or to paralyze prey. Their stings can be annoying at best or trigger dangerous allergic reactions at worst. This article explores different types of wasps, what their stings look like, how to treat them, and how to avoid getting stung.

Different Types of Stinging Wasps

There are many varieties of stinging wasps, including:

• Yellowjackets - black and yellow, build nests in holes
• Hornets - larger, brown or black bodies, build paper nests
• Paper wasps - long legs, build open comb nests
• Mud daubers - slender bodies, build mud nest tubes
• Cicada killers - large with reddish markings, nest in ground burrows
• Sand wasps - dig nests in sand or mud

Identifying Wasp Stings

Wasp stings cause an immediate burning pain. A typical sting will leave behind a puncture wound where the stinger entered and a white or red swollen bump surrounding it. The bump may itch and be irritating. Some key signs you've been stung by a wasp include:

• Sharp stabbing pain
• Swelling, redness, itching at wound site
• A visible stinger may be present
• Bruising or leaks fluid in severe reactions

Treating Mild Wasp Sting Reactions

For mild wasp stings that don't trigger an allergic reaction, there are several effective home treatments you can try to ease discomfort:

• Ice pack: Apply an ice pack wrapped in cloth to reduce swelling and pain.
• Baking soda paste: Make a paste of baking soda and water and apply to the sting area.
• Oral antihistamines: Take over-the-counter oral antihistamines like Benadryl to reduce body's reaction.
• Topical creams: Apply hydrocortisone cream, calamine lotion, or other OTC solutions.
• Heat application: Alternatively, apply a warm compress to the area to ease pain.

When to Seek Emergency Care for Wasp Stings

In some cases wasp stings can quickly trigger severe, life-threatening allergic reactions. Seek emergency care if you experience:

• Significant swelling away from the sting site
• Hives or rash spreading across body
• Chest tightness, difficulty breathing
• Dizziness, fainting, loss of consciousness
• Rapid heartbeat, low blood pressure
• Nausea, vomiting or diarrhea

Call 911 or seek hospital care immediately if you have a known wasp allergy and are stung, or if any signs of anaphylaxis occur. Untreated anaphylaxis can lead to death within minutes.

Preventing Wasp Stings

Some tips to avoid gets stung by wasps include:

• Eliminate exposed food that attracts them
• Stay away from areas wasps nest including holes, bushes, sheds
• Cover skin when outdoors, avoid bright colors/patterns
• Remain calm, avoid sudden movements near wasps
• Apply insect repellent if spending time in areas wasps frequent
• Hire a professional to safely remove problem nests

Common Questions About Wasp Stings

What's the difference between a bee sting and wasp sting?

Bees can only sting once since their barbed stinger gets caught and pulls away from their body when they try to fly off. Wasps have smooth stingers allowing them to sting repeatedly. Wasp stings also tend to be more painful with more swelling than bee stings.

Should I remove the stinger after a wasp sting?

You should flick away the stinger as soon as possible with your fingernail or using a straight edge. Only honey bees leave behind a stinger you need to remove. Trying to pinch or pull out a stinger that's not there may push more venom into the wound.

Why do some wasp stings get infected?

If a wasp stinger or venom enters deep enough it can introduce bacteria under your skin. Also scratching the sting area can expose it to germs leading to infection. Signs of infection include oozing pus, worsening redness, and fever.

What happens if you get stung by 100 wasps?

The high number of stings would release large amounts of venom that could be toxic and require emergency medical care. Without treatment severe stings can damage blood vessels, lead to falling blood pressure, impact other organs, and potentially cause death.

How long does a wasp sting last?

A normal single wasp sting may hurt for 2-3 days. The initial burning pain usually resolves in a few hours. Swelling, itching, and redness at the site can persist for up to a week. Multiple stings increase severity making symptoms last longer.

Preventing Anaphylaxis from Wasp Stings

People with allergies have higher risks of life-threatening anaphylactic reactions to wasp stings. A type of immunotherapy called venom immunotherapy (VIT) can help reduce risks.

What Is Venom Immunotherapy?

With VIT small amounts of wasp venom are regularly injected in order to make a person's immune system less sensitive to it. Gradually increasing venom exposure lets the body build protection rather than triggering suddendangerous allergic reactions.

Who Should Get Venom Immunotherapy?

Venom shots are recommended for people who have:

• Experienced a systemic reaction to a wasp sting
• A wasp sting allergy plus asthma
• Very elevated allergy antibody levels to wasp venom

Talk to your doctor if you have any severe reactions to determine if VIT is appropriate.

What to Expect With Venom Immunotherapy

During VIT, shots are given once or twice a week to start with dosage increases over time. The length of treatment can last for 3-5 years. Some redness and swelling at injection sites is common. Eventually maintenance injections are only needed every 4-6 weeks.

Over the long term VIT can provide substantial protection from future reactions in most patients. However it still does not guarantee you won't react again so those with allergies should still take precautions around wasps.

Staying Safe Around Wasps

Understanding wasp behaviors makes it easier to reduce risks:

• Diet consists of other insects, fruit, nuts, meats
• Nest in enclosed dark spaces like walls, holes in ground
• Most active late summer/early fall before new queens leave nest
• Won't sting without provocation as it may kill them
• Aggressively defend nests if threatened

Heeding warning signs like nest locations, numbers of flying wasps, time of year, etc. allows smart decisions about evading areas. Seeking treatment after stings is vital as well. Being aware and careful limits painful stings.
