Most animals that migrate already reside in areas they find habitable, and have been there for long enough to the local fauna to adapt to their presence.
Things introduced through human actions normally wouldn't be able to migrate to areas that they now inhabit through careless actions such as dumping ballast water, and improper keeping of livestock to name a few, and with no predators to keep the newly introduced to the area species in check they reproduce in mass numbers and out-compete native species for food and resources.
