We've been using Frontline for years for our termites and removing hornet nests. They seem to like a particular bush. I was able to get an appointment within a few days for Wayne to come out and remove a huge hornet nest that my husband had accidentally found in a bush up front by using the lawn mower. Wayne used a long pole with what looked like a round duster at the end then played tag with the hornet's nest. It was very entertaining to watch him hit the bush and shake around and on(?) the nest then run away. Now the nest is broken into tiny little pieces. Thanks Wayne!
