Problems solved by technology

[0002] Mosquitoes and other insects bring nuisance and harm to human and animal life, and also spread various diseases. At present, the diseases transmitted by mosquitoes and ticks in the world are on the rise year by year. The types of mosquito repellents and mosquito repellants on the market The use of repellents (such as mosquito repellent, DEET, picaridin, etc.) in the environment has also increased year by year, but it has not completely prevented mosquitoes from harming humans, and has also caused the enhancement of mosquito resistance and drug resistance. , only more efficient means of repelling mosquitoes can meet the current requirements
At present, the mosquito repellents used in the market generally have a short repellent time, and increasing the dosage of mosquito repellents will increase the safety risk to the human body.
