This study evaluated the effectiveness of a neem extract-based product to control O. sylviarum infestations in commercial laying hens. The birds were divided in 3 groups, which received 2, 3, or 4 applications of the product at 7 day intervals. The results obtained allow the conclusion that the neem extract at 2% is effective to control infestations by O. sylviarum, and at least 3 sprays of the product are required weekly for an effective control of the parasite.
