Mosquitoes have been a big problem in urban and rural areas. Carriers of deadly diseases like malaria, dengue and chikungunya, mosquitoes pose a serious health threat to humans. Among the several toxic and non toxic methods that have been devised to keep the mosquitoes away, mosquito repellents are one of the most economic and widely used. Using a simple electrical heater, a refill that contains a liquid which disrupts normal activity of mosquitoes, one can get relieved from these small creatures within minutes.
