The Acana carpet & fabric moth killer & freshener is a licensed insecticide killing product, not just a repellent, says the company. The product works hand in hand with the new Acana carpet moth trap as an instant action killer for any moths, but specifically for carpet moths. Similar to the carpet moth trap, the Acana carpet & fabric moth killer & freshener also kills carpet beetles, silver fish and dust-mites. Perfectly designed for use on carpets, the product provides protection for larger items that cannot be stored away. Supplied in a 500ml spray, it covers up to 25sq m - the size of the average living room carpet in the UK, says Acana.
