How To Tell If Wasps Are In Your Walls

How to tell if wasps are in your walls? Wasp infestation is no laughing matter. These pests are intruders in your space!

That’s why it’s essential to get in touch with wasp control before the situation gets out of hand, you know. Wasp nest removal can be challenging; this is especially true for yellow jackets and bald-faced hornets that are known to build their nests inside the walls of people’s homes.

These pesky minor bugs can bring harm to you and those close to you, so it’s best to act fast when a wasp problem arises.

How To Tell If Wasps Are In Your Walls

Wasps tend to find their way into the tiniest of cracks regardless of how big. You might find colonies of wasps right near the cracks or siding on the wall or even towards pipes or knotholes in wooden buildings.

The older your building gets, especially if it’s made of natural materials – such as wood or brick – the more likely it’ll be that a wasp will make its home inside.

1. Wasp Swarms

Wasps are territorial around their nests, which typically aren’t located directly within the home, but you should watch for a sudden increase in wasps flying around your home.

This indicates that there could be a nest by your house or someplace within its vicinity (like under the shed or back porch). Look at where they are flying and carefully study the surrounding area to find where they’re coming from.

If you see some flies buzzing around with a dusty substance on them, this is also another indication that there’s wasp activity nearby because bees tend to clean themselves often.

Seeing these insects will help you find the source of local nests if someone has not yet taken care of them.

2. Holes in the Wall

Holes in the walls, at unlikely places, like too high or too low, are the entries and exit points for the wasps.

While there’s no official confirmation of this theory, it’s believed that these holes are entrances to wasp nests because you may observe a few wasps flying into and out of them.

If these holes aren’t there, to begin with, then one can be assured that the wasps will dig into any existing holes to create their nest.

Wasp nests happen to be similar hideouts as your typical rat nest (which is precisely why some think rats make their nest inside walls).

The appearance of nests within a wall means that countless critters would be entering, leaving through the same hole(s) in question, most likely being wasps leaving after collecting food or returning home with it.

3. Wall is making a Crackling Noise

Wasp nests are more of an issue when they start building their homes in the warmer months.

But unless you have a perfect memory of all the places you’ve seen wasps hanging around, you might not notice until it’s too late.

Early detection is critical, so listen for any buzzing or rattling coming from inside your walls.

If you do catch it early enough, then all that damage is being done in the cavity between your exterior and interior walls, not to your interior wallboard itself (which would be much more expensive to replace than it already will be).

Where do wasps build their nests?

It’s not only inside the walls where wasps build nests. There are other places too. Wasps prefer to build their nests in shaded areas of your home that are slightly high from the ground.

Such as underneath eaves and rooflines, sheds, garages, cornices and rakes. So wasps like to make nests around fences, decks and in between railings they can use to perch on.

So they have height when they land but also when they take off again to fly away with pollen or nectar if your local environment has any flowery surprises in store for them!

But during the fall months, when food becomes scarce due to temperature changes, wasps will abandon these nests before returning in springtime as queens to claim new crevices for their hives.

Wasps always build nests in recent locations. It’s beneficial to find out what structure nearby may harbour potential sites for these insects by watching from afar.

So you know better where best to get rid of any incoming pests should the problem arise.


In this piece, you have learned how to find a wasp nest in your Wall. Please do not use any DIY remedies to clean the area or try to rid yourself of the infestation on your own, and doing so can be extremely dangerous. Always let an experienced pest controller take care of the problem for you.
