The louse had been responsible for the deaths of many men during the First World War as it caused trench fever and typhus. The remedy had to possess protective as well as killing properties and it was decided it should take the form of powder so it could be dusted into clothing. Over 100 different preparations were tried. The one chosen was the 63rd, hence the name. The active ingredient in AL63 was DDT and was used by many local people as a pesticide on their gardens and allotments.
