Flow hive with vertical pipe for bees entrance

Hi I live in Perth and am wanting a flow hive 2, my issue is

space. I could install a hive under patio area, I would modify the flow hive to have a 90mm pipe that would attach to the exit /entry of the hive for the bees to fly in and out from. It would be vertical straight up through to the top of my patio many be 1.5m to 2 meters. Would this work … please help

Yes those systems do work and there are some great examples around the world. The closest one to you would be the SciTech beehive in Perth where they have a hive inside that has a long entrance to the outside. It may pay to have a visit and see what they have done.

Internal observation hives have these too, most of the ones I’ve seen they are only 40mm or so.

You’ll need to shape the entrance above the patio to ensure water doesn’t get in (your diagram shows a slop back from top to bottom, I’d do that the other way. I’m just not sure what diameter pipe you will want to ensure good bee passage but no comb building. I’m also not sure if it is a long way have an access point at the bottom angle that can be removed so debris can be cleaned.

That should get you started and there will be others on here that will help flesh this idea out.

There are more complicated ways to do it too…


Great thanks for that … now to spend some $$$$

So, i’m wondering if a larger pipe would be better? Thoughts.

I’ve never had a lot of luck with long pipes for entrances. My observation hives always seem to do the best with a short tube. Like not more than 3 feet or less.

Welcome to the forum @9magenta and pmh69.
The ideal entrance according to bee scientist Thomas Seeley is 15 square cm which is about 4.5 cm diameter so 90mm is too large.
I get a lot of information from watching the entrances, having it out of sight wouldn’t work for me. Regular inspections would have the patio buzzing also.
Having the 45° cut on the top pipe would be better inverted to the drawing to keep water out if you were to go this way.

I think you should try a hive on the patio without a pipe first. If you get nice bees, you shouldn’t have much trouble. If you feel you need a pipe after a while, try a shorter one first, then go longer if that doesn’t work.

Getting back to the no-pipe idea. You might get away with a side screen or something like that

So the reason I wanted to have the bees entering above the patio was to not upset my neighbours as we are reasonably close to them. Any other ideas would be great

If neighbours are a potential problem then your pipe entrance could be a goer. You cannot site your hive elsewhere?


I am just being cautious more than anything

You could build a large screen, covered with shade cloth to place between the hive & the neighbors.

I knew I’d seen different chimney hive entrances, just took me a while to find a couple of links. No experience with either design.




Well done Adam, I think the chimney idea looks like a good idea for urban beekeping. I wonder if over enthusiastic guard bees would come down to ground level to attack unsuspecting people.

I guess that is the premise Jeff the guard bees in these ones stay at the entrance of the hive at the base of the hive and it is only the bees leaving the hive that use the chimney.

I have had the odd bee attack me quite a few meters from the hive. It seems a lot of infrastructure for just one hive. But if it works, why not.

All the urban beekeepers need to do then, is stop the bees from swarming. That’s not much of a challenge :slight_smile:

Being in WA I think I will make something but it helps with ideas

It is why I point my backyard hives at walls/fences. The guard bees don’t see us and cause a problem.

I can see why you would make something. Just remember the screened bottom and inspection port opposite the hive entrance in the chimney.
