So I am inspecting under the sink right now because the piping is where the roaches will travel along most frequently. Its got the moisture, its got everything on the pipe and a lot of these roaches will come up the pipes, just crawl right up the pipes and crawl into your bathroom spaces from the pipes most pipes are going to have a little bit of a an area around where the pipe comes out of the wall enough space for the roaches to climb into your bathroom.
