lazy, some of these screens have different configurations for closing or no option to close, just a few holes drilled in the screen. i make my own and use both. a completely closed screen, and a screen with holes drilled in it (i use primarily for robbing situations). when i move a hive i like to use a screen that is a complete closure. i put them on after dusk when the foragers have all come home and the night before i move the hive. sometimes, and for the most part, what you will encounter during warmer weather, you might have bees hanging out on the front porch, so depending on the amount of bees, you might have to smoke them back into the hive, and then quickly place the screen on. you don't need much, and some bees may take to the air.
when i have put the screens on a little late in the dark, i have used a headlamp on low to see what i am doing, or fired up a coleman lantern and set it off in the distance just enough for me to see, or parked the jeep a distance away, and used the headlights, but not facing the hives.
sometimes i move them right then and there, at night, and sometimes i have moved them the next morning. if i move them at night, i keep the screen on until early morning, then remove it, and leave it propped on or near the landing board of the hive, they orient just fine. if i move them the next morning, i let them settle down a little before removing the screen, and then once again remove the screen and leave it propped on or near the landing board. again, the bees orient just fine.
good luck to you lazy!
