Mann Lake Premium Beekeeping Frames, All-in-One Frame & Foundation, Beeswax Coating, Universal Fit, BPA & BPS Free, 9 1/8 Inches, Natural, 10-Pack

Well made, Quick shipping and Mann Lake is a great company. Only thing that I would like to see is solid plastic so the hive beetles have no place to hide.

Bees were a bit hesitant to take to these, but they eventually did.

There is no question bees like these, I had them sitting in a hive body in the barn for a day and they had to have at least 40 bees checking them out. There is plenty of bee stuff in the barn, super frames with drawn comb, real wax foundation, unused supers boxes. And they do see an occasional bee paying interest. But I have not seen this many bees in the barn even when extracting honey.I will be getting more for a swarm trap.

Standard frames are available with 100 percent US beeswax coatingMade of food grade plasticOne piece design requires no assembly; 4.9 cell sizeComes in black colorMeasures 19-inch length by 1-3/8-inch width by 9-1/8-inch heightI've been happy using these frames. The bees are drawing them out very nicely. Note: if your bees aren't already regressed or already using small cell, it can be a challenge to get them to draw out small cell foundation. roduct was descibed exactlycame properly packedgreat price better than i could buy and assemble myselftrial to see if bees prfeer black over yellow coated frames

Durable and well built

These are awesome

Banding/ packing straps placed around frames inside of shipping box caused warping to several frames and damaged one frame (overtightened). Definitely oncerned about all of the hollow spaces in the frame/ hive beetles

So over the past few years I have converted my hives over to natural cell frames. For those who haven't been following the literature and public discussion among beeks, there are those who believe that one way to help bees defend themselves against mites and encourage overall hive vigor is to let them build their own cells rather than using foundation. Bees in the wild build cells which are smaller than those on commercial foundation. Someone had the bright idea a few decades ago that making foundation with larger cells would yield larger super-bees, so most foundation is around 5.3 - 5.4mm. The problem is, larger cells also allow more room for varroa mites. These Mann Lake plastic frames have cells which are 4.9mm, which is a lot closer to what the bees build in the wild.Thing is though, if I have learned one thing about cell size over the past few years it is this: Bees don't build all their cells at any one particular size. Not 5.4mm, not 5.3mm, not even 4.9mm. Left to their own ways, they will build cells at a variety of different sizes for different purposes. What's more, they will routinely change the size and configuration of cells. A cluster of small worker brood cells on an outer frame in the springtime may morph into larger drone brood cells in the summer, then morph again into honey storage cells in the fall.Thus my recommendation: Buy these Mann Lake frames, then take half of them and cut out the entire center. Use a drill to make a hole in one corner, then insert a jig saw blade and cut out almost all the foundation, leaving just a one-inch or so strip all around the perimeter. After you have done this to half of your frames, then alternate them with the other half (the unmodified ones) in the hive body. The reason for alternating is so that the bees will build their comb straight. If you use all cut frames, the bees will have comb going every which way and you'll have a real mess on your hands. But when you alternate, they will generally build their comb straight.If you're a little nervous about trying this, then do a limited experiment... cut just one frame and insert it in the hive, then observe what happens over the next few weeks. You'll discover that the bees love building comb from scratch much more than they like drawing out foundation. If you're like me, you'll soon finding yourself cutting more and more frames until your hives are pretty much all natural comb.One caveat to this... I would not recommend cutting honey storage frames because natural comb tends to break in an extractor. So if you're like most people and use deep supers for the brood nest and medium supers for honey, then your plan is simple: Cut half of your deep frames and none of your medium frames.I'm no expert, but this strategy has been working well for me. For the past few years my bees have wintered over very well and mites have not been a problem at all. I do not medicate, period. If you want to get into small and/or natural cell beekeeping, these Mann Lake frames are great.
