    I've had a few requests for my robber/moving screen, so here it is.

    First, rip a 1X, two pieces, 3/8 in. thick the length of your entrance. Rip 2 more pieces 6 in. long.

    Cut a piece of 1/8 in. hardware cloth the same dimensions and staple to the two long pieces.

    [​IMG]

    Now staple or nail the two 6 in. pieces to each end, on top the screen' and staple the screen to them.

    [​IMG]

    You now have a robber screen. The bottom board will prevent them from going under, so the only entrance is from the top. The house bees will adjust to it, the robbers will not.

    Next, cut a piece from the edge of a 2X4, which is 1 1/2 in. thick, 1/4 inch and longer than your screen. Notch it on both sides to slide down into the entrance.

    Open entrance.

    Closed entrance for moving.

    That is a nice, neat simple design that
    Uses less wood than mine. How do
    You mount it on the hive?

    It goes across the front entrance, mounted with two small nails or screws.

    And it definiteLy works! I saw a lot of activity in front of the 3 hives I have in my yard and upon closer inspection, realized it wasn't orientation flights but robbing. I had taken the entrance reducers off due to 100 plus degree temps so I first put them back with the smallest opening. I looked up robbing on here and there it was-a robber screen! We're not carpenters but we started building 3. The activity at the hives was escalating even with reduced entries so we put wet sheets on them. Finished screens by dark but decided to install early in the morning. When the sun was fully up the frenzy began again. Couldn't tell 'til the next day if we were successful but when I opened up the East hive all I found were dead bees-even the queen on the bottom board-not a drop of honey left. The middle hive was full of dead bees with a few survivors and all their honey still there. West hive was still bustling with bees, all the honey untouched. We made 3 more screens for our hives 14 miles away in the country and installed them because some of the same activity had started there. It's been over a week and even tho repeated attacks have been launched, none have succeeded so-Thanks, Iddee, my remaining hives are safe and another hard lesson learned.

    I learned to build a more complicated robber screen last year, my hive was small and weak, and the drought/dearth were on. Despite the screen my hive was robbed out and bees killed the first week of October.

    Ironically, I think the bees that robbed them out were a large swarm I lost in May of 2011. And even more Ironically, I think my current "hot hive" were last years robbers. Whoever they are they moved into the beetree in my garden this spring.

    Bees are bees, but robber screens are very good. So are strong hives.

    Blessings on our bees...

    Iddee, do you have pictures of this mounted on hives, both open and closed?

    Can I put a robber screen on at any time or should I wait until all of the foragers have returned? I fear the foragers might have a problem with a new entrance just a few inches away.

    I put my robber screen on at night or around 5 am, predawn when the bearding bees have gone in for the night. (a sprinkler can speed them up, maybe at 11 pm or so.) When all are in, put on the screen.

    I tried to put mine on at nite but the bees were really, really defensive-thought it would be a quick tap of the hammer(didn't put long pants on) and ended up learning a new dance with 5 bees up my britches. Had to wait 'til early the next morning to finish the job.

    find it a little quicker by placing it at night, but they will find it whenever it is placed. A few more minutes won't hurt that much.

    I was going to install screws on the sides of all of my new deeps, to correspond with roughly center for a robber screen. Use plumbing pipe strap, with a snip cut at the right distance for mounting the screen. Have a nuc to move to a deep today. May wait and move it tomorrow, install robber screen screws and mount kit on the empty box first. One thing is for sure. Determined robbers can remove duct tape.

    When I pull the robber screen off of my nuc after the move, I'll take a photo. It mounts into the hive opening itself, no screws or tape needed. Horizontal 1x2 or 1x3 shoves right into the opening, leaving only a half inch entrance INSIDE the screen. Exterior entrance is at the top. Improvement off of last year's design flub.

    I was able to quickly construct a robber screen and get it attached to my hive. In ten to twenty seconds, there was a large group of bees at the entrance unable to get through the screen. A few moments later, a group of bees on each side started to walk up the box and find the entrance at top. They marched right in while a large group continued to mass up at the screened entrance area. It was simply amazing. I sure wish I had a camera around to share with y'all. I'll check things out again tomorrow.

    Thanks for the advice!

    I guess my bees are just dumb. No matter how long the screen is on, they still have trouble getting back in.:sad:

    Try a splotch of paint, any bright color, near the exterior opening. Not too much. Just a little. My deep size robber screen had the same problem when it was all white. So I put a blue splotch by the false opening (also known as beek error with measurement) and a green spot by the real one. No problem since.

    Would it be acceptable to leave the robbing screen on all of the time (except maybe during the winter months)? It seems the bees would orient themselves to use the entrance and robbers would never (or rarely) find their way in.

    Keep on in winter also, good way to keep the mice out of the hive.
