Continue reading for our complete pet-safe preservation protocol.
According to data from English Heritage, clothes moth numbers in the UK have risen significantly in recent years, threatening historic collections and household wardrobes alike. For the modern homemaker, this presents a frustrating dilemma: you need to eliminate these pests to save your favourite jumpers, but you likely want to avoid endangering your pets or damaging vintage fabrics with harsh toxins. Finding a safe moth repellent for clothes that balances efficacy with safety is often a challenge, as many supermarket solutions rely on aggressive chemicals.
At The Master Herbalist, we approach this problem with a blend of traditional wisdom and modern safety standards. Dispatched directly from Suffolk, our solutions utilise a unique "dry infusion" technology that sets them apart from cheaper, surface-sprayed imports. While many conventional methods flood the air with heavy toxins, our approach focuses on creating a controlled, fragrant barrier. In this guide, we explore why traditional chemical methods may pose risks to your household and how you can implement a natural anti-moth solution that respects both your textiles and your furry companions.

The Dangers of Chemical Mothballs & Sprays
For decades, the standard answer to moth infestations was the chemical mothball, typically made from naphthalene or paradichlorobenzene. While effective at killing moths, these substances release strong, unpleasant vapours that can be harmful if inhaled over long periods. Moreover, the "old smell" associated with them is notoriously difficult to remove from natural fibres.
The Permethrin Risk
Today, many "modern" moth sprays and killers have replaced mothballs with Permethrin, a synthetic pyrethroid. While often marketed as safe for humans when dry, natural moth repellent safety for cats and dogs is a critical consideration. Permethrin is highly toxic to cats because they lack the specific liver enzyme (glucuronidase) needed to break it down.
A retrospective study by Dymond & Swift (2008) published in the Australian Veterinary Journal confirmed that permethrin exposure in cats can lead to severe tremors, seizures, and even fatalities. The Veterinary Poisons Information Service (VPIS) frequently warns owners about the dangers of using dog flea treatments containing permethrin on cats, but the same risk applies to household moth sprays.
Fabric Damage
Beyond the health risks, chemical sprays can be detrimental to the very clothes you are trying to save. Sprays often contain solvents or oil bases that, when applied directly to vintage silks or delicate wools, may leave permanent stains or oily residues. There is a safer, effective way that respects both your pets and your textiles.
The "Master Herbalist" Safety Standard: Infusion vs. Spray
To understand what makes a truly safe moth repellent for clothes, one must look at the manufacturing process. The market is flooded with scented paper for drawers in the UK, but not all are created equal. The primary distinction lies in "Infusion" versus "Surface Spray."
The Difference
Surface Sprayed (Common Import): Many budget liners are simply paper sprayed with fragrance oil on the surface. This leaves an oily residue that sits on top of the paper. If this touches your clothes, it can transfer oil stains. Furthermore, because the scent is only on the surface, it evaporates quickly, offering little long-term protection. Dry Infused (The Master Herbalist): Our process involves impregnating the paper pulp with fragrance before the drying process. This locks the scent inside the fibre structure of the paper. The result is a liner that feels dry to the touch—posing no risk of oil transfer—but releases a slow, steady fragrance release over time.IFRA Compliance & British Standards
Safety is not just about the delivery method; it is about the ingredients. Our fragrances comply with the International Fragrance Association (IFRA) Category 12 standards, which govern safety for air freshening and ambient products. By manufacturing in the UK and dispatching from Suffolk, we maintain strict oversight to ensure our products exclude high-risk sensitizers often found in unregulated imports. This attention to detail ensures that how long scented drawer liners last is measured in months of safe, ambient protection rather than days of overpowering fumes.
The Vintage Preservation Protocol
Preserving vintage textiles requires more than just throwing a sachet in a drawer. Drawing inspiration from heritage conservationists and the aesthetic legacy of William Morris, we recommend a specific "Vintage Preservation Protocol." This two-step barrier system is essential for anyone asking how to store vintage clothes correctly.
Step 1: The Clean & Freeze
Before storing any garment, it must be clean. Moths are attracted to human sweat, hair, and food spills on fabric. If you suspect an item is already infested, "natural" repellents will not be enough to kill the larvae immediately.
The British Pest Control Association (BPCA) recommends freezing infested items to kill larvae and eggs. Place the garment in a sealed bag and freeze it at -18°C for at least two weeks. This non-toxic method ensures the item is pest-free before it enters your storage area.
Step 2: The Ambient Guardian (Drawer Liners)
Once the item is clean, prepare the storage environment. Line the base of your drawer or shelf with Master Herbalist Scented Liners. This creates a "fragrance barrier" that deters adult moths from entering the dark spaces where they prefer to lay eggs. For those who appreciate heritage design, our classic Sandalwood prints add a touch of William Morris textile care aesthetic to the practical function of pest deterrence.
Step 3: The Contact Barrier (Acid-Free Tissue)
The final step answers the common debate of acid free tissue paper vs drawer liners. The answer is: use both.
