You’ll need to have the shipment held at the hub/office of whatever shipping company is being used. I’m also in central Florida and I have my crickets mailed to me and pick them up at my local usps. You could also pay for overnight shipping if you wanted and make sure someone will be home to bring them in immediately as they arrive.

Even though I have 10 lizards, there’s always plenty of silkies to complete their life cycle of becoming moths, mating and producing eggs. I store the eggs in the fridge and thru the year, hatch out whatever I need. It can be challenging though, and like my recent attempt failed horribly. I was fortunate enough to have 4 survive to cocoon. Silkworms have almost no immune system and can very easily fall victim to bacteria, viruses or mold. This may help if you’re interested in trying.
