Plain-English summary
A group of dogs wearing a new tick collar (Seresto) was tested to see how well it protected them from the Australian paralysis tick, which can cause serious health issues. Over several months, the collar showed over 95% effectiveness in killing ticks within three days of exposure, although its effectiveness decreased after about 16 weeks. No side effects were reported from the collar. This suggests that the Seresto collar is a reliable option for keeping dogs safe from paralysis ticks, but pet owners may need to replace it regularly for optimal protection.

Abstract
Two placebo-controlled pen studies were conducted to assess the efficacy of an imidacloprid 10 %/flumethrin 4.5 % polymer matrix collar (Seresto®, Bayer; Investigational Veterinary Product (IVP)) against the Australian paralysis tick (Ixodes holocyclus). Dogs assigned to the placebo (n = 8) or IVP (n ≥ 8) groups had collars (placebo or IVP) attached on Day 0 and were infested with 30 unfed, adult, female I. holocyclus at 14–28 day intervals over 227 days. Ticks were counted 24, 48 and 72 h post infestation to determine the acaricidal efficacy of the IVP. The acaricidal efficacy of the IVP 72 h post infestation exceeded 95 % on Days 17 (99.3 %), 59 (99.7 %), 73 (96.6 %), 87 (100.0 %), 101 (96.4 %), 115 (99.1 %) and 171 (95.8 %), but dropped on Days 45 (94.0 %) and 143 (77.8 %), and declined from Day 199 (79.9 %) to 227 (65.5 %). No adverse events related to treatment were observed. This study has demonstrated the excellent acaricidal efficacy (97.9 %) of the IVP collar against I. holocyclus 72 h post infestation over 16 weeks.
