The aim of this study was to evaluate the effectiveness of insecticide‐impregnated curtains against the entry of phlebotomine ( D iptera: P sychodidae) flies into experimental slatted hen houses in an area endemic for A merican cutaneous leishmaniasis ( ACL ). Three treatments in experimental dwellings containing three chickens each were applied using, respectively, an impregnated curtain ( IC ), a non‐impregnated curtain ( NIC ) and no curtain ( NC ). A control site without chickens ( WC ) was included. The study used permethrin at 0.05 g/m 2 . During each month for 1 year, each experimental hen house randomly received all treatments. Phlebotomine sandflies were captured using REDILA BL traps placed inside the hen house. Significant differences in abundances of phlebotomine flies/trap/night were observed between treatments (χ 2 = 17853.58, d.f. = 3, P < 0.0001): 59.7% of phlebotomines were captured in the NC treatment, 26.3% in the NIC treatment, 8.0% in the IC treatment and 6.1% in the WC condition. N yssomyia whitmani ( A ntunes & C outinho) was the most abundant species in all collections (89.9%). These results showed a lower abundance of phlebotomines in the experimental hen house in the IC condition than in the hen house in the NC condition ( P < 0.05) and that the presence of NIC represents an effective physical barrier against phlebotomines ( P < 0.05). Therefore, the use of curtains may be an alternative eco‐friendly method for the prevention of indoor ACL transmission in slatted dwellings, which represent a common house type in northeast A rgentina.
