The use of a 4% (w/w) deltamethrin collar (Scalibor ProtectorBand) in the extended control of ticks on dogs.
Deltamethrin (4%, w/w) formulated in a polymer matrix system (Scalibor ProtectorBand, Intervet International BV) was evaluated for the prevention of ticks on dogs. Controlled laboratory trials were conducted, wherein dogs wearing anti-tick collars were compared with control dogs and artificially infested by adult Ixodes ricinus and/or Rhipicephalus sanguineus ticks. The activity of the collars increased from 24 to 48 h post-treatment (pt) wherein tick numbers were reduced to 78.7% for I. ricinus and to 77% for R. sanguineus. The proportion of ticks controlled after the second infestation on D7 pt increased to 99% for I. ricinus and 99.5% for R. sanguineus. For I. ricinus adult ticks, an efficacy of 95.4% was reached over a period of 5.5 months and approximated 90% for R. sanguineus. Hence, the efficacy of the deltamethrin-impregnated dog collar was >90% for 6 months against both tick species. There was no significant difference between the efficacy of the collar against either R. sanguineus or I. ricinus. A subsequent field study wherein 82 dogs were wearing the collar and monitored for tick infestation indicated that the duration of efficacy was between 5 and 6 months.
