moths are an occupational hazard when you surround yourself with wool sadly I always think of getting moth a bit like kids getting headlice, its no shame to pick them up, but well worth doing everything you can to get rid of them and make sure the pesky blighters don't come back. Regular airing and wearing is the best preservative against them, they prefer to do their evil deeds in quiet corners where we don't notice them, so get those kilts and accessories out and wear them regularly, check them over brush them down and you should stand a good change of if not avoiding damage completely, at least spotting any moths before they get comfy in your best kilt or bonnet.
