Do Bumble Bees Have Stingers? The Quick and Surprising Answer

Bumble bees are fascinating and important insects that play a crucial role as pollinators in our ecosystems.

They are large and hairy, often sporting vibrant colors like black and yellow or black and white. But one question that commonly arises is whether or not bumble bees have stingers.

Do Bumble Bees Have Stingers

Yes, bumble bees do possess stingers.

However, not all bumble bees sting. Female bumble bees, which include both queens and workers, can sting when they feel threatened or when protecting their nests.

Unlike honey bees, bumble bee stingers do not have barbs, allowing them to sting multiple times without harming themselves.

Interestingly, male bumble bees do not have stingers at all, which renders them incapable of causing any harm through stinging.

Bumble Bee Basics

Types of Bees

Bumble bees are one of many types of bees that make up the insect group known as pollinators.

They are typically larger and fuzzier than honey bees, with three distinct types within a colony: queens, workers, and males.

  • Queens: Female bees that reproduce and establish new colonies
  • Workers: Female bees that gather nectar and pollen, and defend the colony
  • Males: Male bees that mate with queens and have no further duties

Habitat and Ecosystem

Bumble bees can be found in various habitats, often near native plants that provide nectar and pollen. They play a crucial role in the ecosystem by:

  • Pollinating wildflowers, trees, and shrubs
  • Providing food for birds, bats, and other insects through their pollination efforts

Bumble Bee Pollination

Bumble bees are efficient pollinators because they can gather pollen from numerous plant species.

They use a unique method called “buzz pollination” to release pollen from flowers:

  • The bee rapidly vibrates its wing muscles, creating vibrations to release pollen from flowers
  • This allows better access to the flower’s nectar and increases the pollination process
Bumble Bee

Endangered Species and Conservation

Climate change and habitat loss have led to a decline in bumble bee populations:

  • Some species are listed as endangered
  • Conservation efforts focus on preserving native plants and habitats

To support bumble bee conservation, consider:

  • Planting native flowers and plants that provide food sources for bees
  • Avoiding pesticides harmful to bees in gardens and landscapes
Habitat loss Climate change
Destruction of native plants Changing temperature and precipitation patterns
Urbanization Extreme weather events affecting food sources and nesting sites

By understanding these basic concepts about bumble bees, we can better appreciate their vital role as pollinators and work towards protecting their habitat and population for future generations.

Stinging Behavior and Mechanism

Do Bumble Bees Have Stingers?

Yes, bumble bees have stingers and can sting. However, they are generally docile and not aggressive unless their nest is disturbed or they feel threatened1.

Stinger Structure

  • Bumble bee stingers are smooth and have a slight curve.
  • Unlike honey bees, bumble bees do not possess barbs in their stingers2.
  • Due to the absence of barbs, bumble bees can sting multiple times.

Stinging Process

  1. Bumble bee identifies the threat.
  2. The bee positions itself to sting.
  3. The stinger penetrates the skin, and venom is injected.

Note: Bumble bee venom may cause pain, swelling, and itching at the sting site3.

Yellow Faced Bumble Bee

Male and Female Bumble Bees

  • Only female bumble bees have stingers4.
  • Male bumble bees, on the other hand, do not possess stingers.
  • The sting of a female bumble bee can be more painful than that of a male carpenter bee5.

Comparison Table

Feature Male Bumble Bee Female Bumble Bee
Stinger No Yes
Sting pain level N/A Moderate
Aggressiveness Low Low (unless provoked)

Reactions and Risks

Symptoms of a Bumble Bee Sting

  • Pain: A bumble bee sting is usually painful and occurs immediately after the sting.
  • Swelling: The area around the sting often becomes red and swollen within a short period.
  • Itchiness: The sting site may become itchy after the initial pain and swelling.

Allergic Reactions

Some individuals may experience an allergic reaction to a bumble bee sting, which can include symptoms like:

  • Difficulty breathing
  • Rapid heartbeat
  • Hives or rash
  • Nausea or vomiting

It’s essential to consult a physician if any of these symptoms arise as they can be life-threatening and require immediate medical attention.

