Welcome to Beemaster.
Who told you it is too late to start. Don't tell the bees that. Here in Jacksonville it is definitely not to late to get started. Depending on the queen/bees, you might even get some honey. The closer you are to the intercoast the better.
I have removed swarms in October and November and had them make it. Not really the norm but depending on the weather they sometimes make it.
I removed a open air hive that had swarmed in January as I fist size ball and I was called in mid March, 2 years ago, to remove it. It was a great hive. It made a lot of honey for me until it absconded, between flows, this spring.
Time to get going.
