Nothing is more frightening than wasps in the bathroom while you’re taking your shower.
These buzzers fly around and can land on your body too. That can lead to a painful sting!
This guide reveals the reasons for wasps in your bathroom. And you’ll also find out how to stop wasps from entering your bathroom.
Why Are There Wasps In The Bathroom?
There are five primary reasons for wasps in your bathroom –
- There might be a wasp nest in your bathroom
- The worker wasps are dying in your bathroom
- The fruity smell of soap and shampoos drew the wasps inside the bathroom
- The wasps are looking for a place to overwinter
- The wasps are out of hibernation
Let’s dig deep into each of them.
#1 – Wasp Nests In The Bathroom
Do you know that wasps can build their nests inside wall cavities? Yes, they can.
And they can also build their nests underneath sinks and behind the medicine cabinet in your bathroom
A small hole or a tiny crack on the bathroom wall is enough for them to sneak inside the gap and build their nest.
And if there’s a wasp nest in the bathroom, then wasps flying inside the bathroom is inevitable.
The worst part?
You’ll see multiple wasps flying inside the bathroom.
If there’s a wasp nest in your bathroom, then there’s a big chance that the wasp will sting you.
It’s because the worker wasps protecting the nest will take you as a potential threat to the nest.
And any threat to the nest can make the worker wasps aggressive.
If you find a wasp nest, don’t try to remove the wasp nest on your own. You’ll meet your worst nightmare.
It’ll be best to call a pest controller to remove the wasp and hornet nests.
#2 – The Worker Wasps Are Dying In Your Bathroom
If you see wasps in the bathroom or your home during the fall and winter months, be sure that these are dying worker wasps.
It’s because the worker wasps finish their lifecycle in the fall.
And they’ll randomly sneak inside your bathroom through the bathroom vents and the gaps of bathroom exhaust fans.
They’ll be crawling haphazardly on the ground like they’re drunk.
Some of these wasps will also appear lethargic or half-dead.
So, sightings of wasps in your home and bathroom in the spring and winter months shouldn’t bother you much.
Take a broom and scoop the dying or dead wasp off the floor. And dispose of it outside your home.
But don’t crush the wasp. Crushing the wasp will cause the pheromones in their bodies to splash out.
It’ll attract more wasps.
#3 – The Fruity Smell Of Soap And Shampoo Attracting The Wasps In Your Bathroom
One of the food sources of wasps is ripe fruit.
So, the fruity smell soaps and shampoos can draw some wasps from the outdoors to your bathroom.
The worst part?
If the fruity scent from your body will also draw wasps to you.
Once inside your home and failing to get out, these wasps can also sneak into your bedroom!
Later in the post, you’ll find out how to stop these wasps, but for now, let’s investigate the final reason for wasps in the bathroom.
#4 – The Queen Wasps Are Looking For A Place To Hibernate
The worker wasps die in the fall and winter months. But the queen wasps don’t.
So, if you notice wasps, which are big, have yellow and black stripes, a noticeable triangular head, and a visible sting at its abdomen, then these are queen wasps.
Queen wasps enter homes in the fall months looking for a place to hibernate.
Their preference to hibernate is places like attic or loft because they’re warm, receive less natural light, and have fewer human footfalls.
While searching these places, wasps can also get in the kitchen, bedroom, and even inside the closet.
There are instances when people found queen wasps hidden behind stored food in kitchen cabinets and food pantries in the winter months.
While hibernating, queen wasps can also appear a bit lazy.
Unlike the dying worker wasps, queen wasps won’t be crawling if you discover them. They’d attempt to escape.
#5 – The Queen Wasps Are Out Of Hibernation
The sudden appearance of wasps inside your home but no visible nests around indicates that the queen wasps are out of hibernation.
And that happens during the start of the spring months.
The queen wasps will come out of hibernation, and they’ll try to move out of your home.
That’s one of the reasons you see wasps in home but no windows are open.
So, they’ll be on the lookout for any vent, open doors, and windows that they can use to fly out during the day.
That’ll make them fly into your bathroom, too, if there’s a bathroom vent or window.
It’s always safe to open the windows and doors and let the wasps fly away on their own.
How To Stop Wasps From Entering In Your Bathroom?
Now that you know the reasons for wasps in the bathroom stopping them is easy.
Here are the steps that’ll ensure no wasps enter your bathroom.
#1 – Cover The Bathroom Vents And Windows With A Mesh
Window screens with fine mesh are a godsend when it comes to stopping bugs and flies from entering your home.
They don’t even block the airflow because they’re perforated. And the window screens are sturdy enough to keep the flying bugs away.
So, install these meshed-window screens in the vents and windows of your bathroom.
You can install them in every vent in your home, especially in your attic vent, which is the entry point for many bugs.
#2 – Remove Any Wasp Nest In Your Property
The source of wasps in the bathroom and your home is a nest in your home and property.
Inspect your home, including your yard and garden, for any wasp nest.
Search the lofty places like the roof eaves shingles on the shed ceilings for a wasp nest.
Do not try to knock down the wasp nest if you find any.
Contact a pest controller to remove the wasp nest.
#3 – Use A Vacuum Cleaner On The Lazy Wasps In The Bathroom
If there are lazy wasps in the bathroom in the late fall and winter or elsewhere in your home, use a vacuum cleaner on them to remove them.
These lethargic wasps in the house are worker wasps. They won’t sting you because they’re about to die.
Even the queen wasps that look to hibernate inside your home during the fall and winter months are less aggressive.
So, you can remove them with a vacuum cleaner too.
Dispose of the vacuum cleaner dust bag with wasps inside it far from your property.
But don’t squash the wasps. If you want to kill them, use a wasp spray on them.
If you see a wasp sitting or buzzing around the bathroom vent, then spraying a wasp spray on the wasp will get rid of it.
#4 – Seal Any Cracks And Gaps On The Bathroom Walls And Floor
Wasps can make nests in the wall cavities of your bathroom.
If you find any holes, cracks, or crevices on the bathroom walls and floor, seal them.
These cracks on the walls and floors can be a breeding and hiding place for many bathroom bugs.
Check the bathroom floor too. The cracks on the bathroom shower grout are also a hiding place for many bugs.
If there are any, seal or repair them too.
#5 – Keep Plants That Repel Wasps
Plants like citronella, mint, sage, chamomile, lavender, and germanium repel wasps.
Wasps and many other bugs hate the smell of these plants.
You can keep these plants in your bathroom and elsewhere in your home if wasps in the spring and summer months are a big issue in your home.
You can also use natural bug repellents like peppermint spray.
The strong smell of peppermint is also a wasp repellant.
You can start using peppermint spray from the late fall months to keep wasps away.
Wasps in the bathroom can be a nuisance and risk. Wasps don’t have a particular liking for the bathroom.
Many people believe that wasps like damp places like the bathroom. That’s false.
The reasons for sighting of wasps in your bathroom vary from season to season.
And this guide revealed all of them depending on the season.
But wasp sightings also mean that there are wasp nests on your property.
So, removing the wasp nest and preventing them from nesting in your property is a long-term solution to keep wasps away.
If you see a wasp nest in your home, do not try to remove it on your own.
The wasps are venomous, and their stings are painful and nasty.
Always hire a pest controller to remove a wasp nest from your property.
