Is mosquito repellent liquid harmful to pregnant women?

As summer arrives, temperatures rise and mosquito populations increase. Electric mosquito repellent liquids are currently one of the most commonly used methods for mosquito control. But are these liquids harmful to pregnant women?

Are electric mosquito repellent liquids harmful to pregnant women?

Yes, electric mosquito repellent liquids pose risks to pregnant women and should be avoided during pregnancy. Physical mosquito-repellent methods—such as mosquito nets—are recommended instead. Electric mosquito repellent liquids operate by heating and vaporizing active ingredients, which then disperse into the air. These substances—including toxic chemicals and hormone-like compounds—can be inhaled or absorbed by the pregnant woman and subsequently transferred across the placenta to the developing fetus, potentially interfering with normal fetal growth and development. In some cases, exposure may even lead to congenital malformations. Therefore, pregnant women should avoid contact with toxic or hazardous substances and refrain from taking medications not specifically prescribed for pregnancy. Comprehensive prenatal care—including regular antenatal checkups, Down syndrome screening, and fetal color Doppler ultrasound—is essential to ensure healthy fetal development.

Electric mosquito repellent liquids contain insecticides and chemical additives. Moreover, when burned (as in traditional coil-based products), they generate carcinogenic and other harmful substances that can irritate the respiratory mucosa, adversely affecting the pregnant woman’s breathing and potentially compromising her health. While occasional, short-term use is unlikely to cause significant harm, prolonged or repeated exposure to electric mosquito repellent liquids may impair fetal development—particularly affecting the fetal nervous system. This could result in abnormalities in brain development, cognitive deficits, or even miscarriage.

Therefore, in hot, mosquito-prone environments during summer, pregnant women should opt for safer, traditional mosquito-repellent methods—such as mosquito nets or electric mosquito zappers—that effectively deter mosquitoes without posing risks to either mother or fetus.
