Over the years, kerosene's uses have widened to include cooking fuels, insecticides and even entertainment in performances that incorporate fire breathing and fire juggling.
As a pesticide, kerosene is extremely effective at killing large numbers of insects--- most notably, bed bugs and head lice. It can even be applied to standing pools of water to kill mosquito larvae.
As beneficial as kerosene has been over the centuries, it is, nevertheless a potent toxin, where ingestion of the liquid or even prolonged inhalation of its fumes can be deadly.
Light the lamp as the dark of evening falls,
the bright, crisp, clear flame ascending,
fear not the black of night's feral call,
bask in the lantern's glow, unending.
