Wire Metal Queen Introduction Cage National 1 Frame

Excellent queen protection to ensure you can requeen the most stubborn colonies. Only difficulty is they were very tight to install into an Abelo brood box (had to press metal ends in slightly to fit.) better fit into the maisemore nuc box but still tight.

Really good product but had to slightly trim to fit comfortably into poly hive

Queen introduced without escorts along with frame of brood and has not been killed so hope for successful introduction

A detailed video would be superb
Great supplier

As previous reviewer notes, in an Abelo hive it it a tight fit, a little "gentle" persuasion does remedy though. Most importantly it works, and works very well. Great for colonies that have been queen less for an extended time, super safe and (as yet) never had an unsuccessful introduction. I think it's the only method where a banked/ posted queen comes back into lay before release into the wider colony, which I suspect is a massive benefit. It does require you to remove 2 frames for space. Is it more far than the masking tape method, yes, but quality queens are expensive. Only 4 stars as would like it 5mm wider/ 5mm shorter and would be great to have catches to hold the roof on when "dropping" in to the hive.

When checking this cage out using an empty Abelo hive I discovered it was a fraction too long so it didn't fit inside the hive.
The Abelo hive has a ridged hard plastic edging to it so there is no give.
I was able to squeeze it into a poly nucleus, so will keep it as my new Queen is due in two days time.
The cage is quite solid so I don't think I can alter it in anyway.
Hopefully others will have a more positive experience with this.