First Aid For Bumble Bee Stings

Bumble bee stings can be painful, but they’re usually harmless for individuals without an allergy. If you’ve been stung by a bumble bee, here are some practical steps to alleviate the discomfort:

  1. Stay Calm: Panicking can increase your heart rate, which may spread the venom faster. Take deep breaths and try to remain calm.
  2. Remove the Stinger (if present): Unlike honeybees, bumble bees can sting multiple times without leaving a stinger. However, if you notice a stinger, use the edge of a credit card or your fingernail to scrape it out gently. Avoid using tweezers, as squeezing can release more venom.
  3. Clean the Area: Wash the sting site with soap and cold water to remove any venom left on the skin and prevent infection.
  4. Apply Cold Compress: Use a cold pack or cloth filled with cold water to reduce swelling and numb the area. Apply for 10 minutes, then remove for 10 minutes, and repeat as needed.
  5. Avoid Scratching: Scratching the sting site can increase the risk of infection and prolong the healing process. If the area is itchy, apply an over-the-counter hydrocortisone cream or calamine lotion.
  6. Pain Relief: Over-the-counter pain relievers like ibuprofen or acetaminophen can help reduce pain. Always follow the recommended dosage and consult with a pharmacist if you’re unsure.
  7. Monitor for Allergic Reactions: While the article focuses on those without allergies, it’s essential to be aware of signs of an allergic reaction, such as difficulty breathing, hives, rapid heartbeat, or swelling of the face, lips, or tongue. If any of these symptoms occur, seek medical attention immediately.
  8. Natural Remedies: Some people find relief by applying a paste made of baking soda and water to the sting site. Aloe vera gel can also soothe the skin and reduce inflammation.
  9. Stay Alert: After a sting, it’s a good idea to stay alert for any signs of infection, like increased redness, warmth, pus, or if the pain worsens after a few days. If you notice any of these symptoms, consult a healthcare professional.

Remember, while bumble bee stings are generally harmless for those without allergies, everyone’s body reacts differently. Always prioritize your well-being and consult with a healthcare professional if you’re concerned about a sting.

Anaphylaxis and Treatment

Anaphylaxis is a severe allergic response that can be life-threatening. Signs of anaphylaxis include:

  • Trouble breathing
  • Swelling of face, lips, or tongue
  • Chest tightness or pain

In cases of anaphylaxis, emergency treatment is necessary, which often involves administering an epinephrine injection and seeking medical help.

Bumble Bee Sting Symptoms Allergic Reaction Symptoms Anaphylaxis Symptoms
Pain Difficulty breathing Trouble breathing
Swelling Rapid heartbeat Swelling of face, lips, tongue
Itchiness Hives or rash Chest tightness or pain

Preventative Measures

To reduce the risk of getting stung by a bumble bee, take the following precautions:

  • Avoid disturbing a bumble bee nest or approaching a queen bee.
  • Do not wear bright colors or floral patterns that may attract bees.
  • Refrain from using strong scents, perfumes, or lotions that may attract bees.
  • When outdoors, cover food and drinks to avoid attracting bees.

Remember to stay calm if a bumble bee approaches, as swatting at it may provoke a sting.

If you know you are allergic to bee stings, always carry an epinephrine auto-injector when spending time outdoors.

Conclusion

Bumble bees, vital pollinators in our ecosystems, possess the intriguing ability to sting, a trait found only in females.

Their unique “buzz pollination” technique showcases their significance in plant reproduction.

However, with the looming threats of climate change and habitat loss, their populations face decline.

While their stings can cause discomfort and, in rare cases, severe allergic reactions, understanding their behavior and taking preventive measures can minimize risks.

Preserving these essential insects is paramount for maintaining a balanced ecosystem.

Over the years, our website, whatsthatbug.com has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.

Letter 1 – Red-Tailed Bumble Bees move into Bird House!!!

Help identify this nest of bees
Hi Bugman!
I am so grateful I found this site and I am hoping you can identify this nest of bees which have decided to take over a bird house in our back yard. Are they dangerous? Are they endangered? I hope you can help, they make me a little nervous!
Thanx a lot!
Linda Robb

Hi Linda,
Because we are feeling cantankerous, we must begin by yelling at you. Where are you???????? Insect identification is difficult enough when location is known. If we didn’t love your photo, which is awesome, we would have simply hit the delete key and moved to a letter with more substance.

If you are in the eastern U.S. or Canada, these are Red-Tailed Bumble Bees, Bombus ternarius. According to our Audubon Guide: “In early spring queen enters opening in soil to build honeypots and brood cells. Small workers develop first, visit flowers for nectar, and construct new brood cells. With warmer weather, larger adults develop.

Only young mated females overwinter.” With the current state of the world, all living things are endangered but your native bees are not rare. They are not aggressive, but you should not disturb their nest or they will sting repeatedly. Please let them live in their awesome new home.

