Carpenter bees, just like other bees, are essential to our ecosystem since they are effective pollinators. However, these insects are loud and can be a nuisance around your home. Additionally, carpenter bees bore large holes in your potting table, patios, fence, and other outdoor wooden structures, reducing their aesthetic value and compromising the structural integrity. For this reason, most people try to eliminate the carpenter bees whenever they become too many or start causing destruction. Read on to understand what these insects are and how to get rid of carpenter bees.

What Are Carpenter Bees

How to Get Rid of Carpenter Bees: Best Methods to Try

Also known as wood boring bees or mason bees, carpenter bees are solitary insects that build their nests in wood by boring holes, especially on natural and unfinished wood. After boring the holes, the bees discretely divide cells for their young ones. Also notable is carpenter bees aren’t as social as other bees and typically live alone while other species establish huge colonies.

What Do Carpenter Bees Look Like?

Carpenter bees have a black and shiny abdomen with their size ranging from ½ inch to 1 inch long. Male and female carpenter bees have different appearances. The females of the species have completely black faces, while their male counterparts have a yellow spot on their faces. Additionally, female carpenter bees have stingers while males don’t. However, females only sting when provoked.

How Do Carpenter Bees Drill Holes?

Carpenter bees typically drill holes in untreated wood. They prefer soft wood like pine, cedar, and redwood. When drilling holes, they vibrate their mandibles against the wood until they create a hole while allowing the resulting frass to fall to the ground. Frass is the saw-dust-like substance produced when the bees bore into wood.

Carpenter bees drill roughly half an inch into the wood, then turns 90 degrees, creating a long tunnel that follows the wood grain. A single tunnel is between 6 and 12 inches long. They can also take about five to six days to drill a hole.

The holes drilled by carpenter bees on softwood are about ½ inch wide. These nests typically have many sub-channels extending from the central tunnel, with the whole structure being called a gallery.

Carpenter Bee Life Cycle

A carpenter bee has four main life stages: egg, larva, pupa, and adult. The egg is the initial life stage of a carpenter bee. Before a female lays eggs, it has to drill holes to prepare a habitat for the young ones. After drilling the holes, she subdivides them into sub-sections, known as brood cells, laying one egg in each and filling it with food.

The next stage of a carpenter bee’s life is the larva. A larva develops when the egg hatches, and it survives by eating the food left in its brood cell. Additionally, the tunnel is safe and secure for the larva, allowing it to develop.

Next is the pupal stage. The immature bee can be quite fragile during this dormant time. It is nonetheless safer than other metamorphosing species because of its elaborate nest. A carpenter bee’s larva doesn’t need to create a cocoon like other insects. Instead, it undergoes its transition while still inside the brood cell.

After about seven weeks, the carpenter bee develops into an adult and leaves the nest to explore the world independently. When the carpenter bee fully develops and leaves the nest, it will either go back to its previous nest or find another abandoned one to spend winter.

Carpenter bees have a life span of up to three years. Once the male and the female bees mate, the former dies immediately while the latter dies shortly after laying eggs.

What Do Carpenter Bees Feed On?

Carpenter bees don’t consume wood when creating tunnels, unlike termites. Instead, they feed on nectar from flowers like most other bee species. The insects can access the nectar by biting into the flower bases, although they still end up pollinating some flower species. Before the carpenter bee larvae can develop into adults, they feed on bee bread which females make by combining pollen and nectar, and some of their excretions like saliva.

When Can You Find Carpenter Bees?

Most people see carpenter bees during spring when they are most active. During this period, they come out of their nests to begin mating and reproduce and build new nests. However, the carpenter bee’s seasonality can vary depending on where you live.

