This moving screen is actually two pieces of equipment. Beekeepers who move their bees can leave the screen on to open and close the doors whenever they want to go. At the end of the season when robbing is prevalent, you can eliminate robbing by putting the screen on your colonies and opening the top exit above the aluminum curtain. 8 frame only.
Wow this thing is great. I just finished treating my hives with Api life Var and had a major bee kill off in one hive. I have 2 hives and it didnít effect the other hive hardly at all. But I found out that not only will api life var kill the mites it will kill weak, diseased and dyeing bees as well. This is a good thing actually, because you donít want weak and diseased bees going into winter, you only want healthy bees going into winter which clearly shows me I have a problem with that one queen and her genetics. I will be replacing her very soon. Any way because my hive was weakened down so much it started getting robbed out. I know this because my bees are the color of a light leather belt and the bees that were robbing out my hive were yellow. I am feeding my bees now because we are starting to go into a dearth but there are still some things out there for the bees to forage I have the entrance reduced to the large hole and went out to check on them and a robbing frenzy was going on. Bees were fighting on the landing ramp so much that the bees coming in with pollen couldnít even get into the hive. I ran back to the house and grabbed this robbing screen a hammer and some nails and put on my bee suit and ran back out there and put it on the hive. I also moved the lever thingy that blocks off the entrance down to highly restrict how many bees that could go in and out. With in 5 minutes the robbing frenzy was over. All the yellow bees left and my hive went back to normal. These moving and robbing screens should come with all new hives being sold. It should be an integral part of all hives. I highly recommend this product.
