How can I safely remove a wasp that has gotten into my house?

To safely remove a wasp that has entered your house, you can open a window or door to allow it to fly out on its own. If that's not possible, you can use a cup and a piece of paper to trap the wasp and then release it outside. It's important to move slowly and avoid swatting at the wasp to prevent it from feeling threatened and potentially stinging you.
