I am getting ready to requeen a very agressive hive with a new queen.
Also, I want to do all of this at night, since the agressive bees won't sting me so badly in the dark (I hope).
First, nigth or evening is worst choice you can find. Even nice hive will get stungs and bees run everywhere.You trick: If you do that who feed larvae?
If hive is mad, move it 10 feet away and put empty hive in old site. Put frame of brood in new hive.
During 2 days most bees fly into new hive . Youngest will remain in old hive and they are not so bad. Those who move are oldest and have worst temperature.
When in old hive you have less bees it is easier to find the queen.
If you do not find the queen easily and bees are nervous, devide hive with excluder. After 3 days again you may see, where are youngest bees and where queen is laying eggs.
Often bees want to raise it's own queen and they do not accept your queen. But after 6 days emerge queen cells have capped and then they accept what new queen easily.
When you have that new hive and one brood frame, you just take brood frame away after one week and give that new queen. They are not able to raise new queen any more.
The most diffucult part in this case is that bees attach and they became more furious when poison smells. There is no much time to search queen. In the evening some hives have meaning of killing (bears time!).