Sorry Bugman,
I live in Portland, Oregon. Thanks for identifing our bees. I have a few more awesome photos of them if you want me to send them to you. I have never seen a bee that looked like that before.

They swarm around the front of the bird house in the middle of the afternoon when it is hot. It looks like they have some kind of a cone just inside the opening of the house. So sorry I didn’t give you more information in the beginning, it is the first time I wrote to someone about them! Best Regards,
Linda Robb

Update (05/01/2006)
Eric Eaton provided us with some assistance on this one: ” Ok, the bumblebees should be Bombus melanopygus, if my memory serves. We called them red-tailed bumblebees when I lived in Portland. That is a neat shot, one we could use on Bugguide because we don’t have that species yet.”

Dear Fred,
There are several species of Bumble Bees with red stripes on the abdomen, and we believe your individual is a Hunt’s Bumble Bee,
Bombus huntii, a species that BugGuide reports at high elevations.  The Yellow Fronted Bumble Bee, Bombus flavifrons, which is pictured on BugGuide, is also a high elevation species and like your individual, it appears considerably furrier than the Hunt’s Bumble Bee.  Our money is on Hunt’s Bumble Bee.

Letter 4 – Mating Yellow Faced Bumble Bees

Mt Washington, Los Angeles, CA
July 2, 2006
Since our internet access here at the What’s That Bug? offices is so pokey because Earthlink has downgraded us to dialup, we decided to catch up on some gardening. First we pulled out the swiss chard that had gone to seed and then decided to heat up some coffee.

A large dark flying shape caught our eye in the front yard. It landed on the zucchini. Closer inspection revealed this pair of mating Yellow Faced Bumble Bees, Bombus vosnesenkii. They have been going at it for about 15 minutes and allowed us to make use of our photographic training by capturing the action digitally.

So the milkweeds seem to be the water cooler of the insect world. We have monarchs, Japanese beetles, tons of bees (honey and bumbles), and these red mating things!

Their flowers are a pretty color and they really have a pleasant and strong scent. I’m rather surprised that these weren’t grown on purpose before the whole monarch decline. Any way, were enjoying the show and hope to get a caterpillar or two.

Dear Amber,
There is indeed quite a robust ecosystem surrounding milkweed, which is one of the reasons we created a Milkweed Meadow tag on our site recently.  Monarch Butterflies need milkweed as it is the only food consumed by the Monarch Caterpillars.  Milkweed Borers and Milkweed Tussock Moth Caterpillars are other visitors you might expect in the future.  Your mating Large Milkweed Bugs are another species that depends upon milkweed.  Many pollinators like your Bumble Bees, numerous species of butterflies and many wasps including Tarantula Hawks (mostly in western states), while not dependent upon milkweed as a sole food, are attracted to the fragrant blooms that are laden with nectar.  We will attempt to identify your Bumble Bee species.

WE keep returning to the Milkweed Meadow to document the progress there, and the Monarch Caterpillars have both vanished.  The Bumble Bee is usually there during the time the sun strikes the blooms, but we are still not certain if this is Crotch’s Bumble Bee or the California Bumble Bee.

Which Bumble Bee is it???

  We also noticed numerous tiny beetles on the milkweed blossoms.

Bumble Bee and Soft Winged Flower Beetles on Milkweed

Alas, the old model digital camera we are using does not have a macro setting that will allow us to get closer.  We would like to identify these beetles.  After the fact, we had a terrible thought that they might be the Walnut Twig Beetles that are spreading the 1000 Cankers Diseaseto black walnuts in the western states. 

This matter will take additional research.  Many beetles with wood boring larvae feed on pollen as adults.  We should return tomorrow morning and collect a few specimens to take to the Natural History Museum of Los Angeles County.

These are pretty easy to subfamily level.  They are soft-winged flower beetles in the family Melyridae, subfamily Dasytinae.  After that it gets really messy, really fast!  Nobody wants to try to ID them even to genus…..

Letter 7 – Northern Golden Bumblebee

Michigan Northen Golden Bumblebee?
Hello, Bugman:
Large, fuzzy and almost solid yellow bumblebees have been buzzing around our S. E. Michigan gardens for a few weeks now. I’ve never seen one so big and solid yellow before; about 1″ long, possibly a queen?

They are attracted to the zinnias in our planter box. After looking online to identify it, I believe it may be a Northern Golden Bumblebee. I looked through your on-site bee photos and don’t remember seeing one like this in your galleries. Could you confirm if this is indeed a Golden?

