Having seen the odd moth around for a few months we suspected a problem, which I discovered a couple of weeks ago in a basket I have for my hats, gloves and scarf's. It seems that over summer moths have been happily breeding in my winter woolies and the larvae wrecking havoc. My husband and I went through the basket, discarding lots of ruined items. I then washed everything else (even risked it with the woollens) before freezing for 72hrs and dousing the basket in bleach.
I then bought these traps along with the rentokill strips and some cedar balls. We hadn't seen any moths for a couple of days but within minutes of opening the pack two appeared fluttering around them - I was impressed! I put them out around the house and within 12hrs the traps had caught 4 moths between them. They then didn't catch any more until a week later, when 2 more were caught. I am also trying to find an effective method of killing the larvae and eggs (as a combination of washing then freezing, adding cedar balls and the strips have reduced but not eliminated the problem), but these seem really good at catching the adult males which should prevent breeding and hopefully help break the cycle.
