Dengue, a mosquito-borne disease, was a growing menace in India with the number of cases rising exponentially. Most Indians were unaware that Dengue mosquitoes bite during daytime. Hence, they stuck to their age-old cultural practices of using mosquito repellents only during evenings & nights. By using children as change agents, Good knight was able to drive awareness and cause a behavioural change in consumers and enable them to proactively protect themselves from Dengue. The success was reflected by a stark increase in household consumption, sales & household-base of Good knight’s products and the tremendous buzz created online.