Carpenter Bees vs. Bumblebees

How to Get Rid of Carpenter Bees: Best Methods to Try

Carpenter bees and bumblebees have a striking resemblance, and people often confuse the two. However, on closer inspection, the two are fairly different. There are several features that can help you tell these insects apart, including:


The best way to differentiate between a bumblebee and a carpenter bee is the appearance of their abdomen. Carpenter bees have a black, shiny, and bare abdomen. On the other hand, bumblebees have a hairy abdomen. Additionally, bumblebee abdomens are lined with black and yellow stripes.


The size of a carpenter bee ranges from ½ to 1 inch, while the bumblebee’s size ranges from ¾ to 1 inch.


How to Get Rid of Carpenter Bees: Best Methods to Try

Bumblebees and carpenter bees have different lifestyles as well. Bumblebees are social and live in hives with others of their kind.  However, their dwellings are smaller compared to honey bee hives. Their colonies can be found in discarded bird nests, beneath logs, or even underground. Conversely, carpenter bees drill holes and build their nests in wood, with their lives mostly being solitary. They might also reside in rodent-made holes in abandoned wood.


Another factor that differentiates bumblebees and carpenter bees is their behaviors. Bumble bees are generally not aggressive toward people and will only become hostile if they perceive a threat. However, only the female bumble bees have the ability to sting.

On the other hand, male carpenter bees can be aggressive despite not having stingers.  They may try swooping down on you to protect their nest if you approach too closely.

Like bumblebees, only the female carpenter bees have the ability to sting. Nevertheless, if you have an allergy, both carpenter and bumblebee stings can cause severe reactions.

What Harm Can Carpenter Bees Do

Carpenter bees drill holes in your wooden structures, eventually weakening them. For a wooden home, this can result in the frame warping, damage to the walls, drooping ceilings, and even sagging floors.

Carpenter bees also have the ability to weaken outdoor stairs by boring holes in them. If you place extra weight on damaged stairs, they can break, leading to severe injuries. These injuries may also be expensive to treat.

Besides causing structural damage, carpenter bees can also cause water damage. If moisture finds its way into their galleries, it makes the wood rot. This problem is particularly common if carpenter bees bore holes in your house’s wooden siding.

Another sign of damage that carpenter bees leave on your home is surface stains. When these insects excrete, their feces may stick on your house’s walls. If not cleaned early enough, they may leave permanent stains, reducing your home’s aesthetic appearance.

Finally, carpenter bees can attract insect-eating birds into your home, leading to further damage. When these insects bore holes in your home’s wooden structure and lay eggs, they will hatch into larvae that birds try to feed on. In the process, they may enlarge the holes making your home unstable. The holes may also reduce your property value.

Signs of Carpenter Bee Infestation

Carpenter bees are among the most destructive pests around. While they don’t arrive in a huge swarm and cause mass destruction all at once. These insects slowly damage your home over time, and you may fail to notice until it’s too late. For this reason, it’s crucial to identify a carpenter bee infestation early if you encounter one.

Read on to understand the common signs of common bee infestation.

Buzzing Sound in Your Walls

When carpenter bees infest your home, they’ll immediately bore holes in some of the wooden structures. During the process, they produce a grinding sound. If you notice grinding noises emerging from your walls and other pieces of woodwork, you may want to call a pest control expert. However, these noises do not necessarily mean that you have a carpenter bee infestation. The noises may also be caused by other household pests like termites and carpenter ants.

Bee Excrement

How to Get Rid of Carpenter Bees: Best Methods to Try

You may even notice yellow-brown stains on the wooden surfaces in your home. These stains are caused by carpenter bee feces. Removing carpenter bee feces stains can be difficult even when you use the best power washer. Also, using harsh chemicals can damage your wooden surfaces. Therefore, it is advisable to seek professional assistance.

Sawdust Piles

When carpenter bees drill through wood, they produce frass which is basically a miniature version of sawdust. After some time, frass accumulates in heaps below the area where the holes were made. You may also notice frass adhering to door frames, windows, or other surfaces near the region where the bees drilled into the wood.

