ABC7 Los Angeles County health agency looks into rat-infested Van Nuys home.

VAN NUYS, LOS ANGELES - When night falls, rats come out in full force around one Van Nuys home, and after residents spoke out Monday, city officials are trying to do something about it.

On Monday night, pest control specialist Tito Ortiz was out in the area and observed the rats. He said he saw so many rats around the home that he lost count.
