Good Questions

The new Flea & Tick Shampoo is more effective than ever, now killing fleas and flea eggs found on your pet, when used as directed. We added Vitamin E and glycerin for skin and coat health, plus a plant-derived surfactant for a richer lather and easier rinse.

Beyond the formula, the bottle has been upgraded for easier use and a premium look, and every batch is now crafted with care in our Austin, Texas facility. You’ll also find three new scents—Cedarwood, Lemongrass, and Rosemary—joining Peppermint for a fresh, cohesive experience.

Yes! Flea & Tick Shampoo can be used alongside Flea & Tick Pets + Home, as well as Wondercide Spot On or Collar.

The Spot On and Collar are water resistant but not waterproof. When using the Spot On, schedule your applications between bathing. For the Collar, remove it before bathing and then put it back on afterward. Do not use Spot On and Collar together - choose one or the other.

Spray your pet with Flea & Tick Pets + Home once dry. It can be used as often as needed, depending on pest pressure.

Flea & Tick liquid shampoo is designed to be used once weekly as needed. If your pet is experiencing a more persistent flea issue and you notice a few remaining after the first bath, you can repeat the application in 2–4 hours, not more than twice in 24 hours.
