When do you need them?
I have no sources around here unless you wait a couple months.
If you need them now, even some of the big players down south and out west use about everything they have for packages and generally do not have queen ready now, although that should be changing about any day now.
Of the places I like in the south or out west, I like Hardeman's in Georgia, mainly because I have dealt with them over the years and John and the crew are great "ol boys", if you know what I mean. I also like Honey Land Farms out of Florida, which has great queens. In the west, I have dealt with Olivarz Honey Bees (OHB), and they have never missed a mailing date. Not sure if any of them has queens ready now, but they are good places to start.
Of course I always suggest local stock and sources, but reality is we simply do not have enough breeders and supply in the north.
