It is said that mosquitoes prefer the blood "sweet." It's actually not a substance but the blood, the sweat, that each of us has different amounts to be closer to or less annoying insects. At least according to research conducted in Great Britain. Some volunteers have made
sting for science in the laboratory. The researchers, having identified those points that were less frequently, they collected their sweat and have distilled, breaking it down into its various chemical elements. Then they inserted the electrodes in miniature on the antennae of female mosquitoes (pictured) - the only ones that bite - and they have tested their appreciation to each chemical. In this way they found the disturbing element that could be used to produce natural repellents that "discourage" especially tropical mosquitoes such as Aedes aegypti responsible for yellow fever in Africa and South America.
But for the moment the pre Pest Control of Mosquitoes, better contact pest control companies, give me the discovery of a natural repelente.
