The eggs the female lays take approximately 36 days to develop to an adult. Unlike bumble bees, carpenter bees are solitary insects. The adult carpenter bees hibernate over winter, typically in abandoned nest tunnels and emerge in the spring to feed on nectar. Carpenter bees do not live in nests or colonies. Instead, female carpenter bees bore circular holes through soft wood to lay eggs and protect their larvae as they develop. Male carpenter bees do not sting, but they are territorial and oftentimes the gender that most people come into contact.
The males will hover closely to people, especially attracted to sudden movements, but do no more than create unnecessary fear. Female carpenter bees sting; however, it is on very rare occasions and requires provocation.
The National Pest Management Association is sharing helpful information about stinging insects and tips to prevent any painful stings this summer. Although the Asian giant hornet may not pose a significant threat to most Americans, the National Pest Management Association NPMA is reminding the public about the serious health threats that native stinging insects pose to the entire country.

Unfortunately and luckily aesthetically , it can be difficult to assess the extent of their galleries just by looking at them. If you are seeing a lot of carpenter bees, chances are there are some impressive tunnels in your carport.
Most real and overwhelming damage comes from woodpeckers trying to excavate your pollinating friends. I would recommend you keep an eye out for curious woodpecks, and if they start showing an interest in your carport, hang some reflecting markers or stickers to help keep them away. First off, you are correct that carpenter bees prefer to use holes that they excavate themselves.
They do also re-use carpenter bee galleries, however they are normally of larger diameters than those found in man-made bee houses, which are made for solitary mason bees, leafcutter bees, and other beneficial insects like solitary wasps. Carpenter bee galleries are also normally much longer than the short space allowed in man-made solutions like the one you linked.
Houses like that will not attract carpenter bees, rather the beneficial solitary wood nesting insects that are already in and around your property. I would not recommend you purchase the house you linked, however. This is for several reasons. First off, it is difficult to gauge the diameter and depth of the holes provided.
Each species tends to prefer specific diameters, and many commercially available houses neglect to make their holes actually livable for North American native bees and wasps. The tunnels need to be at least 6 inches deep- anything shallower, and the ratio of males to female eggs laid becomes skewed, which is very bad. They can be longer than 6 inches, however this is another aspect that many commercial houses miss. It is best to have a housing solution with a closed off back, to help ward off pests and predators.
I recommend you either purchase a man-made native bee house somewhere where you can see it in person, so that you can take a look at the diameters and measurements for yourself before buying, or from a seller who is clearly invested in making houses that take the lives of the creatures they are attempting to attract into consideration. Thank you for making sure you are doing the right things for the important pollinators and other insects in your area!
I have a screened in porch that is above a carport, so the gaps in the floorboards are big enough for carpenter bees to get in from below. I think they are nesting in the wood from the underside, which is fine. I have been working from home for a few weeks out on the porch, and I notice that the carpenter bees have a strange habit of coming up into the screened in porch through the floor and getting trapped.
Once they are inside, all they do is crawl around on the screen seemingly looking for a way out. I am starting to form a theory that this mainly happens when the sun is shining on the screen. On cloudy days and in the evening screen faces east they do not seem to get trapped. However, one days when they do, I can trap and release and then presumably the same bee will be back within minutes.
I was wondering if you had any insight into why this is happening. I will do some digging, and reply back if I find any known reasons why they are wandering up during the day.
Maybe it is also cooler, and they are looking for some respite from the sun before realizing they are trapped? Would putting a carpet down be too much of a hassle? That might keep them out.
Thank you for trying to keep them from getting stuck, and keep us updated on anything you try that works! However, it has chosen to burrow into the part of the cradle that is right next to our back door. But I would like it to not be so close to our back door so I can go outside without freaking out. We are going to try using citrus water boiled citrus in water, cooled, then poured over the post as well as the speaker method. Are there any other methods that you suggest to either move the nest wood cradle or to encourage it to leave?
Thanks for your message! Make sure you pick music that bees like, maybe some Queen or Sting. As mentioned in the blog, try to have attractive nesting sites nearby if possible like standing or fallen dead trees, limbs, or wood piles.
You could also move the wood cradle, like you said. Move it on a cool night, to make sure the bee is inside and slowed down due to the cold. Wear a hat and gloves, however I doubt the bee will give you any trouble. Keep us updated, and good luck! But the music did keep it at bay after it flew off and it allowed us to work. We covered the cradle with some lime water, and poured some over the wood for good measure. We put a piece of lime rind in the hole as well.
He did come back to investigate, but did not like the lime and left. Thank you so much for all the info. We have many flowers and a garden. This year our carpenter bees decided to make a home on our deck, in the newly put up roof rafters. She started yesterday. My Mom has always disliked them. So glad I found your info.
