Hanging in the wardrobes of our flat, alongside our clothes, are a couple of small bags of dried lavender. Like many others, we keep them there to ward off clothes moths, but while offhandedly discussing this a couple of weeks ago I realised that I had absolutely no idea if there was scientific evidence to back up this repellent effect. So, I did what any good scientist would, and started a quest to find out whether lavender’s anti-moth powers were the real deal, or as scientifically holey as the moth-eaten clothes it claims to ward against!
