They have been around much longer than they have been invasive. They only became invasive when human activity transported them from their native environment to a different one without the predators that kept their populations under control. In this new environment their populations explode exponentially and they invade more and more space in that environment, pushing native species towards extinction in some cases.
"Invasive Species" is a term used to describe a species that is taken from it's natural environment and introduced somewhere else. The species then cause harm to the new environment it was introduced in.
exotic species
No, not all introduced species are invasive because they may have a natural predator that will eat them in their new environment. Also because the species can be biologically controlled, chemically controlled or mechanically controlled.
Species that migrate are called migratory species, while species that are accidentally introduced into an ecosystem are called invasive species.
A foreign species introduced from one region to another is called an invasive species. These species can disrupt the natural balance of an ecosystem and have negative impacts on native species and their habitats.

Those are invasive species.

Not all introduced species are invasive; an invasive species is specifically one that causes harm to the environment, economy, or human health in its new habitat. For example, the common house cat, while introduced to many regions, can have detrimental effects on local wildlife, making it invasive in some areas. In contrast, the European honeybee, although introduced to many parts of the world, primarily aids in pollination and has not shown the same harmful impacts, thus not being classified as invasive.
Invasive species
In its natural range in the Americas, raccoons are natives and not an introduced or invasive species. As a result of escapes and deliberate introductions in the mid-20th century, raccoons are now also distributed across mainland Europe, Caucasia, and Japan where they might be considered as invasive.
The Nile Perch is one of the Invasive species located in Lake Victoria, Africa. It was introduced as a sporting fish, but it soon became one of the 100 Worst Invasive Species by the IUCN's (International Union for Conservation of Nature) Invasive Species Specialist Group. Other invasive species include the Nile Tilapia and the Water Hyacinth, which is a water-type weed.
Invasive species. These are introduced species that disrupt the ecosystem they were introduced to, often outcompeting native species and causing harm to the environment.
A species is not inherently native or invasive. All species on Earth have a region to which they are native. If they are introduced to a new area, then they are invasive to that area. The orca has a cosmopolitan distribution, so it is native to oceans pretty much everywhere.
