Why don you introduce a predator to simply eat all of the snakes (particularly the mongoose or kingsnake)?
This is probably the most frequently asked question regarding the brown Treesnake. It seems like a simple and obvious solution; however, the many ecological concerns and implications accompanying such a move illustrate the dangers of this tactic. While introducing predators has been attempted in many situations across the world, it has more often than not met with disastrous results. Introducing the mongoose has been attempted for controlling snakes and rats on islands (e.g., in Japan and the Caribbean), but mongoose were found to commonly feed on nontarget species as well as snakes and, while the snake and rat populations continued to proliferate, the more vulnerable nontarget species suffered greatly. As is the case with the mongoose, the kingsnake does eat snakes, but does not include them exclusively in its diet.
