There are black outside roaches that big. Some are called Palmetto bugs. And Oriental roaches are black.

And they can be black June bugs.
I have those bugs come around here all the time. They kind of look like mini versions of cockaroaches right? They are either called water bugs or june bugs. I have not a clue of any other name.

There was about 5 of them all around my bin bag, and they were pitch black and could live and were about an inch big. Any ideas what this was?
