In a small bowl, blend the toothpaste and baking soda until you get a smooth paste. Slowly drain in the vinegar: does it foam? That’s normal! Then add the warm water, stirring well. For an even more powerful boost, put a few drops of peppermint crucial oil.

Stream this combination into your small containers, then place them in strategic locations: behind trash cans, near sinks, windows or in dark corners .
