Fuente: WIPO "varroa" A miticidal beehive entranceway is provided having a solid substrate coated with a thymol-containing composition and having holes dimensioned to compel bees entering/exiting the beehive to walk through the holes and contact the thymol-containing composition, thereby exposing mites attached to the bee to a killing dose of thymol while not injuring the bee. In some embodiments, the entranceway may have agitating bristles (which may be coated with thymol) extending into the entranceway, which contact the body of the bee to agitate or dislodge the mites attached to the bee, further enhancing mite removal or death.
