MedicalResearch.com Interview with: Changlu Wang, PhD The Urban Entomology lab Department of Entomology Rutgers University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cockroaches are an important public health pest. They carry pathogens and produce allergens which causes asthma. Some residential communities always have chronic cockroach infestations. This study is designed to understand the environmental and behavioral factors associated with cockroaches in low-income homes occupied by senior citizens. We found 30% of the 388 surveyed homes had German cockroaches. Sanitation and residents’ tolerance are two factors significantly associated with the presence of cockroaches. A dirty apartment is 2.7 times more likely to have German cockroaches. Gender, ethnicity, and clutter level are not associated with presence of cockroaches. People would be bothered by cockroaches when more than 3 cockroaches are caught in sticky traps when 4 traps were placed per apartment over 2 weeks period. A high percentage (36%) of residents were unaware of cockroaches when they were caught in traps in their homes. These findings are important for property managers and policy makers in designing better intervention methods to reduce the cockroach infestations.  (more…)
