If you’re not averse to using insecticides, then you’ll find several in any of the home repair big-box stores, that specifically target hornets and wasps. Just make sure you cover yourself well from head to toe, eye protection, etc. the full deal (with as many layers as you can. you really don’t want to get stung).

Most of these sprays work from afar (about 5-10 feet away), so you won’t have to get too close to the nest. However, do remember to spray it only at night time, as that’s when the hornets are mostly inactive (a.k.a taking a few winks).

Lastly and most importantly, don’t forget to read the directions on the can!

How to Get Wasps Out of a Hole in a Tree

Wasps are less active at night, making it easier to remove them.

Physical or chemical controls can remove wasps nesting inside a tree. Using the right techniques, you can completely remove the nest without suffering stings or bites. Eliminating wasps using a pesticide spray has several advantages over physical removal, such as spraying from the ground rather than coming into close contact with the nest. Wasp nests are much smaller and easier to remove early in the summer.

Physical Control

Familiarize yourself with the ground around the tree and the location of the hole during the day. Wait until evening when the temperature has fallen to 60 degrees Fahrenheit or less. Wear thick clothing that covers any exposed skin.

Place your ladder so that you can reach the inside of the hole and carefully climb up to the entrance. Quickly place your plastic bag over the nest so that any wasps exiting the nest are trapped inside the bag. Dislodge the nest from the tree so that it falls into the plastic bag and the quickly tie the end so that no wasps can escape.

Climb back down the ladder with your bag and leave the bag in a location that receives full exposure to sunlight. Leave the bag exposed to the sun for two to three days or until the wasps are dead, then dispose of them in the trash.

Chemical Control

Purchase a wasp killer with an extended spray that can reach up to 20 feet. Look for wasp killers containing the chemical peremethrin, tetramethrin or another form of pyrethrin, nerve toxins designed to paralyze wasps, preventing them from attacking you.

Examine the tree in the early morning and familiarize yourself with the area when the outside air temperature is below 60 F. Locate any holes in the tree around the nest that could harbor wasps and mark them using whitewash or another paint suitable for use on trees.

Wait until evening when the temperature is below 60 F and there is little wind. Wear thick clothing that completely covers your arms, legs and torso. Use gloves to protect your hands from stings and chemical spray. Wear a face mask and safety goggles for further protection.

Position your ladder opposite the main entrance to the hole in the tree where the wasps are nesting if you can not reach the nest from the ground. Make sure that you are positioned upwind from the hole in the tree and that you are close enough for the pesticide spray to reach the nest.

Shine a flashlight on the hole to spot any wasps exiting the nest and direct your pesticide spray into the nest, but avoid shining your flashlight directly on to the nest since light can disturb the insects. Adjust your aim to directly strike any wasps that exit the hole. Make sure your spray reaches the nest and covers the areas of the tree adjacent to the hole.

Reposition your ladder to face the other holes in the tree that you marked earlier. Spray pesticide into the holes and on to the surrounding wood. If your first treatment of pesticide agitated any of the wasps, leave the area until they have subsided before spraying any remaining holes.

How to Get Rid of a Hornets Nest

Hornets and wasps have an important role in our environment. They prey on other insects, helping to keep pest populations under control. For the most part, they do their job while we go about ours. But sometimes we cross paths with these stinging insects and they become aggressive and dangerous.

Hornets create nests to have a place to lay eggs. They often find sheltered areas such as trees, rafters, or roof eaves to call home. The nest will look like it is constructed out of paper or mud and is often shaped like a cone or just a big lump. If hornets have taken up residence too close to your home, you may need to eliminate their nest in order to keep you and your family safe. Here’s how to take the sting out this process.

Removing the Nest

Before you take on the task of removing a hornet’s nest, it’s important to protect yourself by wearing the proper clothing. You should wear thick clothes that cover all of you, leaving no skin exposed. There should be elastic around the sleeves and pant leg bottoms to prevent hornets from flying underneath the clothing. Add a protective mask, goggles, and heavy gloves, and you’re ready to go.

