Mosquito Repellent Devices for Poor Areas

Native African residents, especially in poor areas, usually smear red mud or cow dung all over their bodies to prevent mosquito bites. This method has many health problems. By this device, Bidens bipinnata, a native plant that can be seen everywhere in Africa, can be burned, and its odor can achieve a certain degree of mosquito repellent effect. Outdoor workers can insert the device into the soil and use the convex lens condensing principle to make the mosquito repellent grass burn. Artificial ignition can be used to burn mosquito repellent grass on cloudy days or at home.
