The mosquito repellent market in India is valued at Rs. 1600 crores and growing at 15% annually. KAPL's brand All Out, launched in 1990, created the new segment of mosquito vaporizers and became the market leader with 60% share within a decade. It faced competition from established brands like Goodknight, Jet and Mortein. Through aggressive and innovative advertising, All Out established itself as the leader in the vaporizer segment. However, issues regarding the toxicity of chemicals used and effectiveness of the repellents have arisen, posing challenges to All Out's leadership position in the future.
