The German cockroach, Blattella germanica (L.) (Blattodea: Blattellidae), is a serious pest in residential housing with control administered mainly through application of pesticides. Integrated pest management (IPM) involves a combination of strategies aimed at reducing pest populations. Over a 27 mo study period, we determined levels of German cockroach populations in rural manufactured residential homes: before IPM implementation (Pre-IPM), the period when residents were educated on IPM strategies (IPM-education), and during education and insecticide application (IPM-education plus bait). Sanitation level in the IPM-education phase (2.8) was significantly different from that in the Pre-IPM phase (3.9) and was accompanied by a decrease in trap catch. Sticky and jar traps were deployed in kitchen areas to assess levels of infestation. Trap catch from all participants during the 3 phases was significantly different. Mean cockroach catch per participant per trap was 20.5 ± 4.1 during Pre-IPM, 13.2 ± 2.2 during IPM-education, and 3.9 ± 0.7 during IPM-education plus bait treatment. During the last 3 mo of the study, the population level declined by 86% when compared with that during the Pre-IPM phase. Victor Roach®pheromone sticky traps captured more cockroaches (19.2 ± 1.9) than jar traps (7.2 ± 1.1), accounting for 73% of cockroaches captured. Traps caught more nymphs than adult cockroaches. Trap catch was unevenly distributed, with the highest (34%) catch occurring around refrigerators. We conclude that the inclusion of education of residents in German cockroach IPM programs will make implementation and sustainability of cockroach control more efficient.
