Do Wasps Bite or Sting? Facts About Wasp Stings vs Bites

Do Wasps Bite or Sting?

Wasps can be frightening insects, especially for people who have a fear of being stung. Their appearance and behavior can certainly seem aggressive at times. However, wasps do not actually bite. They exclusively sting as a form of defense.

Understanding the differences between wasp stings and bites can help you identify if a wasp is the culprit if you are injured by an insect. Learning more about wasp stinging habits and treating stings properly is also useful to minimize pain and avoid potential allergic reactions.

Appearance and Behavior of Wasps

Before diving into wasp stinging specifics, let's look at some general characteristics and habits of these buzzing insects:

Physical Features

There are over 30,000 identified species of wasps worldwide. Most have some common features including:

• Two pairs of wings (except for wingless female wasps)
• Long, slender bodies with a narrow "waist-like" area
• Legs with slender segments adapted for walking and hanging onto surfaces
• Visible antennae on the head

Colors vary widely between species from black, brown, and yellow to metallic blues, greens, reds, and oranges. Many wasps have contrasting patterns of bright colors. Compared to bees, wasps tend to have skinnier, less hairy bodies.

Nests

The majority of wasps are social and live in colonies, while some species are solitary. Social wasps build paper nests made from chewed up wood pulp. Nests can be found in trees, shrubs, under the eaves of buildings, underground, or hanging from branches and manmade structures.

Diet

Most wasps are carnivorous or omnivorous. They feed on other insects, spiders, caterpillars, honeydew from aphids, fruit, and scavenged meats. Only a small number of wasp species are herbivorous, feeding mainly on nectar and pollen.

Behavior

Wasps are generally more aggressive than bees, especially near their nests. They will vigorously defend the nest if they perceive a threat. However, unless bothered, wasps typically ignore and avoid humans.

Wasps Sting as a Form of Defense

Now that we've covered some background on wasps, let's get to the heart of the matter - stinging vs. biting. Here's a closer look:

Wasps Do Not Bite

Wasps do not have jaws or biting mouthparts capable of biting like mosquitoes, ticks, bed bugs, or spiders do. They solely have a stinger which evolved as a defensive weapon.

They Sting to Protect Themselves

Female wasps are the only ones capable of stinging since the stinger develops from the egg-laying ovipositor. Male wasps do not have stingers.

When threatened, wasps quickly jab their stinger into skin. This releases a dose of venom that immediately causes localized pain and inflammation.

Venom Discourages Predators

A wasp's venom contains toxic compounds including phospholipase and hyaluronidase that are meant to deter potential predators. The venom both inflicts pain and breaks down cell membranes at the sting site.

Stinging is a Last Resort

Stinging is an energy-intensive process for wasps, so they will not sting frivolously. Swatting at a wasp may trigger it to sting in self-defense. Otherwise, wasps generally only sting if their nest is disturbed or they are trapped against skin.

Signs of a Wasp Sting

If you are stung by a wasp, there are some clear symptoms to look for. These include:

Instant, Sharp Pain

You will immediately feel a very sharp, burning, pulsating pain at the sting site. This begins as soon as the stinger penetrates the skin.

A Small, Red Welt

A raised, red welt with a small puncture mark quickly forms where you are stung. This may be surrounded by redness and swelling.

Itching and Tenderness

As the venom spreads, itching, tenderness, and mild swelling often develop around the sting.

Possible Dizziness and Nausea

In some cases, people temporarily feel light-headed, dizzy, or nauseous soon after being stung due to the venom and pain.

A Lodged Stinger

Take a close look at the sting site. You may see the narrow, black stinger stuck in your skin. The stinger often stays behind after stinging.

These symptoms differentiate a wasp sting from a wasp bite. Bites do not leave behind stingers or cause instant burning pain.

Treating a Wasp Sting

Getting stung by a wasp is quite painful. Fortunately, there are many effective ways to treat stings at home to ease discomfort. Treatment strategies include:

Remove the Stinger

If you see a stinger stuck in the skin, use tweezers to gently grasp it as close to the skin as possible and pull straight out. Avoid squeezing the stinger, as this may inject more venom.

Wash the Area

Clean the sting and surrounding skin with soap and water to remove any remaining venom and decrease risk of infection.

Apply a Cold Compress

Wrap an ice pack or cold compress in a cloth and apply to the sting site for 10-20 minutes to reduce swelling, pain, and itching.

Elevate the Area

If stung on an arm or leg, keep the limb elevated above heart level to slow venom absorption and swelling.

Take Antihistamines

Over-the-counter antihistamines like Benadryl can help counteract allergic reactions and relieve itching.

Use Topical Creams

Creams containing lidocaine, hydrocortisone, or calamine can numb pain and soothe skin irritation from stings when applied topically.

Take Pain Relievers

For significant pain and swelling, take an over-the-counter pain medication like acetaminophen, ibuprofen, or naproxen.

Most wasp stings resolve within a few hours with proper first aid treatment at home. Seek medical care if you have a severe reaction.

Signs of an Allergic Reaction

While localized swelling, redness, and sting is normal, some people may experience a potentially serious systemic allergic reaction to wasp venom. Call 911 immediately if you have:

• Swelling spreading beyond the sting site
• Tightness in the chest or difficulty breathing
• Dizziness, confusion, or loss of consciousness
• Nausea, cramps, or vomiting
• Heart palpitations or racing pulse

These are signs of anaphylaxis and require epinephrine. People with known wasp venom allergies should carry injectable epinephrine like an EpiPen.

Home Remedies for Wasp Stings

In addition to first aid, these natural substances are traditionally used to provide relief when applied topically:

Honey

Antibacterial honey helps prevent infection and soothes irritation from wasp stings.

Apple Cider Vinegar

Dilute apple cider vinegar neutralizes venom proteins and alleviates stinging pain.

Baking Soda Paste

A paste of baking soda and water reduces swelling when applied to the sting site.

Aloe Vera Gel

Cooling aloe vera gel provides instant relief from pain and itching.

Paste of Meat Tenderizer

Meat tenderizers contain enzymes that help break down venom components to reduce effects.

Always clean the area first before applying a home remedy. Discontinue use if skin becomes more irritated.

Preventing Wasp Stings

You can reduce chances of being stung by taking some simple precautions:

• Avoid areas where you see wasp nests
• Prevent attracting wasps by cleaning up fallen, rotting fruit and food debris
• Wear light colors, avoid floral patterns, and forgo perfumes/colognes when outside
• Keep food and drinks covered outdoors
• Remain calm and still if a wasp approaches
• Have nests near your home professionally removed

Being observant of your surroundings and not inadvertently disturbing nests can go a long way in preventing painful wasp stings.

When to Seek Medical Care

In most cases, wasp stings can be treated effectively at home. Seek medical evaluation if:

• You have signs of a severe allergic reaction
• The sting site shows signs of infection like pus, redness, warm skin, or fever
• Sting pain and swelling persist beyond 48 hours
• You have multiple stings or are stung inside your mouth or throat

People with venom allergies should see a doctor after any wasp sting to assess if epinephrine or other treatment is needed. Contact a medical professional about testing and immunotherapy if you have experienced prior severe reactions to stings.

The Takeaway

Wasps only sting, they do not bite. While the stings are quite painful, there are many effective ways to treat them at home to speed relief. Watch for signs of allergic reactions which require immediate medical care. With proper first aid and avoidance measures, most wasp stings can be managed safely without serious complications.
