This screen can be used as either as a propolis grid for harvesting propolis or as a travel screen.
For harvesting propolis place the screen on the topmost frames in the hive, ensuring the maker's name is facing downwards. Leave until the bees have deposited propolis in the gaps in the screen and then remove. Place the screen in a large plastic bag in the freezer for at least 24 hours. Remove from the freezer and while still in the bag bend the screen to dislodge the propolis.
For use as a travel screen simply reverse the roof on one of our bee box hives and place the screen underneath the reversed roof. This only works on our hives as the roof has been designed to leave a clear air gap underneath it when it is turned upside down. Secure the hive with a strap, ideally two, ensure the varroa tray is removed and there is room for air to circulate around the hive and take your bees to the blossom! When you arrive just turn the roof back up the correct way, leaving the screen in place for the moment. This will ensure the bees are disturbed as little as possible. remove the screen at the next inspection - unless you want to collect propolis of course!
For long journeys or in high temperatures, ensure the bees remain cool by spraying with water through the screen. If you are concerned the bees may overheat fit an empty super under the screen. This will give the bees plenty of clustering space and ensure air can circulate amongst them easily.
