Seresto Collars are designed to stay effective for eight months. This is due to the slow release of ingredients from the collar itself. In order to get maximum protection from your Seresto collar, it should be worn at all times and replaced with a new one every eight months or sooner if necessary.
The active ingredients in Seresto collars provide long-lasting protection against parasitic insects such as fleas, ticks and lice. The presence of these active ingredients on a pets skin repels these parasites, thus preventing any chance of infection or infestation. The molecules in the insecticides also react with other elements in the surroundings that act as an irritant for ticks, fleas and lice, providing an overall layered defense that can last up to eight months when the collar is kept secure on the pet’s neck.
Pet Size: Larger pets may need more frequent applications
Pet size matters when it comes to Seresto collars. Generally speaking, larger pets such as German Shepherds, Great Danes, Labrador Retrievers and more, may need more frequent applications of Seresto collars than smaller pets. This is because larger pets may have higher levels of activity and heavy fur coats which can work against the effectiveness of the collar.
So if you have a large pet who seems to be wearing down their Seresto collar faster than other pets in your household, you may want to consider reapplying the Seresto collar more frequently. The manufacturer recommends changing them every 8 months for optimal effectiveness. However, if your large pet is active or seresto pet collar has thick fur that might interfere with the effectiveness of the collar ,you may want to switch collars out every 5 or 6 months instead.
Breed & Fur Density: Dogs with denser fur may need more frequent applications
For dogs with denser fur, the Seresto collar should be applied more frequently to ensure maximum effectiveness. This is because thicker fur can block the ingredients in the collar from coming into contact with your dog's skin. As such, be sure to read all the instructions on your particular Seresto brand package and reapply every 8 months if needed.
Even though each breed of dog has different fur types and thicknesses, you may want to test out the Seresto collar for at least a few weeks or a month before deciding how often you need to apply it for your pet. If fleas and ticks seem to persistently return even after re-application, you may need to increase the frequency of when you reapply the collar.
Environment: If your pet spends a lot of time outdoors, they may need more frequent applications
When it comes to how long a Seresto collar will last, it can depend greatly on your pet's environment. If your pet spends a lot of time outdoors, they may need more frequent applications due to environmental factors such as rainfall, mud and dirt that can reduce the effectiveness of the formula.
If you're noticing that your pet is getting fleas or ticks in spite of having a Seresto collar on, then increasing the frequency of application might help. Additionally, you should also look into removing potential sources of infestations such as flea beds or other animals carrying parasites entering your pet's yard.
For pets spending a significant amount of outdoor time, checking and re-applying their Seresto collar every 6 months is recommended to ensure the most effective protection from fleas and ticks.
Activity Level: More active pets may require more frequent applications
It's important to take your pet's activity levels into consideration when deciding how long to keep a Seresto collar on them. Generally, most Seresto collars last 8 months, but more active pets might need theirs replaced more often.
The reason for this is that the active pet’s fur and skin will rub against the collar more in comparison to an inactive pet. This can cause some of the chemicals within the collar to become worn off or less effective over time leading to flea protection becoming compromised.
If your pet is very active, it’s best to replace the Seresto collar every 6 months in order to maintain peak performance of the product and not compromise their protection from invading pests. The same goes for pets concerned about ticks, as having a greater effectiveness of the product guarantees better tick prevention during tick season and any other season for that matter!
All in all
While Seresto collars offer long-lasting protection against fleas and ticks, there are a variety of factors that determine how long they will last.