- Layer 1: Scented Liner (The Repellent).
- Layer 2: Acid-Free Tissue Paper (The Shield).
Wrap your garment in acid-free tissue paper. According to the Victoria and Albert Museum (V&A), acid-free tissue is crucial for supporting delicate fabrics and preventing yellowing. By placing the tissue-wrapped garment on top of the scented liner, you allow the repellent scent to circulate around the item while preventing any direct contact between the liner and the antique silk or wool.
Pet Safety Guide: Lavender, Cedar & Neem
When selecting a safe moth repellent for clothes, "natural" does not automatically mean "edible." Essential oils are potent compounds that must be used with care around pets.
Lavender
Is lavender oil safe for cats in the UK? Generally, yes, when used as an ambient repellent. While concentrated lavender essential oil can be toxic if a cat ingests it or if it is applied directly to their skin, the vapour released from drawer liners or sachets is typically too low to cause harm. However, you must ensure your cat cannot physically reach the sachet to chew on it.Cedarwood
Is cedar wood toxic to dogs? Cedarwood is widely considered safe for dogs and is often used in dog bedding to repel fleas. For cats, cedar is also generally safe in ambient forms like wood blocks or paper. It works by masking the smell of natural fibres (keratin) that moths seek out.Neem Oil
Neem is a powerhouse in natural pest control. Neem oil moth repellent safety is high; it is generally considered non-toxic to mammals and is often used in pet shampoos. Our Lavender & Neem infused liners combine the pleasant scent of lavender with the potent deterrent properties of neem, offering a robust natural defence.
The "No Contact" Rule: Regardless of the ingredient, the safest protocol for pet owners is to ensure no direct contact. If you have a curious dog or cat that opens drawers, consider using hanging sachets high in the wardrobe where they cannot be reached.Frequently Asked Questions
Is lavender oil moth repellent safe for cats?
Yes, when used correctly as an ambient repellent. While concentrated lavender essential oil can be toxic if ingested or applied to a cat's skin, scented drawer liners and sachets release low levels of vapour that are generally considered safe for households with cats. Always ensure your cat cannot chew or lick the product directly.Do scented drawer liners cause allergies?
High-quality, IFRA-compliant liners are designed to minimize allergy risks. The Master Herbalist liners adhere to UK safety standards, excluding high-risk sensitizers often found in cheap sprays. However, if you have a known fragrance sensitivity, we recommend our Unscented Wipe-Clean Liners or handling scented products with care.Can I put acid-free tissue paper over drawer liners?
Yes, this is the recommended 'Vintage Protocol'. Placing acid-free tissue paper over a scented drawer liner creates the perfect storage environment. The liner provides the ambient scent to repel moths, while the tissue acts as a physical barrier, protecting delicate fabrics from direct contact with oils.How long do scented drawer liners last?
Premium infused liners typically retain their scent for 3 to 6 months. This depends on airflow; liners in a tightly closed drawer will last longer than those on an open shelf. To refresh the scent, you can gently rub the paper to release more infused oils or replace them seasonally.Are natural moth killers safe for babies?
Natural repellents like lavender and cedar are safer than chemical mothballs (naphthalene). However, they should always be kept out of reach of babies and children to prevent ingestion. For nursery drawers, we recommend using liners under a layer of paper or using hanging sachets high in the wardrobe.What is the difference between contact paper and drawer liners?
Contact paper is adhesive (sticky) and often made of vinyl/plastic, while traditional drawer liners are non-adhesive paper. Contact paper is hard to remove and can damage wood. The Master Herbalist liners are non-stick, breathable, and infused with scent, making them superior for clothing storage.Limitations, Alternatives & Professional Guidance
While natural repellents are excellent for prevention and maintenance, it is important to understand their limitations. Products like lavender and neem are primarily deterrents—they discourage moths from entering an area and laying eggs. They may not instantly kill a heavy, active infestation in the same way a fumigation treatment would.
For severe infestations where you see visible damage, webbing, or larvae, alternative measures may be necessary before relying on liners. We recommend the "Clean & Freeze" method mentioned above or professional heat treatments, which can eradicate all life stages of the moth without chemicals.
If you discover significant amounts of "frass" (moth waste looking like sand) or widespread damage, we advise consulting a professional pest controller who is a member of the BPCA. Once the infestation is cleared, our infused papers serve as the perfect guardian to prevent their return.
Conclusion
Protecting your wardrobe does not require compromising the health of your home. Traditional chemical sprays and mothballs, while potent, pose unnecessary risks to pets and can damage the very fabrics they are meant to save. By adopting the Master Herbalist method—combining a safe moth repellent for clothes like our infused papers with the physical protection of acid-free tissue—you create a hostile environment for pests but a welcoming one for your family.
We invite you to explore our Suffolk-dispatched collections and discover the difference that British heritage manufacturing makes. Protect your wardrobe with the safety of IFRA-compliant scents and enjoy the peace of mind that comes with a truly natural solution.
