1.) The little roaches are the nasty ones.
2.) The big ones are more wood-type roaches.
3.) They do not infest my house, I was taking the trash out, which is kept by the back door, and I had left the door open and I actually seen it run in my house, and it's not actually part of my house, it's more of a garage thing.
4.) I have roach things in there because of my trash being right outside, I figure some may get in anyways because things can always find a way in, so I guarentee you in a day or 2 it will be dead.
5.) It's not a pet either, I will feed it to my emperor if it isn't dead in a day or 2. As I feed my emperor B. Dubia's.
