is it ok to transfer during the day or should I wait until late evening ?
You can transfer the bees into the new hive at any time - in fact it would be better in the day as a lot of bees would be out flying and not getting in your way. Once you have finished the transfer leave the new hive in the exact location of the old one (first getting rid of the old pile of firewood
) for the bees to settle.
I'm assuming that having a forty mile trip you want to do everything in one day so my advice would be
1. Transfer bees to new hive mid-dayish,after they have been put in their new hive, strap up the whole hive ready to be moved (entrance still open at this point so bees will be flying as normal) at this time of year, as long as you have an open mesh floor, this should be sufficient ventilation for a forty mile journey, leave them settle
2. In the evening, when the bees have stopped flying, close up the entrance and finish securing the hive for transportation and you can then take them away.
3. Orientate the hive in the car with the frames running 'fore and aft' i.e. with the lugs pointing towards the front and the back of the car.
4. as a 'Just in case' drape an old net curtain over the hive in case you have the odd escapee - drive in your bee suit with the veil off so you can quickly make yourself 'bee proof' if the worst happens.
5. When at your destination, put the hive in it's new location and open the entrance, the next day they should re-orientate themselves and when they have settled you can remove all the straps etc.
Of course, this is all dependent on the frames in the old hive being intact enough to facilitate the transfer, otherwise we are talking Bailey change or similar
