A program to reduce pesticide spraying in the indoor environment: Evaluation of the 'Roach coach' project

Purpose: To assess the effectiveness of a pilot integrated pest management (IPM) program in controlling cockroaches in an apartment complex, without pesticide sprays. Methods: A brief educational session and booklet were provided to tenants. Non-spray pest control methods were promoted. A telephone questionnaire was administered at pre- post-test to assess knowledge, attitudes and practices of tenants. Cockroach counts were determined at pre- and post-test. The type and frequency of pesticide treatments were monitored prior to and during the 8-month IPM demonstration period. Results: Overall, the knowledge, attitudes and practices of tenants improved after the IPIM intervention. There was a significant shift in treatment type away from spraying towards paste/gel treatments. Cockroach levels tended to be lower after IPM compared with before. Conclusion: A brief educational session and booklet can influence building residents to accept and comply with an IPM program. This program can be effective in controlling cockroaches without pesticide sprays.
