These sticky traps are effective at catching cockroaches. Just add the included bait or a bait of your choice such as sugar or bread crumbs or rice and place it in an area which is frequented by cockroaches, such as under sink area. The cockroaches will be attracted to the bait and will walk into this trap and get stuck inside on the pad. To dispose, just throw the used trap into the trash bin outside. No mess, No smell, No chemicals.
