Polystyrene Hives

[robin118]

I have got 20 mb poly Langstroths. I have used them for 4 years and would not recommend them. If i could go back I would probably go for swienty Langstroths but have no experience of them.

M.B. Langstroths are neither top or bottom bee space making them incompatible with other wooden and poly langstroths. They have a lip on the top of the boxs that fits into a groove on the bottom of the box above. This makes them secure when strapped for moving but makes it hard to put boxes, roofs, feeders on without squashing bees. The feeders only have the lip on three sides so they let in water if left on over winter and because the lip is only on three sides the feeder can not be upturned to feed fondant. If you use a perspex crown board sold by mb dont put it on top of the feeder because of the three lips there is a gap just big enough for bees to find their way in drowning a lot and also causing robbing. They are made from high density poly though and even though they have short comings my bees do well in them and this has not put me of using poly but if going for a full size hive ( I have not used the m b nucs but have heard good thing about them) I would choose another manufacturer.
I hope this makes sense and helps.