Round, Smooth Holes in Wood

How to Get Rid of Carpenter Bees: Best Methods to Try

The most obvious indication of a carpenter bee infestation is the holes they bore on woods. Often, these insects bore circular, smooth holes that make it easy for them to pass through. These holes are unique compared to those drilled by other insects. They can be on the underside of wooden boards. If carpenter bees follow the wood grain on the roofline board, you may even see an outline of the tunnel.

Presence of Insects

If you notice bees buzzing near your house, you may be experiencing a carpenter bee infestation. Once you spot these bees, try to check their appearance. If the insects have a black and shiny abdomen, you may be dealing with carpenter bees. Another thing that you should note is their location. Carpenter bees like staying in wood, especially unfinished wood. Therefore, if you notice bees gathering under your porch, near your roofline, or around any unfinished wooden structures in attics, basements, or crawl spaces, those are likely carpenter bees.

Structural Damage

When carpenter bees infest your exterior wooden stairs, they can become weak and can easily break. These insects may also make your balcony or deck railing weak.

Getting Rid of Carpenter Bees

Here are some possible ways to get rid of carpenter bees for good.

Use Pesticides

How to Get Rid of Carpenter Bees: Best Methods to Try

The best way to get rid of carpenter bees on your porch is by using pesticides. Once you identify the affected area, apply the pesticide. Spray into the exterior parts of the galleries. The chemical will spread deep into the insects’ dwelling and kill the bees once they come into contact with it.

Carpenter bee pesticides can come in the form of a liquid or spray. When applying liquid pesticides, use a compressed air sprayer to ensure the chemical reaches the targeted area. On the other hand, pesticide sprays already come in a compressed air can. All that’s left is to press the nozzle. Find out about the best bee sprays in your region to help make a good selection.

When using pesticides to kill carpenter bees, you need to be careful. First, follow the application instructions as indicated by the manufacturer. Usually, these instructions are written on the bottle or a leaflet included in the packaging. Also, ensure you follow all the safety precautions, such as wearing protective gear. Otherwise, the chemicals may cause injury and other health problems.

Finally, don’t overuse the pesticide. For best results, apply pesticides at intervals of three to four weeks.

Use Vinegar

If you are looking for ways to get rid of carpenter bees naturally, consider using vinegar. When using vinegar to get rid of carpenter bees, mix one cup of highly concentrated vinegar with two cups of water. Pour the result into a spray bottle and spray the mixture directly into the galleries.

The smell of vinegar seems to have an adverse effect on carpenter bees, often prompting them to move away. Additionally, if the carpenter bee larvae come into contact with the solution, they die. If you use a highly concentrated solution, it should kill the insects it comes in contact with almost immediately. However, for people who want to get rid of carpenter bees without killing them, a less concentrated solution should be enough of a deterrent.

Nevertheless, getting rid of bees from your porch with vinegar is only a temporary solution since the bees may come back once the solution dries up. Therefore, you may want to combine this method with other techniques.

Use Bee Traps

How to Get Rid of Carpenter Bees: Best Methods to Try

Another effective DIY solution to get rid of carpenter bees is using traps. A carpenter bee trap is a pre-drilled wood block fastened to a plastic bottle or a glass jar. When you get a bee trap, hang it near the area where the bees like to hang out.

A carpenter bee trap closely resembles the insect’s nest. Therefore, when the bees spot the hole, they will crawl into it and end up in the glass jar or plastic bottle. Eventually, they suffocate and die. Carpenter bee traps can kill many bees, and once the bottle is full, you can unscrew it and dispose of the dead bees.

Use Dust

One of the best methods to get rid of carpenter bees under the deck is by using dust insecticides. This method can also help you get rid of the bee’s nests.

You can apply dust insecticide the same way you use a spray insecticide. First, aim at the hole and release as much dust as possible. This way, all the bees inside the hole, including the larvae, will die. The dust will also remain in the galleries for a while, allowing it to eliminate the insects completely. After filling the hole with dust, seal off the entrance using a spray sealer to keep other bees from moving into the gallery.

