Abstract: A roach trap enclosed vessel that has a lower transparent wall to a lower compartment thereof and an upper non-transparent wall to the lower compartment, and has a lower compartment entry port from the upper compartment into the lower compartment and an upper entry port through an upper wall or roof of the enclosed vessel. The roach trap has the lower entry port's lower conical end spaced-above an interior surface or floor of the lower compartment sufficiently to prevent a roach from reaching upwardly to gain escape access thereto, and has a strip of adhesive circumscribing an interior wall within the enclosed vessel barring exit between the lower compartment and the upper entry port. The lower conical entry port is aligned beneath the upper entry port that is also downwardly conically shaped.
