We've lived here 7 years and have never seen the rats so bad coming from the alley. They squeeze through a gap behind 1946 3rd St NW's house and come into our yard IN THE DAYTIME. Please do not poison our back yard, our kids play out there daily, but the alley must have a huge rat nest somewhere. It has become a rat factory this spring. It's the alley bordered by 3rd & 4th St NW and U St & Elm St NW. Thank you in advance.
