In laboratory and field studies, traps were evaluated to determine effectiveness in the capture of the German cockroach, Blattella germanica (L.). Traps tested included: modified sticky (“Kuru Kuru”; Mr. Sticky), electrified cans, and bottles. Unbaited sticky traps caught significantly more cockroaches than other unbaited designs. There was no significant difference in cockroach catch between bottles or can traps or between petroleum jelly or cans fitted with 18-volt electric barriers. Increased cockroach catch in traps with roughened exterior (paper or sand) was noted. A flat sticky surface was as efficacious as other sticky trap designs tested. In field trials, electrified cans caught significantly more cockroaches than bottle traps. Although large numbers of cockroaches were caught and removed, we conclude that cockroach traps are most effective as monitoring devices, rather than providing acceptable control.
