The invention relates to a slow-release electrothermal mosquito-repellent incense tablet and a method for making it, which is made of carbon or fiber material and is made of an electric heating tablet containing at least one mosquito killing liquid. At least one upward emitting surface of the electrothermal sheet is prepared by spray or impregnation or film plastic sealing to form a thermostable plastic film layer or a foamed alkali inorganic coating film layer or an organic coating film layer. Thus, at least one surface is made into a heat-resistant film layer containing at least one kind of anti-mosquito liquid, a slow-release electric heating tablet of carbon or fiber material; it can make the active components of the mosquito control liquid contained therein volatilize slowly and evenly during the process of use. It really works from 8 to 10. The effect of repellent and insect control overcomes the disadvantages of the most common use effect of electrothermal mosquito repellent incense tablets, and has the characteristics of simple manufacturing process, convenient use, safety and reliability, and obvious application effect.