When applying dust pesticides, you need to wear protective gear. If you use this solution, prepare a foam sealant in advance to help you seal the hole immediately after applying the dust.

Use Loud Noise and Vibration

Carpenter bees leave active nests when loud music is played nearby. You may even consider installing outdoor speakers near the infested areas. However, you need to remember to turn them on regularly.

The bees are sensitive to loud sounds, and the constant noise and vibrations will force them to leave. If you cannot access a music system, consider heavy wind chimes instead.

Getting rid of carpenter bees using loud noise and vibrations is one of the safest and least disruptive methods since it does involve using harmful chemicals. This method leaves your property open to the bee’s return. However, you can prevent this using sealant. You can also set a trap to capture the adult bees hovering around.

Nevertheless, before using this approach, inform any nearby neighbors since loud music can be a nuisance.

Use Natural Repellents

How to Get Rid of Carpenter Bees: Best Methods to Try

Natural repellents are a good option for getting rid of carpenter bees without killing them. One of the best examples is a citrus solution. You can easily make one by boiling lemon or orange fruit peels in water for some time. After boiling the peels, let the solution cool and pour it into a spray bottle. Alternatively, you can buy ready-made citrus spray at the store and use it directly on the bee holes. Carpenter bees are repulsed by the citrus scent and will therefore stay away from your home.

Another natural repellent is almond oil. Just like citrus, almond has a strong smell that carpenter bees dislike. Before applying almond oil, mix it with water to dilute the solution.

Other natural repellents include:

  • Cucumber peels
  • Garlic powder
  • Citronella candles

Besides applying the natural repellents on the affected area or the bee nests, you can apply them around other surfaces outside your home. This way, you can keep them from boring fresh holes in the woodwork. Natural repellents can also help you get rid of carpenter bees in the ground.

Vacuum Them Away

A vacuum cleaner can also be an effective method for getting rid of carpenter bees on your porch. For this method to work, your vacuum should be powerful and have a thin nozzle.

Vacuuming works better when the holes are new and not very deep. Notably, vacuuming may not work on larvae, but you still need to get rid of them before they develop into adults. That’s why you seal the holes.

If you decide to use a vacuum, do it during evening hours when most bees are in their nests. Wet vacuums are typically more powerful and raise your chances of sorting out the issue quickly.

Hit Them with a Racket

How to Get Rid of Carpenter Bees: Best Methods to Try

Additionally, if you may notice carpenter bees flying around your home, you can easily get rid of these flying insects by hitting them with a tennis ball or a badminton racket. Their large size makes this possible. Once you hit them and they fall to the ground, stomp on them to ensure their demise. You can also opt for electric rackets that kill the bees immediately.

Hitting carpenter bees with a tennis racket is one of the easiest and most effective methods to eliminate these pesky bugs and prevent them from burrowing into the wood surfaces in your home.

Nevertheless, getting rid of carpenter bees using a racket is not the best option since you can only kill the bees that come too close. Also notable is that the female carpenter bees don’t make it a habit to come near people.

Use Diatomaceous Earth

Some people use diatomaceous earth to get rid of carpenter bees from their homes. Diatomaceous earth is simply powder made from grinding fossilized algae. The powder cuts into the bodies of insects and absorbs the fats and oils on their exoskeletons. This leads to their dehydration and eventual death.

For this method to become effective, sprinkle the diatomaceous earth on the surfaces near the infested areas. You may also sprinkle the powder directly into the bee’s nests and seal them in. After about three days, they will start dying.

Diatomaceous earth can irritate your skin and is especially scathing on body parts like the eyes and nose, so you need to put on protective clothing.

Use A Bee Catcher

Another effective method to help you get rid of carpenter bees is using a catcher. This method is the best choice if you’ve spotted a lot of bees near your house but haven’t found a hive. Moreover, the catcher method works best in instances where bees are drawn to the flowers on your property.

