Good afternoon John this is CJ and I stopped by for a one time bee service. In this case, you have European hornets coming out of the tree at the end of your driveway. I applied to slow acting liquid treatment directly in and around the entrance of the nest. This will leave behind an oil residual that the hornets will drag further and further into the nest until it reaches their eggs and disrupts the reproductive cycle. I then observed hornets coming and going from the nest to ensure that they are coming in contact with the treatment. Give this treatment three days to start showing results. But if you see even a single hornet coming in and out of this tree on the fifth day, call us back to retreat it.