Hornets return to their nests in the evening and become less active, so this is the best time to kill the majority of the colony. Use an insecticide specifically designed to kill hornets and be certain that the spray can reach from a distance of at least 15 feet, so you can be out of harm’s way. An insecticide spray should kill the pests on contact.

After spraying, wait a bit to make sure all the hornets are dead. Then you’ll need to remove and destroy the nest so that other hornet colonies can’t make a home there. Put the nest in a heavy duty trash bag to dispose of it, and then clean the area where the nest had been with soap and water.

When It’s Time for Professional Help

If a hornet’s nest is too big or in a hard-to-reach place, it is time to call in a professional. A good rule of thumb is that if the nest is smaller than a tennis ball, it may be safe to remove on your own. The process of removing these stinging insects is dangerous, even if you are not allergic. Definitely call in a professional if you are concerned about safety or uncertain about allergies.

Taking on the task of removing a hornet’s nest may be more dangerous than you think. If you find a nest too close to your home, call Green Pest Solutions and they will remove it for you, plus provide you with ways to prevent these pests from getting too close for comfort in the future.

We’ve just noticed a large (2.5 ft?) hornets’ nest hanging in a tree in our yard. Hornets are flying in and out of it. Neighborhood kids play in our yard a lot, shoot things up in the air. When would be the best time to get the hornets’ nest out of the tree? and how best to do it?

If you have just noticed the nest and the children have been playing there all summer, you need not take any action other than admonishing the children to avoid throwing things at the nest. Only the queen(s) will survive the winter and she (or they) will overwinter in a sheltered location and establish a new nest and a new colony next spring. After the first hard frost, the nest will be empty and will never be re-occupied. Some people collect vacant hornet nests. If you would like to educate the children further, you could arrange for someone to retrieve the nest this winter and carefully cut it into two halves. The interior is intricately beautiful.
Assuming it is a European hornet nest, these insects are excellent predators of other insects. They are unusual in that they will fly and hunt both day and night. They are especially attracted to porch lights where they prey on moths. They are not aggressive unless disturbed. So, if the nest is high in the tree, simply wait till frost. If you consider it to be a serious threat, we can help you find a beekeeper who will be willing to remove the nest.

First of all, thank you so much! What a thorough and clear and interesting answer! The nest is pretty high up and though I’d love to take it down and dissect it, I’m not sure I’ll be able to. Are you sure that if I just leave it there, the hornets won’t move back in next spring?

The kids have already been warned about aiming balls and rockets away from the nest.

It looks very much like the picture below — is that a European hornets’ nest? I worry because I’ve read about very aggressive hornets. And maybe about some aggressive hornets remaining in the nest after the queen dies so that when (if) we take it down, somebody gets stung.

My tree is a wasp magnet, what can I do to get rid of them?

There is a small tree (about 2 meters tall, maybe a bit more) at the front of my house that has become a wasp magnet in the last few weeks. I have seen at least 2 kinds of wasps hanging in there, and there must be around 100 of them.

Is there a way to prevent this tree from attracting them without cutting it down?

These are some of the wasps that have been hanging around, I took the pictures after using some anti-wasp spray:

In case it is relevant, I live in Quebec, Canada, and winter is comming.

Wasps are very territorial. If you place a fake wasps nest, they will stay away from it. Paper and wire «wasps nests» can usually be found cheap anywhere camping equipment is sold, or you could fashion your own from a waterproof material.

I’ve thought of something that might be causing the trouble — check the tree, if you can find a time when it’s not got too many wasps on it, inspecting the needles closely for signs of aphid infestation. They’re often difficult to see, so you might need a magnifying glass. If there’s an infestastion of aphids on the tree, they produce honeydew, and wasps like the honeydew, so that might be why they’re on the tree all the time — they’re actually after the honeydew.

I used 2 traps earlier this summer with great success, i purchased from my local hardware store for $4 each. they were the type where you cut some plastic flap off of the top and pull the mounting hardware bit out, then you put water in it, which dissolves a pouch of wasp bait.

they are supposed to be good for 6-8 weeks, probably more like 3-4, but they killed many many hundreds of wasps and had a very wasp free mid-summer, which is usually the worst part.

will be doing the same thing next year. I have tried re-usable traps in the past with little success and less desire to clean an re-use them.

