A robbing screen is a tool used in beekeeping to prevent robbing, which is the act of one hive stealing nectar or honey from another hive. Robbing can occur when one hive is stronger and healthier than another, and the bees from the stronger hive will attempt to steal resources from the weaker hive.
A robbing screen is a physical barrier that is placed over the entrance to the hive. It is typically made of mesh or screen material and has small openings that allow the bees to pass through, but make it difficult for other bees or insects to enter. The screen can help prevent robbing by making it more difficult for the robbing bees to access the hive.
Robbing screens are often used in conjunction with other measures to prevent robbing, such as providing adequate food and water for the hive, reducing the visibility of the hive, and using guard bees or other forms of physical protection.
This is the robbing screen we use on all our hives year round. It’s easy to install and has prevented our colonies from being robbed.
