When an adult cockroach is seen visible outside of hiding spots, what does this usually represent in terms of infestation timeline?

Answer

It is usually the first visible indication that the colony has been active for some time

Because the colony must reach a certain threshold before individuals venture out regularly, seeing one visible adult usually means the underlying colony has already been active for a significant period.