She has continued her work today, as the wood shavings are everywhere. Glad she is there. We have many wasps, too, but they never seem to bother us. We can all get along and have many blooms this year. God bless you! Thank you for your comment, and for giving your carpenter bee friend a home. I think you will learn to like and appreciate them even more as they live close to you! I just moved into this home in November.
I am loving all of the flowers that are inherent to the property — lilacs, iris, lilies, etc. However, I have jokingly been calling my screened in porch a Bee Hospice. So I started googling around to see what I could find. I have one or two carpenter bees show up daily, crawl around on my screens I leave the door to the outside propped open at all times so my Bernese Mountain dog can wander in and out and in a day or two at the most, they are dead on the floor.
I rarely see them fly. I was surprised to see how long they live, but am sad to see them dying on my porch. I have plants on my porch as well, chenilles, gardenia, ferns and a couple shamrocks. So I think they are just wandering in. It was wonderful to read about what great pollinators they are. So my question is: is there something that is causing them to die on my screened in porch? If so, I would love to fix it. If they are just coming to die in my porch because it is peaceful and surrounding them with all the yummy smells of my gardenia, I am happy to welcome them to my Bee Hospice.
Interesting- we have heard about carpenter bees getting stuck in screened in porches from other readers, and are not quite sure why. Maybe they are seeking some cool shade, or are looking for a new nest, and get stuck.
Have you been able to notice if the dead bees have yellow spots on their foreheads? I would be curious to know if the stuck bees are males, females, or a mix of both. Males typically have those large, yellow dots on their faces. If you could take a tally of any bees you find, and if they have facial dots, please report back! Until then, leaving the door open as you are already doing is excellent. I would also recommend placing a shallow dish filled with water somewhere on the porch, so that any stuck bees can get a drink if they need.
I have no idea where the nest is!! How can I figure that out? I also love watching him carry away any wasps that get too close. I guess they can grab on. I wonder why he moves away when I come to take a closer look at him. Any help appreciated! That definitely sounds like a male- they tend to stake out their territories and stick to them during the day. If you can get a closer look, males tend to also have a large yellow dot on their forehead, which makes their identification easier.
They have been found to be able to recognize their neighbors, though, and they are less aggressive towards those they recognize. Males typically pick one of two locations for their territories, which are usually around 10 feet in diameter or so. Sometimes they will stake out a location near a nest, so that they can easily find females as they travel to and fro during the day.
Another is prime flowering sites, which sometimes are pretty far away from the nest. If you have a healthy supply of flowers in and around your property, your buddy could have claimed them as his territory.
In that case, it will be very hard to find the nest- studies have found that carpenter bees have been able to find their nest from up to 7 miles away, so they can travel extremely far to get forage if they find a good spot. In some cases the males might not even live in the nest at all, and might shelter in the landscape near their territory.
In any case, your space has been deemed attractive enough for his territory, so I would definitely take it as a compliment. Thank you for your comment, and please keep us updated on how your bee friend does this year! Hi and thank you for the reply! I do have a flower garden directly underneath the porch where he hovers.
Great for pollination. I sit about 5 to 6 feet from him on the porch. He darts up very often removing those who fly by. I really like that he keeps the wasps from coming near me.
I do live in a highly wooded area, so a nest coukd be in the trees somewhere. They seem to fight a bit. Other than those two, I see no others.
Wonder where he is. Do they move on after some time for any reason? Depending on how their season has been going so far, and how significant the impending weather is, your bee might be taking a day off from most of his duties. They almost always live for longer than a week or two, though, so keep your eye out for his return!
Hi, thank you! The males only live for a week or 2? This bee landed on the underside of the porch wood constantly, and seemed very interested in the wood.
I seem to have carpenter bee friends who have started holes in a part of my porch roof. They unfortunately are right in front of my front door so I am always terrified to leave, even to grab the mail LOL Do you think they will get aggravated at my family since we are so close to where they decided to stay?? Because of their large size and curious nature, it is common to be a bit afraid of carpenter bees. But you do not need to be scared, because they are some of the most docile insects around.
They will not attack you for being close to their nest called a gallery , unless you physically try and tear into the wood, in which case you are probably asking for it. The females, which do have stingers, are not agitated by people hanging around their galleries. They should not bother you at all. The males, which can usually be told apart from females due to a large yellow dot on their forehead, do claim territories that they keep clear of other animals whenever possible, including humans.
Males are very charismatic and will get in your face to challenge you, and they will also follow you around and observe your movements through their territory. You do not need to be afraid of them either, however, since the males do not have a stinger and are all buzz and no sting. The most offensive encounter with a male will end with them headbutting you out of curiosity, however they will not sting or bite you.
