I have had problems with these moths, but only discovered them after they had decimated my son’s wool carpet and chewed holes in my clothes.
I bought a Pheromone trap from my local shop for £4.49, this included a clear plastic trap and one Pheromone Pad. One month later and the pad is almost covered with male moths. Because this product works so well I decided to find out where these are manufactured. I am now selling them on ebay for £2.99 which included one clear plastic trap and two Pheromone Traps. I can also supply more Pheromone pads for 99p each or 10 for £7.50. My ebay user name is bug-busters look me up I can promise you if you have these moths you will be really pleased with these traps. On my listings I have included a photograph of the trap with the moths so that you can see for yourself how effective they are.
There are other deterrents such as lavender bags hanging in wardrobes to deter the moths, cedar wood is also a deterrent.
