Moth protection buying guide: killer, trap or repellent?

Updated: October 2026

You find two holes in a wool jumper, search for moth protection and meet three products that appear to promise the same result. They do not. A pheromone trap monitors flying males, an insecticidal product works only in the place and manner stated on its label, and cedar or plant sachets repel rather than remove larvae already feeding in cloth. This moth protection buying guide helps you choose the job before the brand. For the products themselves, see our [moth protection comparison](/hub/pest-control/moth-protection). Match the life stage and the location, then check the active, the duration and the warnings instead of relying on words such as lavender or natural.

Kill, monitor or repel

Clothes-moth larvae cause the damage. They feed on keratin in wool, cashmere, fur, feathers and skins. Adults do not eat the jumper, so a sticky board does not mean larvae in a carpet edge have gone. Look for holes, webbing, cases and debris. Carpet beetles can leave holes without moth webbing. A contact spray must reach the target on a carpet edge, curtain or cushion. A hanging unit, sachet or ball is for an enclosed wardrobe, drawer or storage bag, subject to its label. Neither format makes cleaning optional, and neither reaches larvae deep inside untouched cloth or under inaccessible fitted carpet. Cedar and plant sachets may deter adults around cleaned textiles. English Heritage says cedar and lavender do not affect larvae already inside clothes or carpets. Use them where avoiding insecticide matters, not as proof that an infestation has been killed. Our trap or killer guide takes the first two jobs further.

What the label has to show

Start with the named active or an explicit non-insecticidal role. Zero In moth balls and the Acana spray print transfluthrin. The plant sachets say plant based and no insecticide. The pheromone boards call themselves monitors. Several hanging killers and the Acana drawer sachets do not print an active in the amazon.co.uk extract. Check the pack before use. Many products say up to three months. That is a limit, not a promise for every warm or oversized space. Acana’s four-pack of lavender hangers says three months in a bullet and six months in the specification. Reviewers generally describe nearer three months or less. Do not average that disagreement. Replace by the physical label and any date wheel, membrane or end window. Warnings outrank scent. Ready Steady Defend reviewers report a cancer warning and do not inhale on the physical pack, and one quotes transfluthrin at 0.45% w/w. Those are review reports, not copied label text. If the pack differs from the listing, follow the pack.

UK rules before you buy

In Great Britain, use an amateur biocidal product and follow its authorised label. HSE does not endorse a product because a listing contains HSE, so HSE approved is the wrong claim. A permitted active does not prove every product that contains it is authorised for every room or method. Old naphthalene mothballs are not the transfluthrin balls in this comparison. Trading Standards notes that naphthalene has been prohibited for supply in pesticides since 2008. A title that says moth balls tells you the shape, not the active. Keep products away from children, pets, food and any material the label excludes. If somebody feels unwell, stop exposure and seek medical advice.

Which type fits the place

For wool on a rail, clean first, then use a labelled hanging unit in a closed space if you accept insecticide. Set the date wheel when you open it. For folded knitwear, use drawer sachets or balls in the stated quantity. Do not put a rail hanger loose among clothes. Placement is in moth protection for wardrobes and drawers. If you refuse insecticide, wash or freeze suitable textiles first, then use cedar or plant sachets as repellents. Sanding the Besto cedar pieces every two to three months refreshes scent, not a larval kill. The plant sachets have only 44 reviews. The order of work is in how to get rid of clothes moths. Call a pest controller when damage continues in fitted carpet or a sofa you cannot reach. A chimney or loft nest may need a sweep. A textile you cannot safely wash or freeze belongs with a conservator.

Common questions

Does cedar or lavender kill larvae already in cloth?
English Heritage says cedar and lavender do not affect larvae already inside clothes or carpets. They can form part of prevention around cleaned, enclosed storage, but a scent is not a treatment for damaged cashmere. Deal with the textile and the storage area before relying on a repellent.
What does up to three months mean?
It is the longest stated period under the maker’s conditions, not a guaranteed replacement interval in every wardrobe. Space volume, airflow and temperature may matter. Set any date wheel when opening the product, inspect its end indicator, and follow the physical label where the online listing conflicts.
Why is an active missing from some Amazon listings?
An incomplete extract does not identify the contents. It means the listing evidence is insufficient to name the active responsibly. Read the product label on arrival before placing a claimed killer, and return it if the pack, warnings or quantity do not match what you agreed to buy.
Can I buy naphthalene mothballs in the UK?
Naphthalene has been prohibited for supply in pesticides since 2008, according to Trading Standards. Products currently sold as moth balls may use another active, such as transfluthrin, or may be repellents. Never infer the chemical from the familiar product name.
Does an HSE number mean HSE recommends the product?
No. An authorisation number concerns legal supply and use under stated conditions. It is not a consumer endorsement or a comparative performance award. Do not describe a product as HSE approved simply because HSE appears in a specification field.
