About ADAMS
ADAMS has made flea and tick products since 1975, when its line was sold exclusively through veterinary clinics before moving onto retail and online shelves. The brand is now a division of Central Garden & Pet Company, a publicly traded manufacturer of branded pet and garden products, and in 2026 ADAMS marked its 50th year with the launch of a plant-based, EPA-approved flea and tick spray for pets and homes.
Rather than a single spot-on, ADAMS sells a full system meant to be used together: pet-facing shampoos, sprays, spot-ons, and collars alongside home foggers and carpet sprays and a hose-end yard spray, on the premise that fleas hiding in carpet and yard need treating alongside the pet itself. Its Plus Flea & Tick Shampoo with Precor pairs an on-contact kill of fleas, flea eggs, ticks, and lice with Precor, an insect growth regulator that keeps stopping new eggs from hatching for up to 28 days after the bath -- a combination built for resetting an active infestation rather than long-term prevention alone.

Why we recognized ADAMS
The House of Mittens Top Brand recognition isn't paid for and can't be applied for. We award it to the brands whose products consistently stand out in our vet-reviewed category guides. ADAMS earned it on the strength of the products below, evaluated the same way every product on this site is: assessed against feline-health criteria, used with real cats, and judged on merit.

Kills fleas, flea eggs, ticks, and lice on contact during the bath, giving a heavily infested cat an immediate reset, and its Precor insect growth regulator keeps stopping new eggs from hatching for up to 28 days afterward.
