This might sound weird, but---has anyone heard of a type of cockroach that look similar to the Am. cockroach except it is very dark in color, does not have the light coloration around the head and squirts what I can only describe as ink when it is sprayed with bug spray? I call it ink because it stains my hardwood floors, so I don't think it is fecal matter or any stomach contents. I live in Georgia and my yard is heavily treed with both pine and oak trees.

Any info or thoughts on this will be greatly appreciated.
