They order them, because people ship them. I know several big name breeders who ship to Florida...not knowing (or caring) it could end their business, or at least land them with large fines. I can understand a private party shipping to florida, not knowing about the law...but a breeder? No excuse, no excuse at all. Its not like the remaining 47 states are not providing enough business...everyone is setting monthly quota's due to demand.
I usually get several orders a month from Floridians, despite the the no florida orders policy being listed on my website (in bold red text no less). Typically I catch it right away, and let them know why I issued a refund. A couple times however, I have made it to the shipping day before I realised their location...once I was at the post office :shock: . I personally would love to ship to Florida, but state law is state law. Shame on those breeders who ignore such laws.
All that said, Florida's climate is very much conducive to the survival of most tropical roach species. Species like Eublaberus Posticus are prolific breeders, and could severely impact the local eco-system. Posticus have been known to eat other inverts, and I can only imagine what they would do in large numbers. Dubia and other species like Discoids would be a little more benign, but in large numbers who know's what they could do.
BTW, I believe you need a permit to raise non-native tropical roaches in Florida. So those buying them may be putting themselves at risk.
I apologize for the rant
