Apparently there's a hefty bounty on them.
Troy did another show called “Swamp Mysteries” and in one of the episodes he explained how hurricanes, and the residual flooding, displace predators and thats how we end up with species native to mexico all over the US gulf region. Hurricanes also cause domestic predators to spread throughout the southern states the same way. It’s not always just people dumping exotic pets after they get too big to handle.
Good on them that are doing their best to remove the pythons. I hope they are killing them & not just wasting money moving them where they would be trouble for someone else. Having the bounty on them probably helps considerably.
