I think I posted this on here somewhere before. This is an idea created by an Elementary School's Lego's Robotics Team.
I'll send you the PDF via pm:
Instructions: How to make the Beekeeper 20,000
The Beekeeper 20,000 is a tent system invented by the Blue Rays FIRST Lego robotics team to protect beehives from the aerial spraying of pesticides. On nights that aerial pesticide spraying will occur, place the pop-up, lightweight, easy to use Beekeeper 20,000 over the hive. Use the mister (attached to any garden hose) to call the bees inside and help ensure the temperature stays sufficiently cool. Zip the tent closed until spraying is complete. Once spraying is over, unzip the tent to allow the bees to exit. Remove the tent from the hive as soon as possible once spraying has occurred. Leave the tent outside for an additional few days to allow any further residue from the pesticide to break down and evaporate.
The Beekeeper 20,000 is made from two parts that are readily available on Amazon.com
Gigatent Pop-up Pod Changing Room (Price ranges from $24.50 to $29.00)
MistyMate 15006 Keepin’ Cool Portable Misting kit (Price ranges from $9.90 to $12)
Easy to use and lightweight pop-up tent. Stakes secure it to the ground.
The mister enters from bottom of the tent and is clipped inside the tent, along the sides. It sprays mist at the top center of the tent, over the bee box.
Beekeeper 20,000
The Pop-up tent comes collapsed and in a bag. Remove the tent from the bag and fully open the tent. The tent comes with stakes that can be used to secure it to the ground.
Remove the MisyMate from the box. Only one of the misting nozzles is needed to mist the bees. The other five misting valves should be plugged. You can use the plastic bag that the MistyMate is packaged in to accomplish this. Simply cut five 1”x1” squares from the plastic bag. Before screwing in the gray misting nozzle into the beige misting hose, place one of the square plastic pieces over the hole where the gray nozzle is screwed in. Then screw the gray nozzle and plastic square into the hole.
Be sure to leave the last nozzle at the far end of the MistyMate open (do not plug with plastic).
Next test the mister by hooking it up to a garden hose and turning it on. Water mist should come out of the one open nozzle; mist should not spray from the holes you have plugged.
Attach the MistyMate to the inside of the tent using the clips provided by MistyMate. Clip the one open nozzle to the top center of the tent using the clips.
Be sure to enter the tent, with the hose, from the bottom (underneath) and not through the doorway. The remaining excess hose can then be clipped to the side of the tent all the way to the bottom where it enters the tent.
The hose must enter from the bottom to ensure that no pesticide can enter the tent and mix with the mist.
To protect your bee box from mosquito spraying, lift the tent with the MistyMate attached over the bee box. Unzip the doorway and roll it up. Secure it in the up position with the fasteners on the inside of the Gigatent. You can secure the tent to the ground using the stakes and string provided by Gigatent, by following their directions. Turn on the water mist and the bees should respond appropriately.
At dusk and before Mosquito spraying occurs, unfasten the door flap, roll it down, and zip the bees inside. Keep the mister on until you are ready to remove the tent to prevent bees form overheating. The tent should be removed as soon after mosquito spraying has occurred as possible. If possible leave the empty tent outside for several days to ensure all of the pesticide has broken down and evaporated.
