Abstract
The effectiveness of different methods of external applications of Neguvon and Ivomec for treating infestations with Myobia musculi and Myocoptes spp. in conventional colonies of laboratory mice was investigated.
Ivomec appeared to be effective over a longer period of time than Neguvon. There was no difference in the results obtained with different methods of application, but spraying seems to be more practical for large colonies of mice than individual dipping.
