How long will an unopened Seresto collar last

The Seresto Flea & Tick Collar is designed to provide continuous protection for 8 months when worn on your pet. This means that if the collar is not opened, it will remain effective for up to 8 months. The active ingredients in the collar slowly release over an 8-month period, providing complete protection against fleas and ticks throughout the entire time. Additionally, the unopened collar protects your pet even against re-infestation; meaning if any new fleas or ticks enter their coat and attempt to bite, they will be killed by the active ingredients found in the Seresto Collar.

What is the Expiration Date for an Unopened Seresto Collar?

The expiration date of an unopened Seresto collar varies depending on the type. For example, a flea and tick prevention-only collar typically has a three year expiration date, while a flea and tick plus heartworm prevention-only collar may have an expiration date of up to five years.

It is important to check the packaging for the specific expiration dates after purchase. Preferably, you should purchase collars with as much time left on their expiration dates as possible in order to get the maximum time out of them.

If you have any doubts or questions about when your Seresto collar’s expiration date is, contact your veterinarian for confirmation – they will be able to provide the most accurate and updated information about the product you purchased.

How Should You Store Your Unopened Collar?

The key to a long lasting Seresto collar is proper storage. Unfortunately, in most cases, it’s not as simple as just sticking it on the shelf until you need it. Unopened collars should be stored in a cool, dry place away from direct sunlight and extreme temperatures. Additionally, they should not be exposed to dust or moisture so make sure that you store them in a clean, air-tight container where they won’t be bumped around or subjected to outside influences.

Generally speaking, keeping an unopened Seresto collar at room temperature will ensure that it lasts up to 2 years. If stored are seresto flea collars safe for dogs correctly under the right conditions, however, your collar can last even longer! So make sure to follow the guidelines mentioned above and your collar will stay fresh and effective for many years to come.

Can You Still Use an Expired Unopened Collar?

No – it is not recommended to use an expired unopened Seresto collar. The efficacy of the product diminishes over time, so it is best to purchase a new Seresto collar as soon as yours expires. Although the active ingredients in the collar may still be effective, there’s no telling how their potency has changed over time and can be unpredictable. Additionally, many of the ingredients that make up the active components in a Seresto collar are volatile and will evaporate with age, meaning they will eventually become less effective.

It is also important to note that using an expired unopened Seresto collar could pose a potential health risk for your pet. Since there’s no way to know for sure whether or not the key active ingredients are still present at their original levels of potency, it’s always best to err on the side of caution and buy a new collar.

In consolidation

Unopened Seresto collars can be stored for three years from the manufacture date, though usage past this may depend on environmental factors or degradation resulting from improper storage. It’s best to always consult with a veterinarian when considering using an expired product.
