Mosquito repellent is not the same as insecticides (insect killers). Mosquito repellent such as Soffell protects the body against mosquito bites with its aroma which are not favored by mosquitoes without killing them. Soffell can be used directly on human skin to protect against uncomfortable mosquito bites which may cause certain diseases, especially in tropical regions which are still susceptible to Dengue fever and malaria epidemics.
