The invention relates to a device for studying the infestation of honeybee populations with varroa mites. The device consists of a container. The container consists of a material whose rigidity withstands the honeybees’ chewing. The container has an opening of a size through which the honeybees can escape which is provided with a sealing mechanism which permits the honeybees within the container to open the container after a predetermined period of time and escape the container. The varroa mites fall from the bees after exposure to a chemical acaricide inside the container. The technical problem is how to determine the severity of varroa mite infestation in a honeybee hive. This is achieved by holding a number of honeybees in the device for a period of time and counting the fallen mites after the device has removed them from the bees.
