Dump the baking soda into a small bowl. Add the essential oil drops and stir together, breaking up any clumps.

Strip the linens off the bed and wash them in hot water with a few drops of eucalyptus essential oil.

Sprinkle the entire baking soda mixture on the bare mattress.

Let it sit for at least an hour and up to 48 hours - the longer the better.

Vacuum up the mixture and replace the linens when dry.
