Our verdict
Adams Plus Flea and Tick Shampoo combines active ingredients aimed at adult fleas, flea eggs, ticks, and lice with a coat-conditioning wash, and with nearly 33,000 reviews at a 4.4 star average, it's one of the most established flea shampoos on the market.
Owners dealing with an active flea, tick, or lice infestation who want a treatment shampoo rather than a purely cosmetic wash, suitable for dogs, cats, puppies, and kittens over 12 weeks.
Skip if
Your pet has sensitive skin or you're only looking for routine cleaning, since this is a treatment-focused formula built around active pest-control ingredients rather than a gentle everyday shampoo.

Performance notes
The formula combines pyrethrins, piperonyl butoxide, and pyriproxyfen as active ingredients, targeting adult fleas and ticks as well as flea eggs through the Precor growth regulator component, which helps break the flea life cycle rather than just killing adult pests. Since it's also designed to clean and condition, it functions as a combined treatment-and-bath product rather than requiring a separate regular shampoo.
What buyers say
With 32,921 reviews and a 4.4 star average, plus roughly 10,000 units bought in the past month, this is one of the most reviewed and consistently purchased flea and tick shampoos available, reflecting a long track record of buyer trust.
Yes, the product is labeled for use on dogs, cats, puppies, and kittens over 12 weeks of age.
Does this shampoo kill flea eggs, not just adult fleas?
Yes, the formula includes Precor along with pyrethrins and piperonyl butoxide, and the label states it kills adult fleas, flea eggs, ticks, and lice.
Can this shampoo also be used as a regular cleaning shampoo?
Yes, it's marketed to clean and condition the coat as part of the same wash used for flea and tick treatment, so a separate everyday shampoo isn't strictly necessary when using it.
