Also, while we are on the subject....Does anyone recommend a site(s), or publications that would help me learn about the native roaches of North America? Bug Guide was suggested to me, and I am sure I will use it. But I was hoping for a more usable field guide kind of thing. I live in New Jersey, so even just roaches of the Northeast, and Southeast Coastal Plain (I take road trips to florida a lot) would be awesome! Thanks so much.
