Abstract: Arthropods such as mosquitoes and bed bugs pose significant public health challenges due to their roles in disease transmission and nuisance. Aedes albopictus is a vector for arboviruses like dengue, chikungunya, and Zika that are sickening to humans, while the hematophagous common bed bug Cimex lectularius, which has resurged globally, causes considerable physical and economic harm. This study evaluated innovative control methods against these vectors, focusing on the efficacy of a transfluthrin-treated polyester fabric (TFT-P) against Ae. albopictus and the effectiveness of insecticidal dusts in lethal harborages to control C. lectularius. TFT-P was evaluated in a semi-field setting using the human landing collection (HLC) technique, comparing two experimental times, morning and evening. The study involved two human volunteers, one wearing TFT-P attached at the back of a black vest and the other wearing the control. Results showed that TFT-P vests significantly reduced mosquito landings and blood feeding, with notable inhibition effects on oviposition and egg hatchability. Protective efficacy was higher during morning than evening trials, correlating with lower temperatures and higher relative humidity. The second part of the study compared six commercial insecticidal dust products against both susceptible and resistant bed bug strains under laboratory and semi-field conditions, evaluated using lethal harborage trap. Silicon dioxide (SiO₂)- based desiccant dusts showed the highest efficacy, achieving complete mortality in both strains at high doses, while pyrethroids were effective only at extended exposure times in resistant strains. These findings suggest that economical products such as TFT-P and SiO₂ dusts can be deployed in controlling Ae. albopictus and C. lectularius, respectively. Further development of these tools, alongside integrated pest management approaches, could enhance public health interventions against both pests
