Can electric mosquito coils kill mosquitoes or drive them away

Electric mosquito repellent mainly uses its repellent effect to keep mosquitoes away, and generally does not directly kill mosquitoes. The working principle of electric mosquito coils includes heating and evaporating mosquito repellent ingredients, interfering with mosquito perception, and reducing the probability of biting. The active ingredients in electric mosquito coils, such as pyrethroid compounds, are released into the air after heating, which can interfere with mosquitoes' sense of smell and nervous system, making it difficult for them to locate the carbon dioxide and sweat odors emitted by the human body, thereby reducing mosquito approach and biting behavior. This type of ingredient mainly plays a repellent role at conventional concentrations and has a weak lethal effect on mosquitoes. Experiments have shown that the number of live mosquitoes in the space where electric mosquito coils are used will significantly decrease, but most of them will be driven away rather than dead. When using a special formula of electric mosquito repellent liquid at high concentrations for a long time in a closed space, some mosquitoes with weaker resistance may experience nerve paralysis and death. This situation can only occur if it lasts for several hours and the space is poorly ventilated, which is less common in daily home environments. Some industrial mosquito repellent formulations that have added highly effective ingredients such as chlorpyrifos do have fumigation effects, but for household products, the concentration of ingredients is usually controlled within the range of repellent to ensure safety.

When using electric mosquito coils, attention should be paid to indoor ventilation and avoid prolonged use in a sealed environment. It is recommended to use physical mosquito prevention measures such as mosquito nets and window screens. Pregnant women and infants should check the product instructions before using the room. Regularly replace the electric mosquito repellent liquid to maintain its mosquito repellent effect. If a large number of dead mosquitoes are found, check whether the concentration is abnormally high due to product leakage.
