Clear inner observation cover for a Langstroth bee hives. The clear plastic is very tough, and will support feeder jars etc. The wood frame is 3/4″ square, domestic poplar wood. A small piece of fiberglass window screen is included to lay over the opening; this will prevent small hive beetles, wax moths, roaches, etc. from entering through the center breather hole. Small hive beetles do not like the plastic material and do not congregate on the under side of this cover as they do on wooden covers. Beetles retreat down into traps. Bee activity may be viewed through the clear cover in any weather without disturbing them as none of their seals need to be broken and they do not get that blast of fresh air.
