How fast can Seresto Flea Dog Collars kill fleas?
The Seresto flea and tick collar for dogs starts working quickly once its activated on your dog.
In the first 24 hours, the Seresto collar will have killed all the living fleas that are on your dog.
Those live fleas are the ones that are causing distress to your dog with itching and the resulting skin irritation and in many dogs, flea allergy dermatitis.
Once the live fleas are dead, any eggs will be hatching and those new live fleas will be killed within two hours. This means the fleas have very little time to cause any significant itching to your dog.
While the Seresto flea collar is doing its job, your dog’s environment and bedding should be thoroughly cleaned, vacuumed and/or replaced to remove all flea eggs and flea larvae.
Seresto’s flea and tick collar kills off fleas that are directly on your dog and it does this quickly and competently for most dogs.
That’s one half of your flea eliminationg strategy. Keeping on top of the environment, especailly places that can harbor fleas and their eggs, such as in bedding, dog clothes, and dog houses is critical if you are to stop the cycle of live fleas.
