In this study were included 30 goats naturally infested by lice. The goats come from a herd of 300 animals of a local breed, belonging to a private owner from Mogila village, Yambol county. The visit to the farm was a response to a signal of distress from the owner who informed us that the goats were scratching themselves and were expressing strong discomfort. The study proved the presence of sucking lice belonging to the species Linognathus stenopsis, Burmeister (1838) from the family Linognathidae and order Phthiraptera. 28 of the 30 observed animals turned out to be infested (93.3 %). The treatment was carried out with ivermectin (Pandexтм) in dosage 0.2 mg/kg of body weight. The results were observed on the 3rd and the 14th day after treatment. The whole body of all the goats included in the study was inspected. No viable lice were found during the first and the second control examination. The eggs of the parasite which were present on the third day were not discovered on the 14th day which proved the high efficacy of the macrocyclic lactone ivermectin against Linognathus stenopsis after a single treatment.
