Can diffusing essential oils kill mould?

Mold (or, as the Aussies call it, "mould") is a fungus that grows on organic material in damp areas.

As you know, mould is a fungus. It grows on organic material in damp areas. If you're old enough to remember the damp smell of your old school backpack, that's what we're talking about here.

Mould can cause health issues like allergies and asthma; it is also linked with respiratory problems including chronic bronchitis and pneumonia and allergic rhinitis (also known as hay fever). Mold allergy can be quite severe; symptoms include sneezing, runny nose, congestion or post-nasal drip leading to coughing fits when asleep at night."

Essential oils are basically super-concentrated plant essences, the "oil" part comes from their consistency.

The term essential oil actually refers to the aromatic compounds that give plants their pungent, aromatic flavours. These aromatic compounds occur naturally in leaves and flowers, as well as the roots of certain plants. They're extracted from these sources using a variety of methods: distillation, expression (pressing out), solvent extraction (using chemicals), or effleurage (immersing material in fat).

Essential oils contain many different substances—some are volatile and evaporate quickly at room temperature; others stay put for longer periods of time. You'll find them in everything from perfumes to cooking spices to cleaning products.

The idea of using essential oils to counter the effects of mould isn't new, it's been tried and tested for decades.

Essential oils have been used by humans throughout history not just to clean, purify and fragrance our surroundings but also as an alternative medicine. The use of essential oils in home remedies has been around since at least the 18th century, when they were first studied by French chemist René-Maurice Gattefossé after he burned his hand with a hot water bottle containing lavender oil. He noticed that the burn healed much faster than normal and began examining other properties of these fragrant plants.

The idea that essential oils can kill mould is nothing new--this was discovered by accident during experiments in which rats were exposed to high concentrations of thyme oil for several days (100 milligrams per cubic meter).

The most commonly recommended essential oils for killing household mould are eucalyptus, lemongrass, tea tree and thyme.

These four essential oils are commonly recommended for killing household mould. Consult your local qualified aromatherapist for advise before using any of these suggested methods. Eucalyptus is one of the strongest, so it could be used sparingly and in small amounts (1/4 teaspoon per 8 oz. of water). Lemongrass can be used in much higher amounts without causing irritation to the respiratory system, but you'll still need to dilute it with water if using it around children or pets. Tea tree oil has been shown to kill 90% of mould spores within 48 hours when mixed with water at a 1:32 ratio (1 part tea tree oil: 32 parts water).

Thyme's anti-fungal properties make it a good choice for dealing with black mould growing on walls, floors or ceilings due to its ability to penetrate deep into porous surfaces like concrete and plasterboard as well as porous materials like wood which black mould loves because they hold moisture well due their lack of ventilation between layers.

If you diffused some essential oils in your home and you're still having issues with mould, call a professional.

If you had a professional cleaner come in to clean up the mould, they would be equipped with the right tools and substances to get the job done safely. You also wouldn’t have to deal with the dust that comes from sanding or scraping off of walls and ceilings.

If you've tried diffusing essential oils in your home, but still have issues with mould, we suggest calling a professional cleaner to get rid of it quickly and effectively.
