A Singapore company is selling a machine that provides a 24-hr protection against mosquitoes and other biting insects. Called the Mosquito Magnet Liberty Plus, it mimics a human by emitting a plume of carbon dioxide, heat and moisture and Lurex, a short-range attractant. According to the company's website, this precise combination is irresistible to female mosquitoes. As the mosquito approaches the trap hoping to bite a human, it is quietly vacuumed into a net where it dehydrates and dies. This machine doesn't come cheap. It costs close to S$2k!
