How Long Do Seresto Collars Last?
Seresto collars are designed to provide continuous flea and tick protection for dogs for 8 months.
This is the maximum duration of effectiveness you can expect when the collar is used properly according to the instructions.
The active ingredients in a Seresto collar are gradually released from the polymer matrix in the collar and spread over your dog’s coat.
It takes about 48 hours after first putting the collar on for the active ingredients to build up to optimal levels in your dog’s hair and skin surface.
Once at full strength, the insecticide ingredients work together to repel and kill fleas and ticks. The Seresto collar provides:
- 8 months of flea protection: Kills and repels fleas before they can bite.
- 8 months of tick protection: Repels and kills ticks, including those that may transmit Lyme disease and other tick-borne diseases.
So in general, a Seresto collar should safely protect your dog from fleas and ticks for a full 8 months when used properly. This long-lasting protection means you only need to replace the collar a few times per year instead of applying monthly treatments.
When to Replace the Seresto Collar
To maintain continuous flea and tick protection, it’s recommended to replace the Seresto collar every 8 months.Here are some key tips on when it’s time to swap out your dog’s Seresto collar:
- Replace every 8 months – For most dogs, replace the collar every 8 months to maintain full flea/tick protection. Mark your calendar to remember when it’s due.
- Replace after 5 months for dogs who swim or bathe frequently – Dogs who swim or are bathed more than once per month may need more frequent collar replacement, as water can wash away active ingredients. For these dogs, replace the collar every 5 months.
- Replace immediately if the collar is damaged – Check the collar regularly for any damage or breaks. If the collar becomes cracked, cut, or broken, replace it right away to ensure continued protection.
- Watch for signs of reduced efficacy – Look for fleas/ticks on your dog, skin irritation, or other evidence the collar may no longer be working. Consult your vet if you notice any loss of effectiveness before 8 months.
- Don’t exceed 8 months of wear – For safety, always replace the collar within 8 months of application, even if it appears intact. The ingredients may be depleted.
Following these guidelines will help ensure your dog gets the full 8 months of flea and tick protection from each Seresto collar. Swapping out the collars on schedule is key to keeping your pup pest-free.
