10 Best Flea Shampoos 2025 in the United States

Adams Plus Flea & Tick Shampoo with Precor is formulated for cats, kittens, dogs, and puppies over 12 weeks of age, making it suitable for a wide range of pets. One of its main strengths is the ability to kill adult fleas, flea eggs, ticks, and lice, providing comprehensive pest control. The presence of Precor, an Insect Growth Regulator, helps prevent flea reinfestation by inhibiting the hatching of flea eggs for up to 28 days.

This shampoo is also designed for pets with sensitive skin, incorporating soothing ingredients like aloe vera, lanolin, coconut extract, and oatmeal, which can be beneficial for maintaining your pet's skin health. Additionally, it conditions the coat, leaving it soft and shiny with a pleasant, light fragrance. However, it requires careful application and rinsing, and can't be used on pets younger than 12 weeks.

While it is effective, users need to repeat the application every 7 to 10 days for adult flea relief, which might be cumbersome for some. The relatively small amount needed per use makes it economical, but the frequency of use could offset this. It is a reliable option for those seeking thorough flea and tick control while also catering to sensitive skin needs.

Adams Plus Flea & Tick Shampoo with Precor is a versatile flea treatment suitable for both cats and dogs over 12 weeks old. One of its main strengths is its effectiveness in killing not only adult fleas but also flea eggs, ticks, and lice, which helps prevent reinfestation. The inclusion of Precor, an Insect Growth Regulator, ensures that flea eggs are managed for up to 28 days, offering long-lasting protection.

Another notable feature is its sensitive skin formula, which includes soothing ingredients like aloe vera, lanolin, coconut extract, and oatmeal, making it ideal for pets with delicate skin. The shampoo also conditions the coat, leaving it soft, shiny, and manageable, and has a lightly scented fragrance that keeps pets smelling fresh. Users have found that a little product goes a long way, which adds to its value for money.

However, there are a few considerations to keep in mind. This shampoo is not suitable for pets younger than 12 weeks, and it requires a thorough application and rinsing process that might be time-consuming. Additionally, while it offers a pleasant fragrance, some pets or owners with sensitivities to scents might find it noticeable. In conclusion, Adams Plus Flea & Tick Shampoo with Precor is a strong choice for pet owners seeking an effective and gentle flea treatment for both cats and dogs, provided their pets meet the age requirement.
