On tree trunks, on holes found on the outer side of a wall and even inside a wall cavity, in North America finding a papery nest in any of these places is not a surprise. The largest social wasp, the bald-faced hornet, can make a home anywhere ranging from garages to attics to crevices found on roofs. Where ever there is a tiny opening in your residence, you will encounter these common hornets flying around. If you find it hard to spot them, then look for a winged insect that has “white markings on its head and thorax.”
Goodbye, My Yellow Brick Wall!
Good many times bald faced hornets invade the walls of a house or building. It is during the start of spring and the end of winter hibernation that a lone queen hornet will search for a nice, cozy spot in your wall. She will make a minuscule structure and lay her eggs. Once the first brood of worker matures, they continue to expand the hornet colony and safeguard the queen. Through spring and into summer, the nest keeps on growing till autumn comes knocking. If this wasp colony is within a wall cavity, it can lead to disastrous results.
Kill Hornets Nest In Wall – When To Kiss And Say Goodbye
A bald faced hornet nest inside a wall is the toughest colony to eradicate, generally because they are hard to reach. To make this arduous task more manageable, here are some pointers on when to remove hornet colonies.
- Get rid of the nest as soon as you see it. If you are able to catch the settlement at the start of the year, then there is nothing better than it. It will be small with few wasps and that too very inactive.
- Eliminating the nest is easy at this point. Try to kill the queen. It gives the surety that another nest will not pop up again.
- Always treat or remove the colony at night when the hornet attendance is high, and they are sleepily lazy.
- If you need light to illuminate the way in the dark, use a torch that has a red or amber colored bulb. It will give you visibility, but not to the bald faced wasps that cannot see in the red light.
Hornet Nest In Wall Removal – Here Comes Goodbye
Though challenging and lengthy, getting rid of a hornet nest can be done by you with a pinch of bravery and a mountain of precautions. A few methods to do away with bald faced hornets from your home wall are talked about below.
This tactic should be employed when the nest is too big or wasp season is about to end. For example, late summer is when the population of bald faced hornets is highest and therefore the most hazardous. Wait for fall and with it lower temperatures. The hornets will die due to natural causes, and then you can remove the nest from the wall. You can also close all entrances to the nest so that wasps do not reuse it.
- Ensure that every single hornet has left the premises before sealing the wall.
- If you leave even one man behind, they will force their way out through some other section of the wall.
Fill a bucket with boiling water and then pour it directly over the nest hanging on the wall. The hot water will ruin the nest and kill some of the bald faced hornets. The appropriate method is to use multiple buckets of water with a gap of some hours between each. The ideal interval is one day. Bear in mind:
- The strategy will make the hornets hostile, and they may sting you.
- You will have to repeatedly apply boiling water to completely destroy the nest on the wall and then remove it.
Mix water with dish soap and then spray it on the bald faced hornet colony. The soap weighs down the wings and hinders their flying. In the end, the wasps die by drowning. If the nest is high up in the wall, use a “hose-end spray bottle” to directly squirt a stream of soapy water at the nest entrance. Keep spraying for 10 to 15 seconds. This method requires a repeated application for absolute elimination because the mixture has to touch every individual pest to kill it. To make the solution blend 1 liter of hot water with ¼ cup of dishwashing soap.
Spray apple cider vinegar on the wall where the nest is, into the colony and at the entry point to kill hornets. Wipe off vinegar after the nest is dead.
Black faced hornets abhor the smell of peppermint oil. Spray a mixture of water, oil and dish wasp inside the wall where the nest is to say goodbye to the pests. You can use this solution in conjunction with insecticides for better results.
Take a few mothballs and crush them using a hammer. Chuck the pieced up moth balls into the wall where the hornets reside.
Smoking out hornets from a wall cavity is a practical technique, but it requires courage to withstand the buzzing insects. Create a small, contained fire near the wall and make sure it builds up a lot of smoke.
Sprinkling the powder along the wall where the bald faced hornet nest resides works really well. You can even fill the crevasses of the wall by directly shooting the acid into them.
One part of the answer to how to get rid of hornets inside walls is traps. Baits should be used to lure away a few wasps from the nests. This will empty part of the wall colony and make it more manageable. Traps have to be appropriated along with other methods of nest removal. After the settlement is partly vacant thanks to the traps, seal any entry points you see and then get rid of the nest. To make a trap:
- Pick up any old bee trap.
- Add a piece of meat as bait in it. Hornets love protein-rich foods.
- Place the trap near the wall opening.
- The wasps will fly in to eat the meat but will not be able to fly out.
Choose any pesticide spray that is germane to hornets. Squirt it directly into any hole, gap or crack you see in the wall for about fifteen seconds. Vacate the location ASAP after application and let the spray work overnight. You might need to reapply the aerosol spray the next day if there are some wasps left alive. Always read the instruction given on the label and observe the hornet colony for activity from a distance.
