Two metals buried in the ground create a natural insect shield that costs less than five dollars and runs on the earth itself. This is the science of the earth battery — a 270 year old technique that the $5.5 billion repellent industry made sure you never learned. In this video, we trace its history from Abbe Nollet's 1749 experiments to modern peer-reviewed research proving copper's devastating effect on mosquito larvae.