Studies have actually found that males are able to remember their neighbors, both insects and other animals, so eventually the males in your area will learn to remember you and give you less of a hassle when you wander through their territory. Please keep in touch and let us know if you have any other questions or concerns about your new roommates. Thanks again for reaching out instead of simply killing these important insects! Hello my wife and I have lived in our home for about 10yrs.
They have been there every spring since, and I would agree, they are truly fascinating creatures. We live near buffalo, ny so we enjoy our warm months on our patio adjacent to garage where bees live. They definitely recognize us, I think a little more every year. As I was misting birds, they appeared to be attracted to it, so I continued to mist the bees.
Thanks sorry so long. They also dislike extreme heat, and probably enjoyed the cooling mist you provided. Maybe they were even able to get a drink as well. I will have to try it for myself! Thank you for sharing your story, and for caring about your local carpenter bees!
They do produce a honey-like sugary product, however they only make it in small supplies that they use to feed their young. I just found your website, and have been reading post after post. It is wonderful what you are doing. Thank you for your comment, glad you found us!
It is always good to hear stories of people living alongside their local carpenter bees. Have a great summer, and please post again with any questions or concerns you might have about these important insects.
I love these bees, I thought they were bumble bees at first. They are so sweet and gentle. I can touch them and they are fine with that. Sometimes though, they seem like they are drunk? Anyone know why,. This can also be seen in honey bee swarms, since the swarm feasts on honey before they leave the nest in search of a new hive, making them all extremely passive. It is probably similar to the effects of a few drinks. I found this totally by accident. Will either of these deter pollinators from my plants?
Just trying to keep the squirrels and raccoons, from taking all of our food. Thank you for your time and have a wonderful day. Insect pollinators of all shapes and sizes will be undeterred by your cedar framing and chicken wire. Have a good day! Hey there! So glad I found this post years later. We recently removed an old wooden pergola that had at least a dozen carpenter bees working on it. I was being careful not to cut near any holes and I saved the wood boards with active bees in it.
The rest of the wood will be discarded. Any idea when would be the safest time of year to do so? Its currently March in Florida so spring is well underway. In our experience, the best way to get carpenter bees to leave existing nests is to move the boards into a sheltered space in a wooded area forest if possible. That should hopefully encourage them to leave their boards for some more natural digs.
At the end of the season, around August, they should be empty and ready to be discarded if you so desire. Thanks again, and please be in touch about what you do and how it works! Thank you for all the information and encouragement. We also greatly enjoy the ambiance carpenter bees can bring to an outside area. Thank you for reading, and for leaving a comment! Thanks for your comment, and for trying to help your new friend! They will eat sugar water, around a sugar to water ratio, in a spoon or shallow dish.
As soon as your local temperatures stop dropping below freezing I would let your bee outside, they are very tough and can survive in some pretty cold weather. As far as the sex, besides the forehead dot it can be hard to tell.
They do sleep and relax, and some scientists think that they dream as well. As long as it is able to be released soon your bee should probably do just fine.
You have now discovered the reason that we cannot burn wood in our house without very carefully looking it over first- too many stowaways! I just stumbled across your website because I have carpenter bees all along my house.
They truly are non aggressive and chase off other insects. The only problem I have is that we live in a very wooded area with loads of trees and they still choose our house to nest in — which leads me to believe that there might be too many? Thank you for the comment. Some carpenter bees naturally venture out beyond their original nest site, and so a consequence of having great natural habitat for them is that some will eventually come into contact with your house.
It sounds like your bird feeder male might have picked an unlucky spot for his territory. I would guess that the problem will take care of itself before too long, when the bee gets too bold and approaches the wrong bird!
Please reach back out if the bee gets more ornery towards your feeder friends, or if you have any other questions. I found your page during research about the bees. My old still fruiting peach tree has some dead branches which have been used by what I thought were a couple of bees for the past two years. I tried to saw off a dead branch today to get rid of the wood and many bees flew out.
Black females and golden males. For the first time, I saw the labyrinth of channels for the galleries made and it is impressive! I decided to leave part of the dead branch there for now lots of buzzing inside so they must still have channels to live in.
Half the branch which I did remove is on top of the compost bin to allow for exit if any bees are still in that part. I guess my peach tree will be home to the group until it stops fruiting and needs to be cut down. Yes, it sounds like your peach tree will be a local carpenter bee haven for years to come, at the very least.
Thank you for deciding to leave these important and powerful pollinators where they are! Good day, I found a carpenter bee on the ground yesterday at dawn. He seemed quite lifeless. I placed him in a box overnight and put him out in the sun again this morning. He tried to fly, but immediately fell to the ground. Any idea to what the problem might be?
