No, you do not need to activate Seresto flea collars when you purchase them. They are ready to be used as a preventative flea and tick treatment for your furry friend and provide eight months of lasting protection. The collar only needs to be secured snugly around your pet’s neck and the active ingredients will get released from the collar gradually over time. You can also use it along with other flea treatments, such as spot-on treatments or shampoos, to maximize its effectiveness. The collar is waterproof so you don’t have to worry about taking it off before going outside or swimming in water. It’s also adjustable so that you can adjust the fit on any size pet they have.

Take off the Safety Tab

Before using your Seresto flea collar, you must first activate it by taking off the safety tab. This tab is located at the end of the collar and prevents it from releasing the active ingredients until you are ready to use it.

Once you’ve taken off the safety tab, you can slide the plastic buckle up so that it sits close to your pet’s neck — this is important for delivering proper protection from fleas, ticks, and other parasites.

When the collar is in place, make sure that there is enough space for one or two fingers to fit between your pet’s neck and the collar for a comfortable fit. If necessary, adjust accordingly as needed.

Finally, don’t forget to discard the safety tab in an appropriate location; never discard these tabs near children or animals as they can be hazardous if ingested! Now you’re all set – enjoy having peace of mind from knowing that your pet has superior flea protection with Seresto!

Apply the Collar Firmly on Your Pet’s Neck

In order to activate your Seresto flea collar, it must be applied correctly. You should apply the collar firmly on the pet’s neck and make sure that it is snug but not too tight. You may need to readjust the fit after a few hours or days as your pet’s fur and body shape can change over time.

When you apply the collar, leave 2-3 inches between the material against your pet’s fur and their skin to ensure that they don’t feel uncomfortable. Keep checking periodically to make sure it is not too loose or tight, as well as verifying that the buckle of the collar is secured tightly and isn’t sliding around on your pet’s neck. This will ensure that your Seresto flea collar works effectively and your pet remains safe from fleas and other pests for up to 8 months!

Activate the Anti-Tick Protection

To activate the anti-tick protection of your Seresto flea collar, all you have to do is open the package and fasten it on your pet’s neck. Once in place, the unique formula will activate a protection that is effective for up to 8 months!

The active ingredients for Seresto will start killing adult fleas immediately and prevent new infestations within 24 hours. It even kills ticks for extended periods, up to 8 continuous months. This includes killing brown dog ticks, American dog ticks, lone star ticks, and deer ticks – all of which can transmit Lyme disease or other serious illnesses.

So now that you understand how Seresto works, let’s discuss how to get the most out of its protections by properly activating it when you first place it on your pet. Make sure you unroll the collar evenly and leave enough slack so that your pet can move comfortably with plenty of room to breathe. Tightening the collar too much can cause discomfort or even restrict blood flow in extreme cases.

On a final note

It is important to activate your Seresto flea collar correctly so that it effectively protects your pet from fleas and ticks. Activation is easy and quick and can be done in just a few steps.
