Clothes moth killer spray: what to check before you buy

Updated: 23 October 2026

You have a hole in a wool sleeve, or a pale track by the skirting, and amazon.co.uk calls almost everything a moth spray. Some listings are a clothes moth killer spray that claims eggs and larvae. One is a cedarwood mist. Two cans never name an active. This guide is the check before the basket. It uses the six listings in our [moth spray comparison](/hub/pest-control/moth-spray), with GBP prices as captured there. The Products Compared editorial team read those pages and public UK sources on 21 October 2026. We did not run a laboratory test. A qualifying purchase can earn us a commission at no extra cost to you.

What a moth spray has to do

The holes are larval feeding. English Heritage's clothes-moth guidance says larvae hide from a passing aerosol, and that cedar and lavender do not affect larvae already in clothes or carpets. A clothes moth killer spray for existing damage has to say it deals with eggs or larvae. In this set, the three Acana listings and the Zero In ZER434M six-pack state a kill of moths, eggs and larvae. Rentokil PSC100 uses a killer name and the captured page does not add that eggs-and-larvae line. The Clothes Doctor cedarwood and vanilla mist is 250 ml of natural repellent for knitwear, with no named insecticide. If the jumper already has holes, that mist is the wrong job. A pheromone trap is a different tool. That split is on moth spray vs moth trap.

What to read on the listing

Four fields separate these cans. Acana names transfluthrin on the 500 ml fresh-linen spray and on both 275 ml cans. Zero In, £17.21 for six 300 ml aerosols, and Rentokil PSC100, £5.90, do not name an active on the captured pages. That is not proof the can is water. It is proof you cannot check the chemistry until the parcel arrives. The Health and Safety Executive's biocide overview expects you to follow the label and the user category on it. Zero In's title says up to 12 months. Acana's bullets say every three months. Rentokil and Clothes Doctor state none. Only the Acana 500 ml listing states an area, about 13.75 square metres. The two 275 ml Acana ASINs, lavender at £8.68 and fresh linen at £8.95, share one review line of 4.3 from 1,663. Do not add those totals together.

Price bands on amazon.co.uk

Captured shelf prices run from £5.90 to £17.21. Rentokil is the cheapest tin and the thinnest page. It shows 4.4 from 724 reviews. It does not take best value here. That place means the lowest price per millilitre among listings that name an active and score at least 80. PSC100 names no active, so the low till price does not win it. Best value sits on the Acana 500 ml fresh-linen spray at £13.49, 4.4 from 277 reviews, which is also the only coverage figure. Zero In is £17.21 because you are buying six cans, at 4.3 from 5,251 reviews. Who each can suits is on the best clothes moth spray page.

Rules before you click buy

Read the label that arrives. Do not borrow another brand's instructions. A Garden World page for Nippon clothes moth spray says that cypermethrin product should not go on clothing or bedding, and that animals should be out of the room. That is Nippon's label. It is not a sentence on these six pages, so do not paste it onto Acana, Zero In, or Rentokil. Naphthalene mothballs are not the cheaper workaround. Southwark Trading Standards has set out that naphthalene has been prohibited since 2008, and English Heritage says those formulations are banned or not recommended. Pets are a blank on these listings. None of the six pages states a minute count for coming back in. The order of work is on how to use moth spray.

Common questions

Do I need a spray that says it kills larvae?
Yes, if you already have holes in wool or pile. English Heritage says larvae do the damage, hide from a light aerosol, and are not affected by cedar or lavender already in the cloth. In this set the Acana listings and the Zero In title do state eggs and larvae.
Why do some cans not name an active?
On the captured amazon.co.uk pages, Zero In ZER434M and Rentokil PSC100 do not name an active. Acana names transfluthrin. A missing name does not tell you the can is empty or harmless. The check happens on the label.
Is a cedarwood mist enough if I already have holes?
No. Clothes Doctor is a natural repellent for knitwear, at £15.49 for 250 ml, with no named insecticide. English Heritage says cedar does not affect larvae already in the cloth. Use it to freshen undamaged wool.
Are naphthalene mothballs a cheaper option?
They are not a legal cheaper option. Southwark Trading Standards records that naphthalene has been prohibited since 2008, and English Heritage treats those formulations as banned or not recommended. The lowest tin price in this set is Rentokil, with the active still unnamed.
What should the label say about pets and clothing?
Whatever that can allows, in the user category on its own label. These six pages do not answer pet safety in the specification block. Nippon's UK page tells buyers of that spray not to treat clothing or bedding and to remove animals. That sentence is Nippon's.
Does UK's number one on an Acana listing mean a measured rank?
No. It is a slogan on the page, not a result from this comparison and not a laboratory rank. The figures we can cite are the captured price, the star line, and whether the page names transfluthrin, a three-month cycle, and, on the 500 ml can only, about 13.75 square metres.