We believe that your identification of a Northern Golden Bumblebee, Bombus fervidus, is correct based on images posted to BugGuide. For more information on this species, visit Discover Life.

Letter 8 – Orbweaver eats Bumble Bee

About your site
Hello! I just wanted to let you know that you have the most helpful and organized site I have ever been on. I’ve spent a good 20 mins. looking at other websites attempting to find out what kind of spider I had next to my back door. After a few moments on your site I found her (or him), turns out she is a Orb Weaver, she is very interesting to watch.

While on a field trip for biology I found a very unsual caterpiller and again, only a few moments and I found he was a White Marked Tussock Moth Caterpiller. I will be using your regularly since I am always finding interesting bugs. I am also sending a pic of the Orb Weaver munching on a large bumblebee. Enjoy, Thanks again!!!

Hi Caitlin,
Thanks for your thoughtful letter. We do get our share of letters telling us how difficult our site is to navigate and offering us suggestions on how to make it better, so it is nice to hear you call it organized.

Gentle Readers,
Obviously Daniel is spending more time in the garden than he is at the computer, but it is raining this morning and it seemed like a good time to post some of your requests as well as some of Daniel’s sightings. 

Despite the multitude of Japanese Beetles, this Perplexing Bumble Bee, Bombus perplexus (which we identified on BugGuide) is still able to find plenty of nectar in the yard thanks to Pearl’s row of Monarda across the back garden and the many varieties of Hosta that are currently blooming.

Dear Nick,
Large Robber Flies are arguably the most adept aerial predators in the insect world.  Dragonflies are larger, but they don’t tend to prey on larger insects, mainly satisfying themselves with mosquitoes and smaller prey.  Not so large Robber Flies that tend to prey on bees and wasps. 

Your individual is a Red Footed Cannibalfly, Promachus rufipes, a species that begins to make a regular appearance among our identification requests beginning in June, and continuing through the hot summer months.  The Red Footed Cannibalfly is also called a Bee Panther.

Letter 15 – Silken Fungus Beetle engaging in Phoresy with a Bumble Bee in Sweden

Question
Hello,
I heard about your site in German TV and so I remembered a photo I’d taken in 2006 in Sweden. That little bug is “torturing” a bumble-bee by pinching its proboscis. Can you tell me what ‘s happening there? Kind regards
H.Koslowski

Hi H,
You are the second letter we received today that mentioned seeing our site on television. Our first job is to identify your beetle. This appears to be a Flea Beetle in the tribe Alticini, but we would like verification. Hopefully, Eric Eaton can substantiate that. This diminutive beetle cannot possibly think the bee is food, but it might be hitching a ride, a phenomenon known as Phoresy. We hope to get clarification on that from Eric Eaton as well.

Hi, Daniel:
That is a really remarkable shot of the beetle clamped onto the bumble bee! It is not a flea beetle, or any other type of Chrysomelidae leaf beetle as far as I can tell (flea beetles get their name from their ability to jump, not because they are parasitic). I suspect it is some kind of sap beetle (family Nitidulidae), some of which can be abundant inside flowers.
Eric

Update: (02/08/2008)
Hello Daniel,
I think I have a proper guess what sort of a beetle this might be! It belongs to the genus Antherophagus (fam. Cryptophagidae, silken fungus beetles), which has three species in Sweden, all developing in nests of bumble bees.

I think this one is A. pallens (Linnaeus, 1758) (~4 mm), which is the most common species of the genus. All species visit flowers to clamp onto bumble bees to hitch a ride and infest their nests. But the larvae are supposed to be harmless to their hosts, feeding on the bees’ faeces. So this is a perfect example of a picture showing the start of a Phoresy! Best,
Bengt Andersson Sweden

Sonoran Bumble Bee

Dear Rachel,
We wish we had your luck.  Daniel hasn’t seen a Bumble Bee in the WTB? garden for quite some time, despite there being numerous other native pollinators.  We believe based on images posted to The Natural History of Orange County that is is a Sonoran Bumble Bee,
Bombus sonorus.  According to Accent on Natural Landscaping:  “Male bees do not actively collect pollen, only the queen and worker bumblebees do. They transfer the pollen they collect to the sacs or baskets on their hind legs to make it easier to transport back to the hive. Bumblebee pollen sacs or baskets are known as corbicula.”

