Re: Hello from Laredo!!
My son lives in Laredo and works for Homeland Security. I spoke with a large rancher (near Laredo) a few months ago about his feral bees. He has plenty of them. So, bees do well enough there. It rarely freezes, so you should have a long season, that means you will need to solve the mite population issue associated with long brooding seasons -start with treatment free queens and bees, that will help you a lot.
In your location, I'd read up on Joseph Clemens' posts, (on beesource), about recognizing Africanized Honey Bees, in case a swarm takes over one of your hives. I mention this because I've experienced this take over here near DFW. I just killed the queens and brood and provided a queen of known ancestry.
I haven't noticed many honeybees as I walk around my son's neighborhood in Laredo but there is a lot of blooming going on.
Best of luck to you.
I try to learn from my mistakes, and from yours when you give me a heads up :)
