Text: Sustained acaricidal (48 h) efficacy, covering a period of 8 months was 100 % against I. ricinus, starting 2 days after treatment (in vivo), and 100 % against I. scapularis (in vitro), above 97 % against R. sanguineus, generally above 97 % against D. reticulatus and above 90 % for D. variabilis. Repellent (6 h) efficacy 2 days after treatment and continuing for 8 months was consistently 100 % against I. ricinus, and above 90 % against R. sanguineus. Regular shampooing affected efficacy against fleas and ticks to a lesser extent than regular immersion in water. The collars eliminated Trichodectes canis within 2 days and Sarcoptes scabiei within 3 months.