Is there anything I can do to help him? Thanks for the comment, sorry for the delay in responding. How did your bee friend fare the next day? It sounds like the bee you found might have been injured, exposed to pesticides, or simply very old and expiring.
Feeding them a mixture of sugar water can sometimes rejuvenate them enough to get flying again. Thank you for trying, and keep in touch with any other questions about carpenter bees! I absolutely love these little creature we have the everywhere.
But i would like to know if there are any creative and fun habitats or homes that we can build just for then to use year after year. Kinda like you would a bat box but just for these little guys? Thanks for the question, we love them too! If you make some of your own, please be in touch and let us know how it goes!
I would love to find a way to continue to coexist with our carpenter bees. We have an old farmhouse and barn that we rent out to other tenants. We plugged the wood siding of the farmhouse a couple of years ago and then added vinyl siding to that to insulate it as well as encourage the bees to live somewhere else. The farmhouse was already a bit run down when we bought it. Each spring for the past years they re-emerge, more numerous than before.
I am concerned they are compromising the stability of the barn. Any other thoughts on how to minimize the damage to the barn? Today I observed what seemed like hundreds of bees all over the barn — every entrance, the rafters, the roofline, etc. How is the vinyl siding on the farmhouse working at keeping carpenter bees from moving in?
For large, heavily populated buildings like your barn, an option is to remove and relocate the most heavily affected pieces to a sheltered space in a nearby forest. For best results, move them over 7 miles, as they have been found to be able to find their way back home from that far of a distance! Although carpenter bees are very docile, I recommend moving them at night, with gloves and a bee veil, or a hat and safety glasses.
Move them in the bed of a truck if possible. Please let us know what you decide to do, and how it goes. I have 2 bee traps. If I catch any in the traps, can I relocate them?
My question: how far away miles? Thank you for trying to relocate the carpenter bees you are catching. Yes, they can be moved, but studies have found them able to return to their nest from as far away as 7 miles, possibly from landmarks but their true wayfinding abilities are still unknown.
If possible, I would move them to a forest or other natural setting over 7 miles away. Thank you for the quick response. There is a nature park 10 miles from me.
I have 2 mason jar traps. Is that correct? My plan is to hang them from a tree using a strong cord. Sound right?? Any other suggestions is greatly appreciated. Try and secure it as much as possible. But they are doing so much damage to my back garage door frame and shed nearby that I decided to move them.
Plus they are driving my dog crazy! Will the young survive if they have hatched at this date? There are no bees to bring pollen to the nests? Some of the young might perish, however the life cycle of young carpenter bees is still largely unknown. I think the bees that remain will be ok. Thank you for not outright killing your carpenters! Thank you for your reply! There are still about three female bees returning to the nests.
I see no males. If I need to move the bees again in the future what is the best time of year to do so? I want to do the least harm to them! Thanks again for keeping their survival in mind as you try to remove them from your garage door! This is a myopic statement and post.
I have a converted barn home from Original barn wood. I have had to commit genocide against these horrible creatures with a backpack gas-operated sprayer, custom-size drill press plugs on each hole after dusting. All to preserve a historic structure of an original founder. I have tried all green solutions.
Thankfully a shed, but still on the historic register. Douse it all and kill them all. They belong nowhere other than forests. Your home is worth more than this rhetoric. You worked hard for it. If you have a brick home with a wooden deck, fine. Spriggly, I love bees and grew up with admiration of the social insects. Carpenter bees are not social. Unique among the bee community in this way.
All animals can become pests depending upon circumstances. Please consider the impact of one-sided arguments. There are structures that cannot suffer these bees. I do not delete posts with opposing viewpoints, but I do respond with a retort so that others with the same bone to pick can hopefully learn as well.
I appreciate you caring about the history of early American structures. As you have undoubtedly learned already, maintaining historic structures, especially those made primarily of wood, involves a slow and costly battle against a multitude of environmental stressors that always moves towards the inevitable.
Carpenter bees are but one of these stressors- and in fact, normally it is predators like woodpeckers who do the most damage as they attempt to access carpenter bee galleries. Please also remember the rains and winds working away at your buildings. Since you are clearly a lover of American history, I would like to remind you that carpenter bees have helped American ecosystems develop over likely hundreds of millions of years, which is also before George Washington was born.
I am curious for some further details of your campaigns against your carpenter bees. What kinds of natural areas are around your property? This article and comment section does not ever state that carpenter bees belong anywhere other than their natural habitat, forests. Prevention is ideal for avoiding damage without harming valuable pollinators.
