Mouse Guards on Langstroth Hive


Hi, Newbee here and a quick question about Mouse guards on a langstroth hive. I installed 2 mice guards for the winter. My guards have round holes.
My question is; will the Bee’s still be able to remove their dead Bee’s with the guards in place?

I do have a Flow Hive, do they have or can you purchase a mouse guard?


Yes they can. They can even remove deadies using an upper entrance, so a mouse guard is no problem at all. :wink:

Not to my knowledge. I just made an entrance reducer with a maximum opening of 9mm tall. An adult mouse skull is 9mm across in the smallest dimension (don’t ask how I know, but yes, I did lab work in neuroscience once…), so as long as you keep the opening at that size or less, you will not get an adult mouse in your hive.

You can make such a reducer very simply by gluing (a good PVA glue is fine) craft sticks or paint stirrers into the right size to wedge into the entrance. If the opening is less than 6mm (1/4") tall, because of stick thickness, sand it so that it is bigger than that to help with trash removal and drone escape in the spring. :wink:


Thanks again Dawn!!!

You are a wealth of information and I appreciate you very much!


Could you please put up a picture of the mouse guard fitted


I don’t seem to be able to find a photo of it in place, but here it is before I wedged it into the entrance:

Pretty simple concept. :blush:


Thank you for the photo, why haven’t flow hive included this inexpensive item with the Flow Hive 2?


Remove the mouse guard and turn it upside down and re-fit it to the hive and you will have arches. The bees will freely walk under the arches. With the holes at the bottom they can’t get through the holes. In that position it is a means of locking the bees in while still giving them air flow.

I have added a photo of the mouse guard fitted in this thread, hope you can find it. It not only keeps out mice of course, it keeps out the cane toads which is a much bigger problem in Australia.

If they did you can be sure people would whinge they did it wrong. :stuck_out_tongue_winking_eye:
Do other manufacturers supply entrance reducers/mouse guards with their product?