Hornets primarily build their nests in far reaching locations, like rooftops or high tree branches. Although their nests are very attractive, no one enjoys having it around their yard! This is because like wasps, bees, and yellow jackets, hornets are a nuisance and can be dangerous for you and your family. You can get rid of the nest from the tree if you are cautious, and following these steps will help you avoid calling in a professional exterminator.

  1. Ensure you are not allergic to the sting of a hornet. You must tae an allergic test to find out, and if the result is positive, it is best to call a exterminator to remove the nest.
  1. Locate the area of the hornet nest around the tree area. Check for other nests under the tree to eradicate all.

  1. Wear protective gear and equipment. This will include a bee hat, long sleeved shirt, eye wear, gloves, and coveralls.
  1. Get a large and strong plastic bag that is not ripped. Place this bag directly under the nest, so that when it falls, the bag catches it.
  1. Treat the hornet nest at night so that all the workers and queen are present in the nest. Also, these hornets tend to be less aggressive at night, and the effect of the pesticide is stronger at this time, killing off most of the hornets.
  1. Spray into the hornet nest opening, which will be at the bottom of the nest. Do not break the paper envelop nest during the treatment.
  1. Do not stand below the nest, as it increases the risk of being stung.
  1. Use a hedge trimmer with a long handle to cut the branch of the tree.
  1. Tie the nest in the bag and dispose it or burn it straight away.

How to Kill Bees in a Tree

By: Kimberly Sharpe

Wild colonies of honey bees commonly nest in old, hollow or rotted-out trees. The bees can easily become a nuisance when spring arrives. The bees will congregate around swimming pools and bird feeders where people may commonly get stung. Many people are allergic to bee stings and can even experience a life-threatening reaction.

Destroy honey bee nests in the spring or early summer. Spray the hive at night when the bees are in the hive and they are the least active. If the nighttime temperature dips below 50 degrees Fahrenheit, bees rarely will fly out of the hive during spraying.

Wear long sleeves, long pants, gloves and a hat while killing a hive. If you have access to a beekeepers bonnet and gloves, use them to prevent painful stings.

Spray the hive using a bee-killing aerosol spray. Follow the directions on the label for application. Focus on the hive’s main entrance when spraying. Thoroughly saturate the area.

Watch the hive for three days to make sure there is no activity. If you see bees leaving or returning to the hive during the day, repeat the application until you can go three days without observing any activity.

Destroy the hive once all bees are dead. If the hive is located in a tree cavity, scoop out the dead bees, hive and honeycomb. Thoroughly wash the area of all honey using dish detergent and water. If the hive is not removed or thoroughly cleaned of all honeycomb and honey, ants and beetles may invade the tree. The only way to make sure you prevent reinfestation is to cut down the tree.

Never attempt to kill a hive of bees if you suspect you are allergic or suffer from a known bee allergy. In that case, rely on a professional.

How to Get Rid of Carpenter Bees

Belonging to the genus Xylocopa, carpenter bees are large bees having a size of around 3/4 to 1 inch. There are small carpenter bees too that belong to the Ceratinini family. Now, why are they called carpenter bees? Because they build their nests in wood. This can be a dead wood, bamboo or the structural timbers of your house and even your wooden furniture, especially the garden furniture. In this, we are going to find how to get rid of Carpenter Bees.

How to identify Carpenter Bees?

Looking once at a carpenter bee can make you think as if it is a bumble bee. Here are some pointers that will help you identify the carpenter bees, your first step to getting rid of carpenter bees. These points also contain certain facts that will help you distinguish between carpenter bees and bumble bees.

