>>115878Most species of Cockroaches really suck when it comes to fighting, especially the in-house ones. They can survive eternities without food and have good survival instincts, but can't do shit to any predators that can catch them.
House centipedes are really fast, venomous, have insanely good senses of smell and touch on their antennas, and are relatively clever. They know to poison dangerous insects and then run until the poison works, for example.
The only really vulnerable part they have are the legs, and they can shed and regrow them.