There are various kinds of bee catchers on the market today, including kill and no-kill models. You can also consider making a DIY catcher yourself and saving some money.

How to Get Rid of Carpenter Bees: Best Methods to Try

To make a carpenter bee catcher, you need maple syrup, water, a 2-liter soda bottle, and a stapler. First, cut off the top part of the soda bottle. Mix the maple syrup with water and pour just enough into the bottle to cover the bottom. Flip the head upside down and replace it on the bottle using staples to hold the sides together. The bees should have no problem getting in but getting back out is the impossible part.

How to Prevent Carpenter Bee Infestation

The best way to deal with carpenter bee infestation is by taking precautionary measures before it becomes a big deal. However, the effectiveness of your methods depends on how early you employ them. Below are some of the best methods you can use to prevent carpenter bees from infesting your home.

Plug Up Holes

As seen earlier, carpenter bees like boring holes on wooden surfaces to create a habitat. Once you kill the insects, you need to seal the holes to prevent them from coming back.

There are various ways to seal carpenter bee holes. The most prevalent method is applying wood putty to the hole. After applying the putty, repaint the surface to improve aesthetics. Wood putty is only effective when you want to keep adult bees away from the holes. However, it won’t stop the larvae from drilling their way out as spring approaches.

Besides wood putty, some people prefer using caulk. This method can be effective since it prevents adult bees from entering the hole and suffocates the larvae, preventing the bees from multiplying. Although this solution is better, it has its downsides. For instance, once the caulk dries, it may leave some spaces that allow the adult bees to enter.

If you don’t find the wood putty or caulk, you can use steel wool. You can also buy stainless steel blocker kits to seal the holes.

Paint or Varnish Exposed Wood Surfaces

How to Get Rid of Carpenter Bees: Best Methods to Try

Although carpenter bees can attack virtually any type of wood, they like boring holes on uncovered wood surfaces. Therefore, if you want to prevent these insects from causing damage in your home, consider painting them.

Before taking on the task of painting, fill any cracks or nail holes with wood putty or caulk. Alternatively, you can stain your woods with varnish. However, stained wood is less effective than painting.

Replace Damaged Wood

After killing adult carpenter bees, the next step should be replacing the wooden surfaces. You don’t want them breaking and injuring you. Furthermore, even if you tried your best to eliminate the insects, the damaged wood may still be home to maturing larvae and pupa that’ll grow to cause you more problems.

To deal with this issue completely, remove the damaged wooden surfaces and replace them. Discard the damaged pieces of wood far from your home. You can also consider burning them.

Use Fine Mesh Screens

How to Get Rid of Carpenter Bees: Best Methods to Try

You can use fine mesh screens to keep the carpenter bees from your wooden surfaces. One way to do this is placing them between the rake boards and vinyl siding around the roof. You can also cover some pieces of outdoor furniture with the same.

When Is It Time to Call a Professional?

All the DIY techniques of getting rid of carpenter bees in your home discussed above can help you deal with the issue. However, some of the methods are dangerous and entail coming into contact with toxic chemicals. If you accidentally spill the chemicals on your skin, you may experience an allergic reaction and other serious injuries. Therefore, you may want to defer handling these chemicals to someone else. Moreover, you need to have the necessary protective clothing to protect yourself.

The carpenter bees are likely to sting you if you tamper with their habitat. The worst part is that some DIY methods don’t completely get rid of the carpenter bees, and they may come back after some time.

For these reasons, you may need to call an exterminator. These professionals have the necessary equipment to help them get rid of the carpenter bees for good. They also have the skills and knowledge needed to help them get rid of these insects once and for all.

Furthermore, they’re more adept at inspecting for damage and have the necessary protective gear to protect them from chemical accidents or bee stings.

How to Treat Bee and Wasp Stings?

