I use to catch brown basilisks in Miami over 25 years ago. They are primarily insectivores. They are part of the landscape
and are one of many new introduced species which are not going to disappear. They have a "Big" python hunting contest
every year and kill a couple hundred pythons from the Everglades. This is the biggest joke in the world. Pythons are here
to stay. I have heard that the pythons were accidently introduced from Hurricane Andrew but I saw pythons before the hurricane.
I use to work with reptiles and I made extra money catching mostly exotic species including Brown anole, Knight anole, Jamaican anole, Nile monitor, crested anole, bark anole, cane toad, basilisk, iguana, spiny iguana, veiled chameleon, Cuban tree frog, curly tail, agama, blind snake, and I am sure I am forgetting more. Iguanas are primarily herbivores but in the wild an iguana will forage. They don't typically strip a tree or plant and kill it. Squirrels do far more damage to fruit and they return every day. If it makes you feel better to kill a reptile, unfortunately irresponsible people have introduced them and there is no way to eradicate them. There is allot of fear associated with reptiles and with it goes tons of misinformation. Now there is a law about keeping large pythons without a permit, TOO LATE!
