The dawn of vaporisers heralded a new dimension in the technology of mosquito repellents. They were odourless‚ smokeless and inconspicuously went about their task of getting rid of mosquitos and other such flying pests. Mortein was one such participant in this endeavour to make homes mosquito free. Mortein was first manufactured as an insecticidal powder in 1870 and then moved to producing insect repellents. After changing hands it finally became part of the Reckitt Benckiser family‚ which is one
