Thieves essential oil

Thieves Essential Oil and diffuserAre you familiar with Thieves essential oil?? In my humble opinion, it is an essential item for every household. I have a diffuser wafting a mist of Thieves into the air of my dining room/living room. Somewhere in my trailer home there is mold and mildew. I can smell it (I’m extremely sensitive to odors). My roof hasn’t leaked but rain water has apparently found its way into other areas?! I keep searching for areas of dampness; I have closet and cupboard doors open for ventilation.