  • Carpenter bees are large in size, about an inch long (bumble bees are 1/2 to 1 inch long)
  • These bees have black shiny body mostly having yellow colored hair on the thorax. Sometimes the color of hair can be white or orange too. (Bumblebees have black and yellow or black and orange body. Of course, the two bees are quite similar in appearance, why else they would be confused with each other)
  • Most of the top part of the abdomen of carpenter bees is hairless and is shiny black in color. (Bumblebees have abdomen fully covered with hair, mostly yellow hair. At last, there’s some difference in both the bees to help you identify carpenter bees!)
  • If you see such large bees hovering around the eaves of your house or drilling in wood, be assured, these are carpenter bees. (Bumblebees, on the other hand, can be seen traveling between their underground nest and the flowers from where they obtain food. Yes, there nests are under the ground.)
  • You can also identify male and female carpenter bees by looking at their heads. This is important because then you will know if the bee is capable of stinging or not because male carpenter bee doesn’t sting. The female bee is able to sting but doesn’t do this unless provoked extremely. You will, of course, provoke her extremely by trying to demolish its nest. So, to distinguish between male and female carpenter bee, look at its head. Female bees will have blackheads, and male bees will have white marks on their heads.

How to find Carpenter Bees’ Nest

Once you have identified the carpenter bees, you now know that there is a nest of these bees in or around your house. The task now is t find the nest of the carpenter bees. But how to do this?

For this, you need to

  • Locate the place where male carpenter bees hover around. Female bee bores holes into rough and unfinished wood to make her nest so that she can lay eggs there. These holes are the nest of carpenter bees and these can be shallow or deep- as shallow as five to six inches and as deep as four feet. This happens in Spring season when adult bees mate and start cleaning and enlarging the old tunnels. They may also excavate new ones as brood chambers for their young.
  • If you see male carpenter bees (you know how to identify them), hovering around some wooden structure, check the ground there or any other horizontal surface beneath that place.
  • If you see something like coarse sawdust, the nest is there only, just above the frass. Frass is the sawdust that falls off from the wood in which the hole has been drilled.

When you search for the nest, you don’t have to worry about the male bees that will intimidate you by flying at you and buzzing around your head. They can’t sting. However, be careful about the female bees, they can sting.

Once you have located the carpenter bee’s nest, you can take required steps to get rid of them. But before knowing how to get rid of carpenter bees and their nests, let’s know why it is essential to remove the nest? After all, it is just a hole of about half an inch diameter!

Why Carpenter Bees’ Nest removal is essential?

A hole made by a bee in a wood is just a slight damage to the wood. However, think about the time and again when carpenter bees work on old tunnels to make brood chambers for their young ones.

The young adult bees hibernate in winters inside the tunnels in the wood. Every year, after the adult bees wake up from their hibernation, they mate in the spring season. Then they start cleaning the tunnel. They make it large. They excavate new tunnels to create brood chambers. Each such chamber has ‘bee bread’ which is a mixture of pollen and regurgitated nectar. This is the food for the larvae. The female bee lays her egg on the food and seals off each of the chamber. These eggs then develop into adult bees and repeat the life cycle.

  • Every year, the brood chambers keep on expanding. This also expands the tunnel through branching activities. This ultimately causes considerable damage to the structure.
  • The bees also defecate on the wall or other surfaces directly below the opening of the tunnels. This causes stains.

How to get rid of Carpenter Bees?

Once you have found out where the nest of carpenter bees is, it becomes easier to remove it. Just that you need to do just the right things to get rid of these bees.

1. Use Insecticidal Dust

If you have active carpenter bees in or around your home, the best thing would be to use insecticidal dust. This way, you protect your wooden structure from harmful liquid chemicals that may get absorbed into the porous wood and at the same time, you ensure that carpenter bees come in contact with this dust and get eliminated.

