🏚️ Wasps in the Walls? How They Sneak Into Andover Homes — and How to Stop Them

You thought the buzzing was coming from outside.
But now it's on the walls.
Near the bathroom.
And louder. 

If this sounds familiar, you’re not alone. During the summer, wasps and yellowjackets don’t just hover around your yard — they often find their way inside your home. 

And in towns like Andover, North Andover, Boston and North of Boston where older homes and wood siding are common, it’s happening more than most homeowners realize. 

🚪 How Do Wasps Get Inside? 

Wasps are excellent at slipping through tiny gaps you’d never think to check. We’ve found active nests in: 

• Attic vents and soffits

• Gaps around window frames

• Behind exterior siding

• Under rooflines and inside wall voids

• Chimney caps and bathroom vents
   

Once inside, they can build large colonies within your walls, chewing through insulation and finding warmth, sometimes just feet from where you sleep. 

🛠️ Signs You May Have a Wasp Nest Indoors 

Not all wasps build visible nests in trees or eaves. Some stay completely hidden until their population grows. 

Here’s what to look for: 

• Buzzing sounds in walls, ceilings, or light fixtures

• Wasps flying in or out of one specific spot on your exterior

• Soft scratching or tapping noises behind drywall

• Warping, staining, or slight bulges in interior walls (caused by large hidden nests)

• Wasps showing up in rooms without open windows

If you’ve spotted any of these signs in your home, it’s time to take action. 

❌ Why DIY Isn’t Safe Here 

When wasps nest inside walls, spraying the outside does nothing. In fact, it might trap them inside — or push them further into your home. 

And knocking on the drywall? That’s just asking for trouble.
