When is frontline waterproof

Doses are effective for one month, but the manufacturer recommends more frequent administration during tick season. Avoid bathing your dog immediately after applying Frontline in either spray or topical form.

Frontline products contains fipronil, the active ingredient that kills adult fleas infesting a dog. Fipronil works its way into the hair follicles, where it remains trapped by the sebaceous or oil glands, making it resistant to being washed away with bathing.

The oil produced by the sebaceous glands also distributes the fipronil. Fleas need only to come into contact with the fipronil for it to be effective; they do not need to ingest it through a bite. This hyperstimulation kills the fleas. Frontline Plus's second active ingredient, S -methoprene, is an insect growth regulator that kills flea eggs and larvae.

Frontline Plus is safe for puppies over eight weeks. View Advantage II on Amazon. Advantage II, a topical product by Bayer, claims to kill fleas within 12 hours.

It treats fleas in all stages adults, eggs, and larvae , as well as flea allergy dermatitis and lice. Unlike Frontline, it does not kill ticks. The two main ingredients are:. Both ingredients work together to break the flea cycle. Advantage II is also waterproof and lasts up to 30 days. The product never expires so long as you store it to package specifications and is safe for puppies seven weeks and older.

Both Frontline Plus and Advantage II are available in topical form and should be applied using the following steps:. Frontline Plus is slightly less expensive than Advantage II and protects both against fleas in their various stages and ticks whereas Advantage only treats fleas and is more costly. Advantage II clearly states that it kills fleas within 12 hours on its packaging, while Frontline Plus does not, but their website claims it terminates them in 24 hours.

While both products are similar in application and shelf life, Frontline Plus has the added value of killing both ticks and fleas. However, if you need more immediate results, you might be better off paying a little more for Advantage II. Keep in mind that a product that works for one dog may not work as well for another.