  • Insecticidal dust
  • Duster
  • Protective clothing like gloves, goggles, respirator, dust mask etc. and wasp or hornet spray if doing the task during daytime
  • Flashlight and red cellophane if working at night
  • Preferably, do this during night time so that you may avoid stings of female carpenter bees. If so, cut a piece of red cellophane and stick it to the flashlight to make the light red. Bees are not able to see red light but you will easily see the opening of the nest.
  • If working during the daytime, wear all the possible protective clothing and accessories. Keep a wasp spray handy so that you can use it on any bees that fly around you to defend their nest. Remember, female bees can sting.
  • Using the duster, apply insecticidal dust directly into nest openings of the carpenter bees that you have found out.
  • Duster puffs the dust up into the tunnel made by carpenter bees and also coat its sides.
  • That’s all for now
  • Wash the clothes that you have been wearing immediately and don’t mix with another household laundry
  • Take shower to avoid any risk due to insecticidal dust that might have contacted your skin or body.

The next step involves plugging the holes that you have treated with insecticidal dust but that needs to be done later because you want all the bees inside to come in contact with the dust. When they emerge out of the hole and go inside, they will spread the dust inside the tunnel.

2. Plug the Openings of the Nest of Carpenter Bees

This needs to be done, preferably, in the fall, after you have treated the nest openings with insecticidal dust at least thrice – in the spring, in mid-summer and in early fall. This ensures that you eliminate adult bees, newly matured bees and all the other bees in hibernation during winters.

  • Wood putty or wooden dowels
  • Paint or Varnish
  • Fill the holes, the openings of the carpenter bees’ nests, using wood putty or wood dowels
  • After this, either varnish or paint the entire wood surface.

Precaution- pesticides are poisonous and thus need to be handled carefully. If that’s not the way you intend to get rid of carpenter bees, try the following remedies for carpenter bees elimination.

Home Remedies to get rid of Carpenter Bees

If insecticidal dust is not what you were looking for when thinking of getting rid of these carpenter bees, you might be happy to use the following home remedies to get rid of carpenter bees.

Use your vacuum cleaner

  • Take the smallest nozzle of your vacuum cleaner, and get set to clean the carpenter bees.
  • Place the vacuum cleaner nozzle over the openings of tunnels made by the bees in the wood.
  • Now vacuum up the bees. It’s that easy. However, try to do this in the evening when all the bees have returned to the nest. Better, if you can do it during the night.

3. Spray Petrol over the Nest of Carpenter Bees

Before using petrol, know that it is a pesticide even if natural. Also, petrol is highly flammable and wooden surface drenched with petrol is not a very good sign. If you can handle petrol and wood safely, then only think about this remedy otherwise there are many more remedies for carpenter bees.

  • Protective clothing like goggles, gloves, respirator etc.
  • Petrol (or diesel)
  • Spray bottle or a bottle with a small pointed nozzle
  • Wear all your protective gear
  • Fill only a little amount of petrol in the spray bottle or the one with a nozzle
  • Spray the petrol in the tunnels of carpenter bees. If using nozzle bottle, place the nozzle inside the hole and pour the petrol into the tunnel

Don’t use this bottle for anything else. If you can discard the bottle, that’s the best option. If not, label it as ‘Petrol Only’. Don’t use it to spray water or other liquids over plants etc.

4. Make Noise near Carpenter Bees Nests

This seems insane! However, it’s not that a useless activity to do. Carpenter bees are extremely sensitive to noise or should it be said like this, they are extremely sensitive to the vibrations made by loud noises.

Soundbox or Boombox

  • Place the sound box or the boom box as close to the nest of carpenter bees as you can
  • Now play it
  • The bees will be forced to get out of their nest

You can’t get easier remedy than this to get rid of carpenter bees!

5. Dust the Nest with Boric Acid

Boric acid is a poison and thus it can kill the carpenter bees. However, be careful while handling it, if using. Always wear protective clothing and mask to avoid breathing the air that might have particles of boric acid when sprayed for carpenter bees.

  • Boric acid comes in powder form so use a duster to apply it over the openings of the nests
  • Wear protective clothing before doing this

If you don’t want to use boric acid, use the non-toxic diatomaceous earth for carpenter bees

6. Use Diatomaceous Earth for Carpenter Bees

Diatomaceous Earth is a soft, crumbly, porous sedimentary soil like powder formed from the fossil remains of diatoms, a type of algae. It is a natural pesticide. The sharp edges of microscopic diatoms present in the diatomaceous earth shred the outer shell of bees and other insects and kill them by drying them out. Use the food grade diatomaceous earth and not the one used for pool filtration systems.

