ABSTRACT: Seven different treatments consisted of four single applications and three combinations were applied to study the effect of sanitation on the control of the German cockroaches, namely: sanitation, lambda-cyhalothrin 2.5% CS, boric acid dust, imidacloprid 2.15% gel bait, combination of sanitation and lambda-cyhalothrin 2.5% CS, combination of sanitation and boric acid dust, and combination of sanitation and imidacloprid 2.15% gel bait. After 12 weeks, the highest cockroach catch reduction was obtained when using boric acid dust (94.4%), then sanitation and boric acid treatment (93.4%), followed by sanitation and lambda-cyhalothrin (82.5%), sanitation and imidacloprid 2.15% gel bait (77%), imidacloprid gel bait (54.8%), sanitation (17.6%) and finally lambda-cyhalothrin (-31.1%). This result indicates that sanitation has improved the effect of both the liquid spray and the gel and that boric acid seems to have a long residual effect since the top two treatments include boric acid.
