Yeah, the general consensus has correctly identified it.

What's your exterminator going to use? Because there are some on my front porch I'm planning to destroy on Thursday. (I'd like to meet whoever built my current residence. The asshole built a brick/cinderblock house and didn't bother levelling out the crevices where the bricks/blocks were mortared together. Just put in enough mortar to hold them, not enough to make it level. Apparently, roaches think the depressions between the blocks are a good place to lay eggs.)

I was planning to use a hammer and chisel. Crush them and scrape away the remains.
