Current cockroach management almost solely depends on chemical control, such as toxic baits or chemical sprays. Although some cockroach bait products are highly effective, cockroaches and cockroach allergens continue to be widespread and major health hazard among U.S. public housing complexes. Repeated use of chemicals poses direct hazard to residents and causes cockroach resistance. This study is intended to develop a community-wide integrated pest management (IPM) program and compare its efficacy with traditional baiting method. The IPM strategy included education, exclusion, flushing and vacuuming, baiting, and trapping. The baiting treatment used Maxforce FC Select (0.01% fipronil) gel bait only. Cockroach infestations were monitored at 0.5, 1, 2, 3, 4, 7 months after initial treatment. The costs for IPM and bait only method were compared. Results showed that IPM provided better monitoring and control than bait method. Significantly longer time was needed for the IPM program. However, we expect IPM will be economical for long term management of cockroach infestations. Getting cooperation from tenants was the key to a successful IPM program in multi-family housing units.
