We started using robbing screens to prevent carnage by wasps. During the summer months, we started to notice wasps trapping bees exiting the hive, trapping them against the landing boards, biting the bees heads off and flying off with their bodies. We increased our wasp traps, which you can see here, Wasp Trap Movie, but we still needed to do more.
Mike made a few screens that needed to be screwed into the hive body. That was a disaster. You must put these traps on at night, so the bees can orienent themselves in the morning and remember how to get back in. Even with pilot holes, I was having a heck of a time trying to screw the robbing screens in, the hives were slipping off the screened bottom boards, bees were getting angry, I needed help just to attach them, it was not working. I ended up tying the screens onto the hive bodies with baling string. Not a pretty site.
Then my very inventive hubby, tired of hearing me complaining, came up with a few straps of metal that he attached to the sides of the robbing screen. They have a little point on each side that grabs the wood and stays in place. Easy to put on and easy to take off.
After several models, we came up with the one in the pictures. They are reversible with a closable entrance. One side has a wider opening. Once on, you can turn it either way.
All Robbing Screens are weatherproofed and ready to go on your hives. Remember to put them on at night.
New Design. You might notice a change in our design. On the robbing or tab side, we made the bottom part into a built in entrance reducer. A customer told us he had such severe robbing that he took off the tab of our old style robbing screen and flipped it upside down so it was a combination entrance reducer. It was such a great idea, we changed our design of the bottom bar on the tab side, widened it and cut a notch. This way, when you turn the robbing screen to the reduced side, you have an entrance reducer making it easier for the bees to defend the narrow space as well as a way to close off the screen.
