I live in Roanoke Virginia.  I believe that we have outside roaches.  They are extremely large and dark in color.  I believe that they are getting in our house through the basement.  I have started noticing them upstairs in our living quarters, a straggler here and a straggler there.  I have noticed several in the basement, and last year during the warmer months (we have only lived here going on 2 years) I would notice them outside around the neighborhood not only near my house.  My concern is that I can treat the outside and basement of my house, but are they all going to come upstairs???? That’s scary. Shat would be my best method of action against these large unwanted bugs? Any help would be greatly appreciated.
