My family has been using mosquito-repellent incense to kill mosquitoes, which is cheap and effective, but the smell of smoke is a bit heavy.
The effective components of most mosquito-repellent incense are pyrethroid insecticides, which can effectively kill mosquitoes, with little toxicity and little harm to human body (in line with national standards). Use less mosquito-repellent incense and pesticides, especially pesticides. General pesticides contain trace amounts of pesticides.
