FINIS New Booster Mosquito Coil

The free end of the FINIS New Booster mosquito coil should be lit and kept in a convenient place in the house. At least one window should be kept open during use so that mosquitoes can escape. When the coil is lit in the house, at first it seems as if mosquitoes have increased in the house, because the vapors of the active ingredients from the burning coil enter the house from all sides and attack the mosquitoes, as a result, the mosquitoes move around like crazy. It seems that mosquitoes have increased after lighting the coil. A 10'X12' ft or 120 sq ft room requires one coil to be lit.
