American cockroaches? can they climb smooth surfaces
can they climb smooth surfaces
Question is too vague, but surrounded by general yes. I don't know whether their "feet" have sticky pad, but I've never seen a surface that defeated them.
Yes, a bit easily.
Even their poop and such are deposited and virtually stuck to a vertical wall, at times.
Answers: Yes. The sticky substance on the tip of its feet allow it to climb many types of surfaces, rough or smooth.
