Good afternoon this is CJ and I stopped by for one time the service removing a bald face hornets nest from the wall on the deck. After a couple rounds of poking and spraying, I was able to remove the bulk of the nest and most of the pope. There are still a residual stain and cement left on the wall that power wash will do better to remove then scraping. You may still see forgers returning to this area, looking for the nest for the next few days. The residual of today’s treatment should kill any hornets attempting to reestablish the nest. Today service is good for 30 days
