Article: . Cockroach traps lure cockroaches in and then trap them with an adhesive. Get several of these, and place them wherever cockroaches are known to frequent. While this is an effective way to kill a small population of adult roaches, it won't affect the nest itself. A simple and effective homemade way to lure and trap roaches is with a jar placed next to a wall. This allows the roaches to get in, but not escape. Any bait can be placed in the jar, including coffee grounds and water, but it also works with plain water in drier climates. Again, this is a good way to kill adult roaches, but it doesn't affect the nest and eggs. Take a plastic soda bottle and cut off the top where it curves. Invert the top and place it into the body of the bottle so that it acts like a funnel inside the bottle. Tape it into place around the rim. Pour a bit of water with soap in the bottom of the bottle, and set the trap in a place where roaches hang out. They'll craw into the trap and drown.
