Re: Laying Worker in a Top Bar Hive
Do you have more than one hive? If so you can put brood into the LW hive to suppress the laying workers before attempting to requeen.
There's plenty of stuff here about how to requeen a LW hive but just incase you cannot find it, the basics are that the pheremones from normal brood will suppress the laying workers. This is not instant you may need to put young brood in once a week for 3 weeks before the laying workers are suppressed, after which you can safely introduce a caged queen, or alternatively let them make their own queen, which often has around a 75% mating success rate.
If you search the forum you'll get a lot more info about how to requeen a LW hive so no point writing heaps on it here. It will mostly be about langs, but bees are bees you treat you TBH exactly the same.
