Flexible plastic propolis grid, also known as propolis screen, is designed for the collection of propolis. Valid for Langstroth and Dadant hives, measures 425x510mm.
Using a propolis screen, also known as a propolis grid, you can encourage bees to deposit the bee glue in one place. The screens, or grids, are made of plastic dotted all over with punched-out holes one-eight to one-fourth inch wide. The bees will seal up the holes with propolis, and when it is full, you can extract the screen.
Immediately place the screen in the freezer and leave until the propolis segments become frozen. When they are ready, flex the screen just as you might an ice cube tray and the propolis pellets will fall out. You can then put the screen back in the beehive to encourage further cultivation of propolis.
