How to Protect Wool & Cashmere from Moths Naturally

If tiny holes in your favourite jumpers are driving you mad, clothes moths could be the culprit — and a few drops of essential oil might be the natural solution you’ve been looking for. Our Castle Farm Natural Moth Oilis designed to help protect wool, silk and cashmere from damage, without the harsh smell of traditional mothballs.

Why are moths attracted to wool, silk and cashmere?
Clothes moth larvae feed on keratin, a protein found in natural fibres such as wool, cashmere and silk. It isn’t the adult moths that cause the damage, but the small cream-coloured larvae (about a quarter-inch long). These larvae are often difficult to spot and can go unnoticed until significant damage has already been done — which is why prevention is key.

Dark, warm and undisturbed spaces like wardrobes and drawers create the perfect environment for moth infestation, particularly if garments have been stored unwashed.

Natural help is at hand.
Our Moth Oil, developed specifically for Castle Farm, is a carefully blended natural moth repellent made from 100% pure essential oils, including powerful Cedar, Lavandin and Rosemary. The Lavadin is grown in our fields and distilled on site in our specialist distillery - pure, traceable and strong.

All these oils contain naturally high levels of camphor, which is widely recognised as an effective natural moth deterrent. The result is a fresh, herbal scent that helps repel clothes moths from wardrobes and drawers — without the overpowering chemical smell of old-fashioned mothballs.

How to use Moth Oil?

Castle Farm Moth Oil

Moth Oil has long been a popular choice with our customers to help protect woollens, silks and cashmere. Simply add a few drops to mini Lavender organza bags or cotton pads, then distribute them throughout wardrobes, drawers or storage boxes. Reapply regularly to maintain protection. Our Lavender Bags have handy little ribbon ties so you can hook them over a hanger keeping them close to your woollens. 

What our customers say:

“Haven’t seen any moths in my house since using this product. Would highly recommend!” ⭐️⭐️⭐️⭐️⭐️

“I constantly replenish this oil! I used to get little holes in my woollens and cashmeres but since using this oil 3 or 4 years ago, I’ve basically been able to cut out any moth problems. It’s also a scent that I don’t mind putting into our wardrobe, unlike the old-fashioned moth balls that are way too strongly scented.” ⭐️⭐️⭐️⭐️⭐️

What else can you do to prevent clothes moths naturally?

  • Always wash wool, silk and cashmere before storing. Even small traces of perspiration can attract moth larvae.
  • Use our scented natural Lavender Laundry Fragrance Spray when ironing / refreshing your clothes. 
  • Store clean garments in airtight containers where possible.
  • Vacuum regularly, especially wool carpets and wardrobe floors, to remove eggs or larvae.
  • Keep wardrobes clean, dry and well ventilated.

Combining good storage habits with a natural essential oil moth repellent is one of the simplest ways to protect your favourite pieces and avoid costly damage.
