Laying workers problem?
Laying workers is impossible to recognize because they do not differ in appearance from other bees. No new queen should be placed in such a hive because the bees would kill her. Also, such a colony can't be merged with another colony because the bees from the colony with laying workers would kill the queen from this other colony.
Then what can you do with laying workers?
The first way - easier
1During the day, take a hive with laying workers 20 meters from the apiary. (preferably in front of the apiary)
2Shake all the bees out of it.
3When the hive is empty, remove it from the apiary.
The bees will try to return to their hive, but since they do not find it, they will go to other hives. Colonies will accept ordinary bees but will not accept laying workers.
Advantages - This method is easy and even a beginner can easily apply it.
Disadvantages - You do not save the colony but only the bees that are accepted by other colonies.
The second way - advanced
We will call the hive with laying workers - hive A.
And another, strong hive with a good queen, we'll call - Hive B.
Do this during the day when many bees are outside the hive, collecting nectar and pollen.
1Find the queen in hive B (good queen), put her in the cage and remove it from the hive.
1Open the hive B
2Find the queen.
3Cover the queen with a cage and wait for her to come in. That's ok if one or two bees come in with her.
4Close the cage.
5Close hive B.
2Switch the places of hives A and B.
1Move the entire hive A to the place of hive B.
2Move the entire hive B to the place of hive A.
3Place the cage with the queen in hive A (which is now in the place where hive B was at the beginning).
1Open hive A.
2Stuck the cage with the queen between the frames in the middle of the brood box where most of the brood is.
3Close hive A.
4After 48 hours, release the queen from the cage.
1Open hive A.
2Open the cage.
3Leave the cage in the hive until the queen comes out of it.
4Remove the cage from the hive.
5Close hive A.
You have to put the queen in the cage otherwise the bees from the hive A will kill her because they feel her scent and know that it is not their queen.
The bees that flew out of the hive B, before you switched hives, will return to the place where it was. But since the hives have been replaced, they will enter the hive A thinking that it is their hive. Since these bees bring food, there will be no problems when they try to get into the hive. These bees will find their own queen in a hive (a queen who is placed in a cage and moved from a hive B) that they easily recognize by scent. But since there are laying workers in the hive, these bees will easily find and kill them.
After 48 hours, the scents of bees from hive A, the queen who moved from hive B, and the bees that went out of hive
Since hive B has been left without a queen, the bees will begin to make queen cells in order to produce a new queen. The beekeeper should apply the same procedure as in the first, easier way of replacing the queen. If the beekeeper is in a position, he can instead insert a new queen into hive B.
