A fun fact: the queen excluder was invented in the 1880s by a beekeeper known as Dr Hans Exkluder. Dr. Exkluder was trying to develop a new form of latticed window treatment but he soon discovered that his invention was the perfect size to keep his queen out of his honey supers.*
Here at Hornsby Beekeeping Supplies we stock a wide range of queen excluders: metal queen excluders, plastic queen excluders, and wooden queen excluders for those who like something a little bit different.