Provoking wasps or bees comes with the risk of being stung. Bees have a barbed stinger connected to a venom sac. A wasp’s stinger may look similar to a bee’s to the naked eye but is actually smoother. When these insects sting you, the venom sac contracts, releasing poison which can cause complications.

Common Symptoms of Bee and Wasp Stings

How to Get Rid of Carpenter Bees: Best Methods to Try

These are the common side effects of bee and wasp stings.

  • Intense burning pain at the sting location that lasts a few seconds
  • A swollen and itchy red mark
  • Fever, rash, headache, and nausea
  • Pain and swelling in the joints
  • Swelling of the entire extremity that may last for a few days

In extreme cases, bee and wasp stings may cause a severe allergic reaction. If you fail to seek urgent medical attention, you may experience anaphylactic shock.


Often, bee and wasp stings can be taken care of with home treatment, especially if a person does not exhibit any severe allergic reactions. Common ways to treat bee and wasp stings at home include:

Remove the Stinger

How to Get Rid of Carpenter Bees: Best Methods to Try

When a bee stings you, they leave a stinger on your body. This stinger contains venom, and the first thing you need to do is remove it. When removing the stinger, you need to be extra careful. The best method to remove the stinger is by scrapping it with your fingernails, credit card, or a piece of gauze. Avoid using tweezers since they can squeeze the stinger, making it release more venom into your skin. As a result, you may experience severe allergic reactions.

Wasps, on the other hand, don’t leave stingers, so you may need to skip this step altogether.

Apply Ice on the Swelling

Another way to treat bee and wasp stings is by applying ice to the swollen area. Ice helps reduce blood flow to the swollen region, helping the swelling to go down and reducing the pain.

When using ice, avoid applying it directly to your skin. Otherwise, it may burn your skin leading to more pain. Instead, you wrap the ice in a towel or put it in a bag before compressing it on your skin. Also, don’t apply ice to your skin for a prolonged period.

Experts recommend using ice to reduce swelling on your skin for a maximum of 20 minutes. If the swelling won’t go down even after that, you’ll need to seek immediate medical attention. Also, if the swelling spreads to other body parts like the face and neck, go to the hospital immediately.

Take Antihistamine

How to Get Rid of Carpenter Bees: Best Methods to Try

Stings, in general, can be quite painful, especially in the region where the insects left the stinger. Stings from these insects can also make the area itchy or swollen.

To relieve these symptoms, consider taking oral antihistamines like Zyrtec and Benadryl. These drugs can help calm your body’s immune system after an allergic reaction. When taking these drugs, follow the doctor’s instructions to ensure effectiveness. Following the doctor’s instructions also helps you avoid other side effects like drowsiness or stomach irritation.

Take Painkillers  

Considering how painful bee and wasp stings are, you should consider taking over-the-counter painkillers such as ibuprofen. These drugs will relieve your pain, allowing you to continue with your daily routine.

Wash the Sting Spot with Water and Soap

How to Get Rid of Carpenter Bees: Best Methods to Try

After removing the stinger from your skin, consider washing the sting area using water and soap. Washing this region helps to get rid of the remaining venom, preventing it from diffusing into your bloodstream. Additionally, washing this area reduces the chances of getting a bacterial infection. Afterward, apply hydrocortisone cream to the affected area to help reduce itching, redness, and swelling.

Get a Tetanus Booster

Bee and wasp stings can pierce your skin, exposing your body to various infections. For instance, the open wound may allow tetanus bacteria to enter your body and exacerbate your condition. Therefore, it is essential for people to go for regular tetanus shots to keep them prepared for such situations.

According to professionals, you should go for tetanus shots every ten years. If it’s been a while since your last tetanus shot, consider getting it within a few days to reduce the chances of complications.

