Wasps like paper wasps, yellow jackets, and bald-faced hornets build their nests in higher echelons of your home.
But wall cavities can also be entrance points for wasps to build their nests in the walls.
This guide will reveal how to know for sure that there’s a wasp nest in your home’s wall.
You’ll find out the signs that tell you for sure that there’s wasp nest behind the wall.
Let’s get into it.
Signs Of Wasp Nest In The Wall
Wasp Swarms Around The Wall
If there’s a wasp nest in the wall, then there will be quite a few wasps flying around the wall.
That’s a clear sign that wasps are carrying the food and nesting materials to feed their larvae and to expand the nest.
Wasps have nothing to do with a cement or wooden wall unless there’s a nest inside them.
Normally, wasps will hover around flowers and over trash in the garbage bins to feed.
So, if you’ve noticed too many wasps flying around the wall, look for the second sign.
Stream Of Wasps Entering And Exiting Wall Cavities
Wasps entering and exiting the wall cavity or a crack is a sure sign that there’s a nest in the wall.
And the more wasps are entering and exiting the hole, the bigger is the wasp nest behind the wall.
Wasps are indiscriminate when it comes to choosing which wall they need to pick to nest.
They can nest in the drywall, and in the walls of your bathroom, garage, and basement.
Crackling Sound Coming From The Wall
Wasps will chew on the bricks and the wood of the wall to expand their nest.
That chewing causes a faint crackling sound which is audible, especially during the day.
If you’ve noticed these three signs on the wall, then it’s a sure thing that there’s a wasp nest behind the wall.
Do not try to poke the wall void through which wasps are entering.
Wasps become super aggressive if they can sense the danger to their nest.
They’ll sting the living day lights out of you.
Wasp stings are extremely painful. Wasp’s venom can trigger severe allergic reactions, including dizziness and nausea in people who react badly to bug bites and stings.
Call a pest controller or wasp nest removal service to get rid of the wasp and hornet nests.
Do not try to get rid the nests of stinging bugs like wasps, hornets, and honey bees on your own.
Nesting Sites Of Wasps On Your Property
It’s not just the walls that wasps target to build their nests.
There are other places that you need to be aware where wasps start to build their nests during the spring.
Attics
Your home’s attic receives less footfall, making it a perfect place for wasps to build their nests during the spring.
They’ll sneak through the holes and gaps on your home’s exterior to reach the attic.
Attic is also a place where wasps will spend their winters to hibernate.
Many dead insects exist in the attic, making them an easy food source for the wasps to feed their larvae.
Roofs And Eaves
All types of wasps including yellow jackets and bald-faced hornets also prefer to make their nests on the higher areas of your home.
So, roof spaces including eaves, and soffits are ideal places for wasps to build their nests.
Garden Sheds
Small storage areas in your backyard, like your garden sheds, are cluttered and don’t receive much of footfalls normally.
So, wasps will choose these areas, especially the roof of the garden shed, to build their nests.
Bird Boxes
Tiny boxes on your property, like bird boxes and mail boxes, offer wasps tight sheltered spots that protect their nests from any predator or rain.
So, they’ll choose these places to build their nests.
Wasp nests in bird boxes are harmful for birds. The wasps will sting the birds.
And, not to mention, wasps will sting you if you put your hand inside the mailing box with a wasp nest in it.
Trees
In the nature, wasps build nests up high in the trees.
Wasps sting people who walk underneath the tress with wasp nests on them.
Abandoned grills, tall light fixtures, chimneys, and areas underneath patio, decks, and wood logs are also nesting sites for wasps.
If you’ve noticed a wasp nest in the wall, then inspect the above areas for possible more nests on your property.
Wasps, yellow jackets, and hornets are social wasps that work together to build their nests.
Mud daubers, a type of solitary wasp, will build their nests by mixing their saliva and with mud.
Their nests look like a mound of mud on window sills, or walls, with a hole which is nest entrance.
Wasps, despite being stinging insects, are not pests. They’re beneficial insects and pollinators that play a significant role in the ecology.
