An inexpensive roach trap can easily be made from a deep smooth-walled jar with some roach food inside, placed with the top of the jar touching a wall or with sticks leading up to the top, so that the roaches can reach the opening.
Once inside, they cannot climb back out.
An inch or so of water or stale beer (by itself a roach attractant) will ensure they drown.
The method works well with the American cockroach but less so with the German cockroach.
A bit of Vaseline can be smeared on the inside of the jar to enhance slipperiness.
The method is sometimes called the "Vegas roach trap" after it was popularized by a Las Vegas-based TV station. This version of the trap uses coffee grounds and water.
I suspect that the minimum for this trap is 'Paulaner Weissbier' from München - no doubt German cockroaches are particular with their beer tootangobob said:It is well know that the Germans are fussy with their beer, to catch a German roach you would obviously need a Lager beer, pure with no chemicals.
