DIY entrance reducer - question about design & possible problems

Hi! I’m trying to make a new entrance reducer based on Tom Seeley’s measurements (thanks for the tip JeffH!) and was curious if there is a downside to making it so that it sits against the front of the brood box and not inside the actual entrance. Basically it would be a tall flat piece of wood that would attach to the box the same way that flow hive’s entrance reducer attaches (with those L screw things).

I had made a temporary one to help them defend easily while they were growing in numbers but I think I want to make one with two openings (so they can circulate the air if needed). I have pics showing the temp one attached to the outside of the box (in the way I described above) and was wondering if this would cause problems in the long run. (There’s a gap because I did a crappy rush job making it and it wasn’t screwed in tight, but the new one I make will sit flush.)

Thank you!

Hi Cat, you’re welcome. My thoughts are: anything you do to achieve the desired result will be fine.

Good day.

Is there a link to the thread / comment regarding optimal size for the entrance?

Maybe also why utilize such thick stock? (Was it because scrap that was available or some other reason?).

thanks.

Hi! The piece of wood shown in the pic was all I had at the moment so that’s why it’s so thick. The one I plan to make will be much thinner. The link to the original post about the “Seeley Size” I mentioned is here: Is this an active robbery? - #4 by JeffH

Foxhound Bee Company sells an entrance reducer based on these dimensions but I don’t think it will fit in the flow hive entrance.

Hope this helps!

Thank you very much.

Hi Cat, when I was still using the bottom boards with landing I would reduce the entrances using a stack of 3 paint stir sticks. These are free at paint stores or the paint counter at home improvement stores. They’re easy to shorten to your desired length to create two openings - one at either end of the stack placed in the middle. @JeffH can tell you more about the benefit of this configuration :wink:

Ooh! I actually have a stack of unused paint sticks so I’ll try this first! Perfect! Thanks!!

Thank you Eva, the benefits are self explanatory in the must watch video “City of Bees”. I love that Cat has a stack of unused paint sticks :slight_smile: Problem solved.
