Septic tank is the main breeding source of mosquitoes in most houses. It is noted that more than 50 % of mosquitoes at home premises are bred in the septic tank. Mini-mosquito furnace is adapted to be installed at the top of the vent pipe of septic tank. The device features a spherical structure made up of stainless steel/aluminium mesh that does not block the air flow, but prevents the mosquitoes from entering/coming out the pipe. The metal mesh globe acts as a furnace at day time.
