In beekeeping different types of grates are used, among the most popular: the propoleo grating and the queen excluder. As it is known, the bees protect and seal all the holes, holes, spaces, cracks of the beehive and stick all its elements with propolis and for its collection it is necessary to have some special grids that we have for sale, destined to the accumulation of the product. And when we work with vertically developed beekeeping, it's difficult to control the queen going up to lay eggs on the rise (which is meant to be just a honey store). There is a solution for this: queen exclusion grids. These grids have holes with enough space to prevent the queen, but not the worker bee.
