I feel like invasive species would have a harder time living in a new area because they don’t know how to hunt/fight in the new area. I always hear how sensitive animals can be to changes in their environment too, so wouldn’t moving animals to a whole new environment mess them up? Why is this not the case?

Take a predator like the “murder hornet”
You have local species who evolved alongside them. The local honey bees know to swarm the invader and vibrate to increase its temperature and essentially cook it to death.
Now take that same hornet and bring it to America. The American bees never developed this survival tactic. And the hornet can kill the whole hive with impunity.
Not all species can survive other places. But the ones that can, and thrive, do so because the environment is less harsh or dangerous to them than where they were. And thus they breed like crazy and crowd out the original inhabitants.
