The answer to 'wasp in my house' is that a wasp inside your home is likely a nuisance and potential safety concern. Wasps can become aggressive and sting when they feel threatened, which can be dangerous for you and your family. Common causes of wasps getting inside include open windows/doors, cracks and crevices in the home's exterior, or a nearby wasp nest.
If you spot a single wasp, you may be able to safely remove it yourself by trapping it under a glass or container and releasing it outside. However, if there are multiple wasps or you suspect a nest, it's best to call a professional pest control technician. They have the proper equipment and expertise to safely locate and eliminate the wasp nest without risking stings.
