We always have tea tree oil in the house .. but not because it smells nice, honestly this stuff stinks !! but its great for foot fungus, acne, lice, scabies, fleas, powder mold ( squash plants get it ... especially if i have wheat planted near buy ) , itchy skin. Its also toxic if ingested so don't ! I mix it with water and spray on my plants to help with the powder mold and the one dog always gets a drop or so mixed in with her shampoo during bath time to help with her itchy skin.
