WANGSHI 10pcs Beekeeping ABS Plastic Needle Style Square Queen Bee Cage Catcher Separator Rearing Tools (10)

These are very sturdy; these permit worker bees to pass - so these cages cannot be used for introduction - build your own cage if you want to do queen introduction.But, if you want to confine a queen for a day or two to get some known-age larvae for grafting - these little cages are ideal.You could also contain your queen honeybee to confine her to a most-nearly non-laying lifestyle for a while to modulate how many bees you have or to break the brood-cycle (and the mite-cycle) in preparation for mite treatment (or as a mite treatment); since your treatment may not treat capped-brood, simply move this to a not-yet-treated colony (hive); Your queen might escape in the long run as the workers may burrow thru non-plastic foundation to get to her and release her.

Cheap & cheerful plastic queen cages. Obviously I don't know yet how long the plastic will last with the 90+F temps inside a hive, but first impressions are good. If you're against plastic being around your bees then look elsewhere, otherwise this should do the trick.
