Plain-English summary
A group of horses in Iceland was found to have an infestation of chewing lice, which can cause skin irritation and discomfort. To treat this, some horses received a single application of imidacloprid, while others were treated twice with phoxim. After 28 days, the horses treated with imidacloprid had complete control of the lice, while only a few lice were found on those treated with phoxim. This suggests that imidacloprid is more effective for treating lice infestations in horses.

Abstract
Infestation with the chewing louse (Werneckiella (Damalinia) equi) can be found on horses world-wide. Louse infestations, including clinical signs of louse-derived dermatitis, are known from Icelandic horses. A clinical field investigation was conducted in Iceland using horses with natural louse infestations to evaluate the efficacy of imidacloprid in a 10% solution in comparison with phoxim in a 0.05% solution. A total of 27 horses received a single imidacloprid treatment using 16 ml of the 10% solution along the mane and on the dorso-lateral trunk. A further 43 horses were treated twice, 14 days apart, with phoxim, using 2 x 50 ml solution applied along the mane and the dorso-lateral trunk. At the final evaluation on day 28, complete control of the lice was obtained for the imidacloprid treated horses and only a single moribund louse was found on two horses treated with phoxim.
