Scientists, with the help of local children in Vietnam have found an alternative way to fight off dengue-carrying mosquitoes. They found out that there are certain types of water bugs that destroy said mosquitoes. They have been placing these bugs in nine areas of north and central Vietnam and they have observed that cases of dengue fever in said areas have been reduced to zero over a five year period. One of the scientists in this research, Professor Brian Kay, from the Queensland Institute of Research, said that this scheme is being extended to 37 other areas of Vietnam but wished to see it used on a global scale.
