Well, the problem would be that for a Central American snake species to be found in the Florida Everglades because of a migration event, it would have to come across the Gulf of Mexico in some manner, or else come up through Texas, Louisiana, Mississippi, Alabama, then cross the entire state of Florida without being noticed by anyone. Highly unlikely for that to happen with a large neotropical milksnake, I would think. Those milks can get quite large and it is not like someone wouldn't notice them in their back yard.
Perhaps hitched a ride on a boat across the Gulf? Possible, I guess. But still, in no way could such an event be considered as an "invasion".
