Plain-English summary
Sixteen beagles were tested to see how well a spot-on treatment called K9 Advantix worked against ticks. The dogs were either treated with the product or left untreated, then exposed to a tick-infested area. The results showed that K9 Advantix was very effective, killing about 88% of ticks within three hours and maintaining over 93% effectiveness for up to 28 days. This means that using K9 Advantix can significantly reduce tick infestations on dogs, helping to keep them safe from tick-borne diseases.

Abstract
This study evaluated the efficacy of an imidacloprid 8.8% w/w + permethrin 44% w/w spot-on topical solution (K9 Advantix, Bayer Animal Health) against Amblyomma americanum using a natural field exposure model. Sixteen beagles were divided into two groups of eight dogs each. One group of dogs was treated with K9 Advantix and the other group served as untreated controls. On day -1 and at 3, 7, 14, 21 and 28 days after treatment, the dogs were walked for 80 minutes in an A. americanum-infested habitat at the Konza Prairie Biological Station in Northeastern Kansas. Postexposure tick counts (efficacy evaluations) were conducted on each dog at 3 and 48 hours after exposure. At 3 days after treatment, the efficacy of K9 Advantix within 3 hours of natural tick exposure was 88.0% and declined slowly during the study. The 48-hour postexposure efficacy remained above 93.5% throughout the study.