Dear JR,
Your Tricolored Bumble Bee, does build a nest underground.  The fact that you have never seen them before this year may be that either you just never noticed them, or that the local population is small.  Some insects do not range far and it is possible that the species might be common a quarter mile away, but virtually nonexistent in your immediate area.  Thanks for sending your awesome photo.

Letter 22 – Tricolored Bumble Bees

Are these red tailed bumble bees or not?
Bugman,
We just discovered this nest in a small birdhouse in one of our trees. They look to me like the same bees Linda Robb wrote to you about, however, my wife disagrees. Linda was in Portland, we live in the Seattle area. We spent quite awhile near the nest taking photos and they seemed pretty docile.
Thanks,
Ray Elliott

Hi Ray,
These are Bumble Bees, and they do have red on them, but we just learned that the common name Red Tailed Bumble Bee belongs to a Eurasian species, Bombus lapidarius. We believe this to be the Tricolored Bumble Bee, Bombus ternarius. BugGuide lists the Tricolored Bumble Bee as ranging from “Yukon to Nova Scotia, south to Georgia; widespread in the United States but rarely observed south of Pennsylvania.

We then located a wonderful website of Bumblebees fourn in North America that shows body marking comparisons. They list the range as “Yukon east to Nova Scotia, south to Georgia, Michigan, Kansas, Montana, British Columbia. ” Another possibility is that your Bumble Bee might be Bombus huntii, a species listed on BugGuide with no common name. We may have to correct our archive regarding the Red Tailed Bumble Bee when we have time.

  1. she must have been really very worried being trapped against a window after hibernation which is why she was attempting to warn off what was getting in the way… I hope you released her outside so that she could find a place to nest…. bumblebees are not normally aggressive but they do panic if trapped…..

  2. I have a birdhouse that chickadees nest in every spring. When checking this year a hissing sound came from the hole. The chickadees had created a nest inside as I clean them out every year but the only thing in the birdhouse was this bumblebee with a red stripe. It really hissed when I shook the house. I cleaned the house and let it go on it’s way. I know I probably should have left it but I have so many infestations of bees and wasps in my large yard I cannot garden without getting stung and the stings are becoming more allergic in nature with severe swelling. But I wondered why it was nesting alone and in the birdhouse.

  4. We are in Utah in the Salt Lake area after two days of searching to identify and seeing the photo sent to you, I would swear that we have red-tailed bumblebees in our raspberry patch area and some have burrowed down in our compost pile. My roommate who is allergic got a nasty sting on her face and then after a third attempt of moving compost to her garden area one got down in her shirt and stung her on the side.

  5. I live in Shelton Washington and found these bee’s in my birdhouse on the back porch 2 days ago. We did not know what they were. What we did know that everytime we went out on the porch they started swarming and chased my mom in the house. My mom ran into the bathroom until I got it out. Yesterday they were swarming so we put a nail on the big tree on corner of house but they swarmed horribly and we set it down on the compost bin post because there are 3 other bird houses already secured there. Well later 2 bee’s came to old location on porch and are still buzzing aroung mad on the back porch because they cannot find the home. What do I do?

    • This board is full of animal lovers. This is bound to make someone mad so it’s hard for them to chime in I believe. I read you cannot relocate their nest. So it must be left alone or destroyed. I enjoy that you want to help them find their nest but you did what you could and the need chose a bad location to create their home. I personally have a bird house on the side of house and I walk up and take pictures of their nest and they leave me alone. It could be due to the fact half the time I am smoking a bowl so that may calm them or what not. I am no bee expert but I was surprised to read that they are more aggressive.

  7. I just discovered bees in one of my 2 birdhouse s on my porch (the other is used by black capped chickadees). I was sweeping and accidentally jostled the house. I then heard sound like a dog whimpering and looked in without thinking. Wow. One and then more camp out & chased me to the other end of the porch. Trapped 10 feet from the ground, I waited till they calmed down and then made a run for the only door which was inches away.

    Then I used this google search & found you right away:
    “bees in my birdhouse-brown+yellow+red spot on abdomen”
    Thanks for helping me name them. I will take good care of them-important pollinators we are lucky to have.

    • I just found a nest of these red tailed bumble bees in an old bird house. Its attached to a post next to my patio. My dog was trying to get to them fortunately the bird house is to high for him to get to. I will leave the alone and let them do their thing. Anthony in Sedro Woolley, Washington(State not D.C.).

  9. Thank goodness I found this. Same exact thing happened to me. I am glad to know I am providing a healthy environment for the bees to enjoy.
