One of the most common mistakes we see homeowners make is sealing the hole where wasps are entering and exiting while the nest is still active.
It seems logical: close the hole and the wasps can’t get back in. Unfortunately, it can create a bigger problem.
When an active entrance is sealed, wasps may simply find another way into the nest. Even worse, wasps trapped inside a wall, soffit or roof cavity may begin searching for another way out—and that route can lead inside your home.
The colony should be properly treated before the entry point is sealed.
Why Are Wasps Coming Inside My House?
Wasps inside your home don’t necessarily mean a nest is sitting somewhere in the living space. The colony may actually be hidden inside a wall, soffit, attic or another part of the structure.
We’ve seen untreated nests become particularly noticeable when temperatures begin to drop. Wasps seeking warmth can move farther into the structure and eventually appear inside the house.
If you’re suddenly finding multiple wasps indoors, particularly when the weather becomes cooler, there may be an established nest somewhere within the structure.

Why Isn’t Wasp Spray Getting Rid of the Nest?
A can of wasp spray can work when you’re dealing with a small, completely exposed nest. The situation is very different when the nest is hidden inside a soffit, wall or roof cavity.
We’ve had customers call us after going through five cans of wasp spray trying to eliminate a nest they couldn’t even see—and the wasps were still active.
The problem is simple: spraying the entrance isn’t necessarily treating the nest.
If wasps are disappearing through a small opening in your soffit or siding, the actual nest could be much farther inside the structure. Killing some of the workers entering and leaving won’t necessarily eliminate the colony.
That’s why identifying the nest location and using the appropriate treatment method is so important.
A Good Rule for DIY Wasp Removal
If you can clearly see a small, exposed nest and safely reach it from the ground, a product specifically labelled for wasps may be an option when used exactly according to its directions.
If you can’t see the nest, wasps are entering your home through a hole, the nest is underground, or you’re dealing with a large bald-faced hornet nest, repeatedly spraying the entrance is unlikely to be the best solution. Customers have spent upwards of hundreds of dollars trying to treat a wasp nest they cannot see without success. If a wasp nest is located between the walls or soffit, your best bet is to call a licensed professional.
And whatever you do, don’t seal an active wasp entrance before the colony has been eliminated.
