Find Wasp Nests In The Walls

Where Can You Find Wasp Nests In The Walls? Don’t Ignore These 3 Signs

Wasps build nests inside your home’s wall voids. But where do you look for wasp nests in the walls? There are two kinds of wasps that build their nests inside walls. The culprits are yellowjackets and bald-faced hornets. You can learn in my post about Why Are There Lethargic Wasps in the House?

In late spring, both types of wasps begin to build nests. Nest construction continues throughout the summer. By the end of the summer, your walls could be home to between one and two thousand wasps.

This post will tell you. But, before we begin, keep in mind that “do not try any DIY methods to get rid of wasps and their nests.” The wasps are quite aggressive. In addition, their stings are extremely painful. 

Wasp venom can cause severe allergic reactions in children and the elderly. Wasp stings are also potentially fatal. Contact a pest controller as soon as you suspect wasps are present in your home. Your family and you are safe here.

Let’s get started without further ado.

How To Find Wasp Nests In The Walls?

If you’re not paying attention, the presence of wasps and their nests inside your walls can be tricky. If you aren’t paying attention, it may be difficult to tell if wasps and their nests in the walls are present. Many homeowners ignore some obvious warning signs.

Here are some signs that walls are infested with wasps –

Holes In The Walls

Wasps’ entry and exit points are in unexpected places, such as too high or too low on the wall. Wasps do not make these holes. They already exist. To begin with, the holes could be quite small. Wasps, on the other hand, can dig a little to widen the holes so they can enter and exit.

A few wasps will also be entering and exiting these holes. Wasps can be found on the walls, so keep an eye out for them. Wasps can also eat through walls to build nests, which brings us to our next sign of wasps in walls.

 A crackling noise came from the wall

If there’s one sure-fire way to tell if you have wasps on your walls, it’s the crackling sound. Wasps eating through the bricks of the wall to build nests cause the crackling sound. Wasp nests inside walls can be quite large and bulky.

If left unchecked, wasp nests can grow to weigh eight pounds or more. Wasps must have enough space to build such a large nest. They chew on the wall incessantly in order to create that space.

Wasps have a habit of quickly chewing through the drywall. Chewing produces a crackling sound. Wasps, on the other hand, are not nocturnal like many other bugs. Instead, they are active during the day.

As a result, you are more likely to hear crackling noises from your walls during the day. During the day, keep an ear out for any noise coming from the wall.

Wasp Swarms

It’s not like we’re talking about dry wood termite swarms. In contrast, if you see a swarm of wasps buzzing around your house, it is likely that there are nests nearby.

Wasps that hover around shaded areas, gaps, or cracks in the wall should be avoided. You’ll find them as you get closer to their nests. Beware, however. If you get to that spot, don’t poke it or let curiosity get the best of you.

Wasps are territorial around their nests. They can sting you if you stay near the nest for long. There is more than one string. There may be thousands of wasps waiting to attack behind the wall.

What Are Wasps Nest Facts & Types [ Wasps Nest Removal]

Where do wasps build nests?

Wasps build nests both inside and outside of buildings. These nests can also be found in other places. Wasps prefer to build nests in your home’s shaded areas that are a little higher off the ground.

As a result, wasp nests are commonly found on porch roofs, roof eaves and rakes, sheds, garages, and even the ground. During the autumn season, wasps abandon their nests. They then congregate on tall structures to breed. They do not return to their former home. Wasps are constantly constructing new nests.

What you can do to prevent wasps from building nests in your house and property?

Taking steps to keep wasps from building nests in your home and property can save you from inconvenience and stings.

Here’s what you can do right now to prevent wasps from infesting your home –

  • Caulk or fill all cracks and gaps on your walls, especially on the exterior walls. Rather than using a sealant, use cement to seal cracks. 
  • To prevent wasps from entering your home, install window screens or fly screens on your windows. 
  • Keep your trash bins, both inside and outside your home, free of garbage. As debris piles up, bugs are attracted to it, which in turn attracts wasps. Wasps eat maggots and other insects in the garbage. 
  • Check for gaps or places where the wooden beams are coming through wooden walls. This is an entry point for wasps.
  • You should keep bugs and pests out of your yard if it is lush and green. They attract wasps. 

What NOT To Do To Get Rid Of Wasp Nests?

Many people believe that getting rid of wasps and their nests is as simple as getting rid of moths. After a few hundred painful stings, they realize their error. Wasps, such as horntail wasps, do not all sting humans.

It would be best if you avoided doing so. If you come across any sprays or powders on YouTube or elsewhere, do not use them for the sake of your family’s safety. Away from the walls, yellow jacket nests are being built. The spray will not affect them.

Wasps and their nests must be removed from your walls and property by a professional. To reach the nest and remove the wasp, pest control professionals must cut a portion of the wall.

Protective equipment is worn by professionals in this field. The nest can also be accurately poked into the wall by knowing how much to dig.

Professionals also have a distinct method of removing nests. They also have a vacuum machine that suckers wasps and their larvae from nests. You may need to leave your home while a professional pest controller treats your home and property for wasps.

This is due to the fact that wasps are extremely aggressive during the riddance process. They will sting anyone they come across. You don’t want to be that person, believe us.
