Problems solved by technology

Among them, proparthrin has been used for more than ten years, and mosquitoes have produced certain drug resistance to it, so the consumption in the electric heating mosquito-repellent liquid needs to be increased, causing the cost of the electric heating mosquito-repellent liquid to be higher; Although the efficacy of ester is high, its unit price is high, the cost is relatively high, and the cost performance is low. Moreover, the mosquito repellent substances contained in the existing electric heating mosquito-repellent incense liquid are more or less toxic, and long-term use is harmful to human health.
