The mongooses are very effective in controlling the snake populations, as is the case in Hawaii, but the problem is that they represent an invasive species. As an invasive species, they disrupt the whole ecosystem on the islands, the local fauna can not cope with them because they do not have the defense mechanisms needed, nor can reproduce as fast, and also head to head are out competed, so the local fauna is becoming endangered and in time will probably get exterminated by the invasive mongooses.
