Wasps get inside your home’s walls through the wall voids to build nests.
Two types of wasps make nests inside the walls.
They’re yellow jackets and bald-faced hornets.
Both the wasps start to build nests from late spring. The process of building nests lasts till the summer months.
It’s by the end of summer, the number of wasps in your walls can reach one to two thousand.
But how to find a wasp nest in your wall?
You’ll find it out in this post.
But one important thing before we begin – “Don’t try any DIY methods to get rid of wasps and their nests.”
Wasps are quite aggressive. Their stings are excruciating too.
Wasp’s venom can give rise to severe allergic reactions, especially to babies and the elderly. Wasp’s sting can be life-threatening too.
So, once you’ve got the faintest of an idea of wasps and their nest’s presence in your home’s walls, contact a pest controller asap.
It’s safe for you and your family.
Without further ado, let’s get into it.
How To Find A Wasp Nest In Your Wall
To know the presence of wasps and their nests in your walls can be a tricky affair if you’re not that observant.
If you aren’t observant, it could be challenging to know wasps and their nests’ presence in the walls.
There are some apparent signs that many homeowners ignore.
Here are the signs of wasps in walls –
Holes In The Walls
Holes in the walls, at unlikely places, like too high or too low, are the entry points and exit points for the wasps.
These holes aren’t the ones that wasps create. These holes are pre-existing ones.
The holes may be small, to begin with. But wasps can dig a bit to make the holes wider for them to enter and exit.
You’ll also observe a few wasps entering and exiting from these holes.
That should alert you about the presence of wasps in the walls.
Wasps can eat through the walls to make space for the nests, which brings us to the next sign of wasps in walls.
Crackling Noise From The Wall
If there’s any sure-shot way to tell if wasps are in your walls, it’s the crackling sound.
The crackling sound is the sound of wasps eating through the wall’s bricks to make space for their nests.
Wasps build nests inside the wall voids on your home’s walls. They can get big and bulky if you don’t spot the nest at it’s early stages.
If left unchecked, wasp nests can end up weighing 8 pounds and beyond.
To accommodate a nest that big, the wasps need enough space.
And they create that space by relentlessly chewing the wall.
Wasps can quickly eat through the drywall.
It’s the chewing that produces a crackling sound.
But wasps aren’t nocturnal like many other bugs. They’re active during the day.
Hence the most probable time to come across the crackling noise from your walls is during the daytime.
So, keep your ears open during the daytime for any noise coming out of the wall.
Now we’re not talking about giant swarms like drywood termites.
But if you see some wasps in a group, buzzing around your home, then it’s an indication of wasp nests nearby.
Try to follow the wasps hovering around a shaded area or near a gap or crack on the wall.
You’ll reach the spot where they’ve built their nests.
But beware. If you reach that spot, don’t try to poke it or let your curiosity take over.
Wasps are territorial around their nests. They can sting you if you stay near the nest for long.
And it’s not just one sting. There may be thousands of wasps behind the wall that are waiting to attack.
Where Do Wasps Make Nests
It’s not only inside the walls that wasps make nests. There are other places too.
Wasps prefer to build their nests under shaded areas of your home that are a bit high from the ground.
So, porch roofs, roof eaves and rakes, sheds, garages, and even ground are common areas where wasps make nests.
During the fall months, wasps abandon their nests. And they breed by congregating on tall structures.
They don’t come back to the old nest. But wasps can build new nests in the same nesting location.
How To Prevent Wasps From Building Nests In Your Home And Property
Being proactive in preventing wasps from making nests in your home and property can save you from any inconvenience and stings.
So, here’s you can right now to prevent wasps from infesting your home –
- Caulk or fill-up all the cracks and gaps on your walls, especially on the outside walls. Use cement to seal the cracks, rather than a sealant.
- Use window screens or fly screens on your windows to prevent wasps from entering your home.
- Keep all the trash bins, both inside and outside of your home, free of the trash. Piled up trash attracts bugs, which in turn, attract the wasps. Wasps eat maggots and other bugs in the garbage.
- If you’ve wooden walls, check for gaps or places where the wooden beam is coming out. Fix it because that’s an entry point for wasps.
- If you’ve got a yard or a lush garden, keep it free of pests and bugs. They attract wasps.
What NOT To Do To Get Rid Of Wasps And Their Nests
Many people think that getting rid of wasps and their nests is as easy as getting rid of moths.
Well, it’s after a few hundreds of painful wasp stings they realize their mistake.
But not all wasps sting humans, like the horntail wasps.
It would be best if you never try to do that.
For your family’s safety, don’t even try to use any spray or powder that you might see on YouTube or elsewhere.
Yellow jackets build their nests at some distance inside the walls. The spray will not reach the nest.
Getting rid of wasps and their nests from your walls and your property need professional hands.
Pest control professionals need to cut off a portion of the wall to reach the nest before removing the nest and the wasp.
These professionals wear protective gear.
They can also accurately figure out how much to dig into the wall to poke the nest.
Also, professionals have a unique way to dispose of the nest. They also have a vacuum machine that sucks in the wasps and their larvae from the nests.
While an expert pest controller treats your home and property for wasps, you may have to leave your home.
Because during the riddance process, the wasps are very aggressive. They’ll sting anyone who they come across. And trust us, you don’t want to be that someone.
To summarize, here’s how to find wasp nest in your wall –
- You can see holes in the walls. From these holes, you might see wasps coming in or getting out.
- You’ll hear crackling noise coming out of the walls. These sounds are of the wasps chewing through the drywall to make space for the nest.
- Wasp swarms are also an indication of wasp nests in or around your property. Following the wasps’ flight path can lead you to the wasp nests in your walls or elsewhere.
Please do not use any DIY method like a spray or sprinkling powder on the wasps or their nests.
That can be extremely dangerous.
Always take help from an experienced pest controller to get rid of wasps and their nests.
