Treatment and prevention of flea and tick.
General Information
EPA approved for use in dogs. Available over the counter. Permethrin is a manmade form of the naturally occurring pyrethrin. (Permethrins should NOT be used on cats.) Both interfere with the nervous system of the flea or tick paralyzing and killing it. May take 3-7 days for highest effect.
The topical spot-ons spread over the body with the body oils and collect in the hair follicles, and then are released over time (up to 1 month) from the hair follicles onto the skin and hair. Repeated bathing or swimming may decrease efficacy and require reapplication earlier than the normal 4-week intervals. Special shampoos, such as Bio Guard, can be used which do not remove the topical spot-on products. Bio Spot for Dogs also contains an insect growth regulator to help kill the immature fleas.