Use Essential Oils and Plant Extracts

You can treat both bee and wasp stings using essential oils and plant extracts. Common plant extracts and essential oils you can use include:

  • Lavender– Lavender essential oil has anti-inflammatory properties that help reduce swelling in your skin. Before using the oil, mix it with a carrier oil like olive or coconut oil to dilute it. Apply sparingly to the sting area.How to Get Rid of Carpenter Bees: Best Methods to Try
  • Aloe vera– People use aloe vera for various functions, including soothing the skin. Since bee and wasp stings irritate your skin, you can apply aloe vera to the sting location to reduce the effects. You can get an aloe vera solution in most stores. However, if you have the plant in your compound, you can produce your own gel. Just cut the leaf, squeeze the gel into a bottle, and apply it to the affected skin. Carefully store the gel in a cool place for future use.
  • Tea tree oil– Tea tree oil is a natural antiseptic produced from a tea tree. Often people use this oil to ease pain from bee stings. Tea tree oil can also help prevent the affected area from becoming infected. When using tea tree to treat bee or wasp stings, mix it with essential oils and apply it sparingly to the affected region.
  • Witch hazel– Witch hazel is considered a natural antiseptic and astringent. Most people use it to treat bee and wasp stings since it can prevent further infection. Additionally, this solution can reduce swelling and pain in the affected area. Unlike other essential oils or plant extracts, witch hazel doesn’t require to be mixed with carrier oils. Once you get the liquid, apply it directly to the sting area.
  • Calendula– Calendula comes in the form of a cream. This antiseptic can be used to reduce irritation on your skin and heal wounds. When you apply the cream to your skin, wrap it with a bandage to allow it to keep the cells active. Moreover, covering this region with a bandage protects it from germs that may cause infection.

How to Get Rid of Carpenter Bees: Best Methods to Try


How to kill carpenter bees with WD40?

Getting rid of carpenter bees from your home using WD40 is quite simple. Start by spraying WD40 on the untreated wood in your home, especially just before spring, to prevent these insects from building a nest in your home. If the bees already have a nest in your home, you can spray it directly into the holes. Spraying WD40 directly into the carpenter bee holes is easy since it comes with a straw. You can repeat the same process for two to three days to ensure the death of the adult bees and larvae. After that, cover the hole with caulk or wood putty and paint the wood. Killing carpenter bees with WD40 is not a complicated process. However, you need to exercise a lot of precaution since the spray can be toxic. Be sure to follow the manufacturer’s instructions and wear the necessary protective clothing.

How long do carpenter bees stay around?

Carpenter bees are commonly seen in April and May when they emerge to mate. During this period, the male carpenter bees hang around nest entrances, searching for receptive females. After the females lay eggs, they will hatch into larvae and grow into adults. The newly hatched carpenter bees come out of their nests between august and September to feed and pollinate flowers. When winter sets in, the young carpenter bees will go back to their nest to hibernate. The lifespan of male carpenter bees is about one year, and they usually die immediately after mating. Conversely, females can live for up to three years and usually die after laying eggs.

How to get rid of carpenter bees with paper bags?

The paper bag trick is a simple DIY trick that can help you get rid of carpenter bees. The trick involves blowing some air into a brown paper bag. Once it becomes balloon-shaped, tie the top with a string to prevent the air from escaping. You can also include old newspapers in the bag to make it bulge. The main aim of using this trick is to mimic a wasp nest. Wasps are carpenter bees’ natural predators, so they cannot stay in the same place. To make the bag look like a real wasp nest, add some creases on the brown bag. This method should remain effective as long as the bag stays spherical and positioned correctly.

How to get rid of carpenter bees with pine soil?

Pine sol is an extremely effective method when it comes to killing carpenter bees. There are two main ways you can use this solution. First, dilute it with water, pour it into a spray bottle, and carefully spray it on the untreated wood surfaces. If the insects have already created a hole, spray the solution directly into the hole. Another way that you can use pine sol to get rid of carpenter bees is by pouring the solution into a milk jug and hanging it in a slanted position near the infested area like the top of your fence or porch. The sweet pine sol smell will attract the carpenter bees, and they will die when they come into contact with it.
