I had a worker out to my house in the rear alley to treat for rats about a month ago. The worker said that he can treat my yard but the rats will continue to come because the restaurants along U Street that back to the alley behind Wallach place have no rat control bait stations. He said that they were required to do so or could be fined. He was going to talk to the U Street restaurant owners but nothing has happened. None of the restaurants have any kind of rat control. I would like to know the status of contacting them and getting to them do what they have to do.