A pesticide spray rarely reaches the core of the hornet nest. It is why insecticidal dust is the better option. Apply the dust liberally on the colony, wall and the opening. Do it either at night or before dawn breaks. Also, do not seal off the doorway to the nest. Give them the freedom to move to and fro. Each time they pass, the dust will coat their bodies; turn them into carriers who then contaminate other hornets too. Keep in mind:
- Wear protective clothing while treating the wall nest of hornets.
- Vacate the region after application.
- If all wasps are not dead after 24 to 48 hours, reapply the dust.
Hornet In Stone Wall Removal – A Late Goodbye
All the techniques explained till not to get rid of hornet nest in a wall assume that you are able to reach it and treat it. Next, we talk about a few tactics like hornets killing powder for wall made of stone. These are best employed when the colony is unobservable or too massive to handle by you alone.
If you are unable to locate the exact coordinates of the wasp nest, try to find an approximate section. You can do so by observing from where the hornets fly in and out. Once you have pinpointed all the exits and entries, seal them off using caulk. Using a sealant all over the wall before a pesticide is essential because:
- It will stop the wasps from escaping into any other part of the home and make a new nest.
- Running away from the nest and then returning after the chemical has become inactive.
Also use a hanging trap (as described earlier) to attract part of the wasp population away from the nest, before you use the powder.
How To Use A Pesticide Dust?
- Drill a hole in the wall close to where you think the nest is present. The hole can be quite small as long as it allows the applicator to enter the wall. Do not gauge a big gap.
- Push in the applicator portion of the pesticide inside the stone wall. Squeeze it to release the insecticide in a puff of air.
- An alternate method is to pry out wall boards and then scrape away the nest into a container which can be disposed of later. This strategy is not recommended because it can leave behind stray hornets and causes damage to the wall and the person.
- Therefore, after the pesticide has been sprinkled and the bald faced hornets are dead cover every tiny crack and crevice on the wall. Chances are the wasps will drill a new escape hole as you have closed off the original ones. Keep at hand a “see through bowl” to cover these new gaps and catch the escaping pests.
- Re-plastering the wall also ensure that no new queen hornet can use the unfilled nest to start her colony.
In some areas, there are local vector control deals available. They are professionals who help you identify insects or animals that carry diseases or are dangerous. Most times, they will only advice you on how to get rid of the vector, but in rare instances, they can even remove the bald faced hornet infestation from your home.
When you don’t have access to vector control and the hornet colony is in an inconvenient place, think about hiring an exterminator. Location like:
- Deep inside a stone wall
- Under a concrete floor
All these awkward regions are best handled by professionals who have years of experience removing bald faced hornet nests. You can even employ a pest control expert if you are allergic to the sting of black faced hornets. The method an expert will use is:
- Drill a tiny hole in the wall, window frame or doorway adjacent to the wasp nest.
- Pump a hornet killing chemical like insecticide through the hole.
How To Get Rid Of Hornet Nest In Wall & Be Safe
- Cover up with layers of clothes to prevent any stray stings before you treat a hornet nest. They can be painful if not allergic.
- Using a ladder to reach a wasp colony that is too high on the wall is not advised. Most people fall and injure themselves seriously.
- Have a pre-planned escape route which you can run through like wild hyenas chasing you if the bald faced hornets begin to swarm.
- If you have pets or children at home, take them out for the day when you use pesticides or insecticides.
- The timing is crucial to hornet control. The earlier in the year you treat a wasp nest, the more chances of success you have.
- Using aerosol sprays has some drawbacks. The bald faced hornets die and then begin to rot within the wall cavity. This increases moisture which leads to fungal development and mold.
- The hole of an active nest should not be plugged. The hornets will find another route and chew their way into your dwelling through a new hole.
When You Are Out Of Goodbyes
Let’s say you have utilized these techniques to get rid of a bald faced hornet nest inside a wall and have been successful. What do you do when you are done saying goodbye? You thwart any and all future infestations. Take these preventive steps:
- Remove food that is sugary or has meat from open areas, especially if you had a picnic or barbeque. They are invitations to wasps.
- All your garbage bins should be kept closed tightly.
- If you have fruits or berries growing in your backyard, pick them before they are ripe. Rotting fruit is like a magnet to bald faced hornets. Fallen fruits should be thrown away before wasps get to it. The ideal answer is not to plant any such trees.
- Any old, vacant nests you see near the dwelling should be taken down during winter months. There are high chances of a new colony rebuilding the nest if left as is.
- Shingles and sidings should be checked for any cracks and then sealed off.
- Fake nests are a great way to avert hornets. They are territorial creatures who never build their homes close to another wasp colony.
The Power Of Early Goodbye
A bald faced hornet colony inside a home wall has no advantage. Instead, they only drill tunnels and holes in the wall causing structural damage which is costly to repair. This makes identifying and removing a nest in a wall cavity fundamental. Thankfully, if you discover the hornet nest when it has just started managing them is relatively simple. So keep your eyes peeled and ears alert for any stray wings and weird noises this season!
