This spell is best done during a waning moon, but can be done anytime, as necessary.
You need:
sagebrush smudge stick
bowl of water
matches.
After sunset, light the end of your smudge stick, blowing on the embers to increase the smoke. Go through each room in your house, blowing smoke into the four directions, in each room. While doing this, in each room, repeat:
"I clear this space of all negativity, and of the energy of people and things that have no purpose in this household. I ask that this clearing be gentle and that all of this energy be returned to its source."
When you have done the entire house, return to the room you started with, & lightly douse your smudge stick into the bowl of water, while saying:
"This home is a gentle and supportive environment. I offer gratitude to the universe that this is done. So be it. And so it is."
