The Seresto Flea and Tick Collar is the most convenient and cost-effective form of long-term parasite prevention available, providing 8 continuous months of protection from a single collar — eliminating the monthly application routine required by topical treatments. The active ingredients Imidacloprid and Flumethrin are released continuously at low concentrations from the collar polymer, distributing through the skin oils to provide systemic coverage. Kills fleas within 24 hours of contact, kills ticks within 48 hours, and repels them before they attach. Water-resistant construction maintains effectiveness through swimming and bathing. At approximately $7.50 per month of protection, Seresto is typically more economical than monthly topical treatments. The safety release mechanism breaks the collar if it becomes snagged. Veterinarian recommended and available in sizes for small, medium, and large dogs. For dog owners who want reliable, hands-off parasite prevention, Seresto is the premier solution.
