Management Of German Cockroaches: Time Effort Of Using Baits And Insecticidal Spray

In this study, the use of a gel bait (0.6% Indoxacarb) and an insecticidal spray (2.49% Deltamethrin) applied by a professional pest controller in refugee homes in Berlin was compared, focusing on the time effort of pre-treatment and treatment and the efficacy up to 6 weeks after treatment. No pre-treatment was necessary using gel baits; the time effort was 0.90 min/m² (mean) compared to the insecticidal spray, where the mean pre-treatment and treatment time effort was 2.32 min/m². Both treatments led to sufficient cockroach reduction of 99.7% using the gel bait and 95.7% using the insecticidal spray after 6 weeks. However, gel bait application is simple; no pre-treatment is needed, and residents can re-enter their home directly after treatment
