How Apiguard works

Once in place, vapour from the Apiguard gel is given off. Unlike some other formulations and raw crystals, the release from the gel works steadily and does not disturb the bees unduly. Worker bees climb into the Apiguard tray, remove the gel as a hive-cleaning behaviour and distribute it throughout the colony. The gel sticks to the bees’ body hairs and, as the bees move through the hive, particles are left throughout the hive. The worker eventually throws out the gel it is carrying, but the traces remain until they too are removed later.
