FIDO'S Fre-Itch Rinse Concentrate is a pyrethrin-based flea, lice, and tick treatment for dogs and cats, including coverage against paralysis ticks. It's a rinse-format concentrate applied after shampooing.

The active ingredient is pyrethrin, a pesticide derived from natural plant sources. When diluted, the solution is poured or sprayed directly onto the coat — or used in a hydrobath for flea treatment. It also controls lice on ornamental cage birds and rodents when used as directed. The 500ml concentrate is designed to cover multiple treatments.

Suited to households that prefer a wash-on treatment over spot-ons or chewables, particularly those using a hydrobath setup. Works across species, which makes it practical for multi-pet homes.
