That's a very bad idea. They're right to be concerned. Over here we do (mostly) reflect on cane toads which are still a problem but perhaps less than feared?, but it was never funny, and nor are fire ants or varroa mite. Fire ants could wreak havoc on enjoyment of the outside, and the wildlife. Varroa is mainly a problem to an introduced species admittedly (native bees are not affected) but replacement pollinators at scale will take time. Dung beetles and catoblastus moth were carefully worked through, took decades of work to decide to release. So back in Cali, bringing the eucalypt in the first place was the root cause.