  • Diatomaceous Earth
  • Turkey baster (or a needleless syringe)
  • Gloves
  • Wood putty
  • Wear the gloves
  • Fill the turkey baster with diatomaceous earth
  • Now place its nozzle type of front part over the hole of the nest of carpenter bees
  • Inject the diatomaceous earth into the tunnel
  • Plug the holes with wood putty
  • Throw away the gloves and a turkey baster. Don’t use them for any other purpose

7. Spray Aerosol Carburetor Cleaner

Yes, you might wonder about this remedy but aerosol carburettor cleaners can effectively exterminate carpenter bees.

  • Aerosol carburettor cleaner
  • Protective clothing
  • Wear the protective clothing- gloves, mask, goggles etc.
  • Now take the can of the aerosol carburettor cleaner and pull out its extension tube
  • Place this tube inside the opening of the tunnel of carpenter bees’ nest
  • Spray the cleaner inside the nest
  • This spray will kill almost all the bees inside the tunnel
  • It will also make the tunnel uninhabitable so that the new bees who look for old nests do not find it attractive enough to live in.

8. Make Citrus Spray get rid of Carpenter Bees

Probably the smell of citrus fruits etc. are not liked by the carpenter bees or it is possible that these citrus liquids contain some elements that effectively eliminate carpenter bees. Whatever the reason might be, citrus sprays are one of the very effective remedies for carpenter bees. You can either buy a citrus spray specifically made for repelling carpenter bees or make one at home.

  • Citrus fruit/ fruits such as orange, lemon, lime, grapefruit etc.
  • Water
  • Pot
  • Spray bottle, preferably with a narrow nozzle
  • Take one or many citrus fruits and cut them in pieces. In fact, you can eat the fruit and save their peels and rinds for the purpose.
  • Take the pot and fill it with water
  • Heat the water and add the rinds of the fruits
  • Let the water boil for the time till it remains half of its original quantity
  • Now put off the flame and wait for sometime so that the citrus water cools down a little
  • When the water is manageable hot, fill it in the spray bottle
  • Now spray this homemade citrus repellent spray inside the nests of the carpenter bees and get rid of them

9. Use Almond Oil to repel Carpenter Bees

Almond oil has passed all the test when it comes to naturally deter bees, including carpenter bees. Almond oil contains benzaldehyde which is known to repel bees. If you read the labels of certain commercially available bee repellents, you will find benzaldehyde as one of its active ingredients

  • Almond oil
  • Tea tree oil (optional)
  • Orange oil or other citrus oil (optional)
  • Water
  • Spray bottle
  • Take 1-2 tsp of almond oil and an equal quantity of any citrus oil, if using. You may also add few drops of tea tree oil to make the spray more effective
  • Pour them in the spray bottle
  • Fill the bottle with water
  • Shake it well to mix water and oils properly
  • Now spray this solution inside the nests of the carpenter bees

How to prevent Carpenter Bees from coming back and making nests in wood

Here are some tips for preventing carpenter bees. These are practical and really helpful tips.

  • The best policy is to first exterminate the bees using home remedies or with professional help and then plugging the holes so that these nests can’t be used in future by any carpenter bee.
  • Use wood putty or wooden dowels to plug the holes made by these bees.
  • Carpenter bees can easily carve and make holes in wood but cannot dig through steel wool. Plug the holes of bees with steel wool once they are exterminated.
  • Stain or paint outdoor wooden surfaces because these surfaces don’t attract carpenter bees. Untreated wood is mostly preferred by these bees to make their nests.
  • After sealing the holes, spray some citrus solution to further repel the bees
  • It is not enough to kill the adult bees only, you need to kill the larvae lying inside the tunnels. Use insecticidal dust for this. To know how to use and when to use this dust in order to kill all the bees and their larvae, read the earlier section of this article where insecticidal dust remedy for carpenter bees has been described.

Taking all these measures will definitely ensure that you get rid of carpenter bees completely.
