Plain-English summary
A group of dogs was tested to see how well two different tick treatments worked: a collar (Seresto) and a chewable tablet (NexGard). The collar showed impressive results, killing or repelling nearly all ticks within 6 to 12 hours, while the chewable tablet was much less effective, especially against certain tick species. The collar consistently resulted in significantly fewer ticks on the dogs compared to the chewable and untreated dogs. This study suggests that the Seresto collar is a highly effective option for protecting dogs from ticks.

Abstract
This randomised controlled laboratory study demonstrated the residual speed of efficacy of an imidacloprid/flumethrin collar (Seresto(®), Bayer) for the control of ticks (Dermacentor variabilis, Amblyomma americanum) at 6 and 12 hours postinfestation on dogs when compared to oral afoxolaner (NexGard(®), Merial). Dogs were randomised by pre-treatment tick counts: Group 1) imidacloprid 10 % (w/w) / flumethrin 4.5 % (w/w) collar, 2) afoxolaner chewable (dosage 3.1 - 6.2 mg/kg), and 3) non-treated controls. Ticks (50/species/dog) were infested on days 3, 14, 21, and 28; live (attached and non-attached) and dead attached ticks were counted 6 and 12 hours later. Efficacy against live D. variabilis at 6 hours for Group 1 was 95 - 100 % and for Group 2 was 38 - 48 %; efficacy at 12 hours for Group 1 was 97 - 100 % and for Group 2 was 27 - 59 %. Efficacy against A. americanum at 6 hours for Group 1 was 94 - 100 % and for Group 2 was < 0 - 38 %; efficacy at 12 hours for Group 1 was 98 - 100 % and for Group 2 was 1 - 40 %. Live and total (total live and dead attached) tick counts in Group 1 against both tick species were significantly lower (p ≤ 0.05) than Group 2 and 3 at all time points. The number of live or total ticks on Group 2 dogs was never significantly lower when compared to the respective number of ticks on Group 3 (controls). This study demonstrated that an imidacloprid/flumethrin collar was highly efficacious (94 - 100 %) at repelling and killing ticks on dogs at 6 and 12 hours post-infestation and was more efficacious than afoxolaner on all challenge days.
