Plastic in hives


#1

Hi everyone, I am a bee keeper who is thinking of investing in the flow hive because my arthritis makes heavy lifting too painful. I love my bees and in the info on the flows it talks about the plastic gases, is there any reassurance that these gases will not hurt us as well as the bees from a carcinogenic point of view. Also on good old eBay they are selling the complete hives but they are coming from China, does anybody know if these are ok.?
Keep buzzing
Annette

No they are not.
Firstly dubious mechanical manufacture and the low grade plastics used and secondly they are illegal. Many Chinese sellers have been closed only for others to spring up.

If you want piece of mind and something which works, buy the genuine.
Normal langs can be modified to fit Flow Frames. There are instructions on the web site. So you could modify you your hives and only buy the frames.

Edit I had “buyers”

Thank you I will take your advice Best wishes

Wilfred is right, Flow has spent a long time getting this right and ensuring that the plastic is of the highest quality, the chinese knockoffs hurried to get them onto the market and take advantage of the marketing campaign that Flow had developed, so do you think they had time to do their due diligence on the quality of their components, I am not willing to take that risk to save a few bucks.

Thank you, I am grateful for your advice.

The plastic used in Flow frames is BPA-free and food grade quality. It is the same kind of plastic used in baby milk feeding bottles. You don’t need to worry about off-gassing or cancer. :blush:

Hi Annette,

Here is the information about the plastic used in our Flow Frames :

https://www.honeyflow.com/resources/faqs/are-the-flow-frames-made-from-bpa-free-plastic/p/57

We have worked hard to ensure that our Flow Frames are manufactured from the very best food grade materials.

The clear viewing ends of the frames, as well as the honey tube and caps, are made from a virgin food grade copolyester. The manufacturers have assured us that it’s not only BPA-free, but it is not manufactured with bisphenol-S or any other bisphenol compounds.

The manufacturers also advise that third-party labs have tested this material and the results have demonstrated that it is free of estrogenic and androgenic activity. The centre frame parts are made from a virgin food grade polypropylene which is also free from any bisphenol compounds and is widely accepted as one of the safest plastics for food contact.

Plastics have been used for many years in beehives for both brood and honey combs and have not been found to have a negative impact on bee colonies.

The blades in our Flow Frames form partial honeycomb cells. The bees “complete” these cells by joining the gaps and drawing the comb out, then coat the entire cell with wax.

We are constantly striving to further develop and improve our products and continue to investigate alternate materials which may be suitable for manufacturing.

G’day Annette… early anecdotals are not favoring the Shinese Flow product
as being up to wear and tear. Mind you the dinkydi product has to prove it’s
value (long term) in that regard, for all comers.
Sharing your mobility issues I chose to go to the Long hive build, designing
and building my own version of a LongLang - around 60 bars.
For an experienced beekeeper these should be an option considered for
those sunset years, in my view :wink:

Cheers.

There is still heavy lifting involved with owning a flow hive because you need to check on the brood (sometimes quite frequently) to keep the colony healthy.


#10

I agree with @JeffH, but I get around that by putting an empty box next to the hive I am inspecting. I can then take the frames out of the hive, one at a time, put them in order into the empty box beside the hive, and then all I have to lift is an empty box from the original hive on top of the first spare box to start the next layer. Works great if all of your boxes are the same size. :blush: I never lift more than about 10lb during an inspection.


#11

I do the same as Dawn but with regular hives. No heavy lifting.


#13

I don’t do any heavy lifting at all with my Flow frames super or my regular Ideal supers to inspect the brood.

I take the honey frames out one at a time (either the plastic Flow ones on the timber Ideal ones) and do as some others have suggested - I put them in a spare box - or sometimes lean them against something.

If I am honey processing with regular frames, I put them in a wheelbarrow one at a time and take them out one at a time. Honey extracting with the Flow frames I do on the hive.

If I needed to move an entire hive to a different location that is another matter. I wrap an Emlock hive strap around it and get a trolley under the hive. If I were moving the hive a long distance and had to put it on a truck, ute or trailer, I would make an arrangement where I would use a lift etc.

I just can’t see why anyone would have to use heavy lifting in owning or operating a Flow hive - or a standard hive for that matter?


#15

Another option for those concerned about heavy boxes- is a hive consisting of 5 frame Nuc boxes. The weight is quite manageable. Downsides are stability and if you build them up big you’ll need to move more boxes- but the boxes are lighter…

Here’s one I made earlier:

So far this hive is going brilliantly.


#17

I don’t agree with that analogy. My reason being that I’ve seen a multitude of places where bees build their hives/nests. The back of tv sets. The core of a rolled up carpet. The under floor of a trailer boat. A tea chest full of loosely packed antique car parts. Wall cavities, lots of them.

Very seldom do they resemble the inside dimensions of 10 frame bee boxes. Or the inside of a hollow tree for that matter.

I think @Semaphore’s multi story nuc box hive is fine. That’s just my opinion.


#18

“Very seldom do they resemble the inside dimensions of 10 frame bee boxes. Or the inside of a hollow tree for that matter.”

That analogy I make, Jeff, is a loose “mind picture” for human consumption in using our (man’s) adaptation of space, vertically.
Indeed what you have seen is so true of Apis.* as to suggest we can create like environment for them in ‘domestication’’. The extreme - in my view, long held - including the near level tree limb beecoming the Kenyan topbar hive body, or my LongLang under construction as a project.

The formula for required surface area over the Apis.* queen’s laying rate per day aside - the basis for the dimensional argument - there is one signficant mitigating factor allowed for in that analogy of mine, Jeff.
Being, within none of those few spaces you mention , and the many more no doubt others have seen, there are no ‘stairs’!
I am convinced it is the clutter we introduce which changes many aspects of home building for the bees. Or tools of management, if you like… tools bees will work with though not always as we expect, hence my analogy.
Think about that free form comb seen in a wild/feral hive, note the signs of bee workings morphing from brood to storage and back again. in perpituity. Unimpeded by “art deco” they do exist happily in such open spaces.

Oddly enough Trigona (Aussie stingless honeybee) refuse to accept our “mind picture” and so we farm those noncomformists as best as they allow us to. Tho’ introducing a plain horizontal barrier with a gap at the rear can force them to do honey stores in an upper ‘super’, so they are not totally revolutionists :smiley:

luckily no-one told my bees there was any problem and that hive is doing very well :wink: I think stacked Nuc boxes would likely be closer to a natural tree cavity than 10 frame boxes… anyway- we will see with time- I have had that colony in there for around 10 months now and so far so good- it been a very productive hive and I haven’t had any issue yet. The only issue I do foresee as a possibility is increased likelihood of swarming as the entire hive only consists of 10 brood frames and the equivalent of 5 frames in the super (3 flow frames). I could always add another box if I wanted to.

before I made it I did some research and found that there is nothing novel in it- it has been done before and done successfully.


#22

I think all that needs to be said has been.


#24

Hi Jack, if you foresee that hive is likely to swarm, just jump in a bit earlier & do preemptive swarm control on it. Keep one step ahead of them. I’m doing a lot of that myself right now.

The extra colonies & queens you produce will never go astray.


#25

That’s my plan Jeff- as soon as we have a few sunny days I will look into that hive. If it is bursting- or showing swarm signs- I will take a split from it. Also I have a feeling it is currently packed with honey and I will remove and spin any full frames and give the bees some fresh foundation to slow them down and keep them busy. Just half an hour ago the activity at that hive went ballistic as the bees did their daily cleansing flight- the activity just died down:


#26

When you say “showing swarm signs”. I try to do it before they show those signs. That’s what I mean by saying “keep one step ahead of them”.
