Boiga irregularis
To be honest, it’s very difficult to control organisms once they get established. For the future, prevention is the best method of control and why it is so important.  Getting laws changed and new ones passed is extremely difficult because each segment of this trade has a lobby that fights any regulation on their industry. I believe that discovering new pathways and eliminating them may have possibilities of slowing down the flow of new organisms.
