Generally, pregnant women should try to avoid prolonged exposure to mosquito coil smoke and adopt safe and effective mosquito repellent methods to protect the health of both mother and child.

The smoke released when burning mosquito coils contains various chemical components. Although these components in standard mosquito coils are usually controlled within safe ranges, pregnant women, as a special population, have relatively weaker physiological functions and metabolic capacities, thus requiring cautious attention.

Long-term use of mosquito coils may have certain effects on the respiratory and nervous systems of pregnant women. Additionally, components from the mosquito coils might enter the fetal bloodstream through circulation, posing potential risks to the fetus' growth and development. Although short-term, limited exposure to mosquito coil smoke generally has minimal impact, for safety reasons, pregnant women should still avoid prolonged exposure to mosquito coil smoke as much as possible.

To ensure safe mosquito prevention during pregnancy, it is recommended to use physical methods such as mosquito nets, window screens, and electric mosquito bats. Additionally, some natural mosquito-repelling methods can also be tried, such as placing several open boxes of cooling oil or essential balm in the bedroom, or using low-toxicity products like mosquito repellent wristbands and mosquito repellent patches. Keeping the indoor environment clean and reducing conditions favorable to mosquito breeding are also effective measures to prevent mosquito bites.
