With certain antibacterial ingredients, like triclosan, banned in recent years, it's understandable to want a more natural option for banishing bacteria. Whether you're looking to make your own hand sanitizer, toothpaste, deodorant, or cleaning product, the best antibacterial essential oils eliminate germs — all while smelling great and giving you some peace of mind that you're using pure ingredients.

It can seem like almost all essential oils purport to have some sort of antibacterial, antimicrobial, or anti-fungal property, so it helps to know which oils are actually the most effective. One study found that four essential oils in particular — lemongrass, eucalyptus, peppermint and orange — were effective against all of the 22 bacterial strains tested. What's more, multiple studies have found that tea tree oil has both antibacterial and anti-fungal properties. For that reason, those five oils top this list.

That said, another thing to consider is the aromatic profile you're seeking. Eucalyptus and tea tree oil offer sharper, even medicinal scents, so if you're looking for a brighter, zestier fragrance to use alone, or to pair with orange oil, I've also included another great antibacterial option, bergamot.

With that in mind, it's time to shop for the best antibacterial oil for you. All of the options below are bacteria busters that offer versatility of use and come highly rated on Amazon.
