Does mould keep coming back in your home?
Cleaning products do not stop the mould from coming back because airborne spores just regrow. First Light attacks the spores to stop mould re-growing and has been lab tested with a 99.2% reduction in black mould on direct contact.
Independent Laboratory Testing and Literature
Aspergillus niger builds its cell wall around ergosterol.
First Light works because Eugenol (clove) and citral (Litsea Cubeba) disrupt that wall. No wall, no germination.
Industry citations include: Industrial Crops and Products, 2024. Chamber test: Antibiotics, UNSW Sydney, 2022. Essential-oil vapour cut 72% of viable Aspergillus spores in 10 minutes.

Why wiping fails
You never see the moment it starts.
01Spore in the air
Invisible. Thousands per cubic metre. You breathe them in.
02Lands on damp
Grout. Paint. Back of the wardrobe. Two weeks growing before you can see it.
03The patch you see
You reach for the spray. Wipe. Looks clean. Weeks later it is back in the same spot.
Bleach kills what it touches. Porous surfaces are a different story.
Bleach kills mould it can reach. On a hard non-porous surface (tile, glass, sealed bench) it works.
On grout, painted walls, plaster, timber, the story changes. The chlorine sits on top. The water carrier soaks in. The colony under the surface is still alive and the water residue feeds the next round of spores.
How First Light differs
Sprays hit the surface. First Light hits the spore.

Tea tree
Terpinen-4-ol. Damages the cell membrane.

Cedarwood
Fixative. Slows evaporation so the blend lingers.
The third Sunday of scrubbing bleach.
We went away for a fortnight. A cyclone came through Queensland while we were gone and the house was sealed up tight the whole time. We came back to mould on the walls, in the cupboards, in the back of the wardrobes.
We scrubbed with bleach. Two weeks later the patches were back. So we scrubbed again. Then again.
By the third Sunday in a row of scrubbing the same walls, I stopped asking how to get the mould off and started asking what these chemicals were doing to the air my family and our dog were breathing. That question took twelve months to answer.

Questions worth asking
Before you decide.
How fast does it work?
Fresher smell in a week. The mould pattern in your home takes two to four weeks of daily diffusion to break. Most customers see the difference in the third or fourth week. That is why the refund window is 60 days.
How do I use it?
A few drops in the Aurala Waterless Diffuser is the simplest way. Any diffuser you already own works too.
The Aurala Waterless Diffuser is best because it nebulises cold. The six oils leave the bottle unchanged and reach the whole room. Warm-water diffusers dilute the oils and lose some to steam.
Safe around kids and pets?
Yes. Six food-grade essential oils. No bleach. No solvents. Diffuse in ventilated rooms. Do not let anyone inhale the stream directly. Birds and reptiles are sensitive to essential oils, keep the diffuser out of those rooms.
What if it does not work?
60-day money-back guarantee. Reply to any email from us with one photo. Refund the full price same day. You keep the bottle. No phone call, no return shipping, no haggling.
How long does one 15 ml bottle last?
Roughly four weeks of daily use in one room. About the cost of a coffee a week if you diffuse every day.
Fine in a rental?
Yes. No dripping, no residue on tiles or paint. Ventilation only. No landlord conversation required.

from 18 reviewsGreat products, arrived quickly, great customer service. Too early to tell effectiveness but smell is beautiful & diffuser so easy to use.
Beautiful and thoughtful packaging, fast deliver and a lovely product. Easy easy easy
Worth every cent, works like magic and smells incredible.
So easy to use
Love it! Smells so good and it’s like magic, I don’t get how it works so well but it does. It has really cleared up my bathroom mould drastically.
Simple and easy to use!
My house smells amazing !
Easy to shop with and product came quickly.
I love the smell. I love the packaging. I love that it’s stopping mould from growing in my bathroom sink and no mould has come back on the ceiling so far. I love the diffuser as well! Great battery life, lovely and compact and looks lovely and minimal and sheek (is that how you spell that word?) Will definitely get me more when I run out.
Very prompt service and FAQs are very useful.
Love the scented aroma as it wafts through rooms and the product is living up to expectations with mould management. The diffuser is a great addition to the product bundle, and I will continue to use and recommend First Light!
I love the smell of this essential oil combination, its perfect in a defuser and very pleasant.
Works well, smells great and shipping was fast.
Shopping experience was great and speedy delivery!
Beautiful product! Everything about the brand from the luxe packaging to the functionality of the oils is very considered down to the smallest details. I now have 2 of the waterless diffusers and they are so much easier to have going than the water ones (constantly having to top up with water and also it adds more moisture to the air which isn't ideal). The oil blend smells amazing and makes the air feel fresh. I'm looking forward to seeing the difference it makes to the recurring mold growth in our house.
