Two studies indicate that mosquito coils - one of the most widely used insect repellents in Asia - can be harmful, especially to children, reports Down to Earth magazine of India.

First, scientists at the University of California, USA, say that the smoldering coils expose users to powerful lung carcinogens. Many families in developing countries use mosquito coils inside their small houses. "Moreover, windows are kept closed during sleeping hours," note the study's authors.

The second study, by scientists from Malaysia and the United States, found that one coil burning for 8 hours "releases as much particulate matter as 75 to 137 cigarettes."

As an alternative, experts recommend plant-based products, such as those made from the neem tree. "They are not only efficient and good for health, but easier on the picket," states the report.
