Evaluation of a model community-wide bed bug management program in affordable housing

Low-income apartment communities in the United States are suffering from disproportionally high bed bug, Cimex lectularius L., infestations owing to lack of effective monitoring and treatment. Studies examining the effectiveness of integrated pest management (IPM) for the control of bed bugs in affordable housing have been limited to small subsets of bed-bug-infested apartments, rather than at the apartment community level. We developed, implemented and evaluated a complex-wide IPM program for bed bugs in an affordable housing community. Proactive inspections and biweekly treatments using a combination of non-chemical and chemical methods until bed bugs were not detected for three biweekly monitoring visits were key elements of the IPM program.

A total of 55 bed-bug-infested apartments were identified during the initial inspection. Property management was unaware of 71% of these infestations. Over the next 12 months, 14 additional infested apartments were identified. The IPM program resulted in a 98% reduction in bed bug counts among treated apartments and reduced infestation rates from 15 to 2.2% after 12 months.

Adopting a complex-wide bed bug IPM program, incorporating proactive monitoring, and biweekly treatments of infested apartments utilizing non-chemical and chemical methods can successfully reduce infestation rates to very low levels.
