A formulation for controlling a lice infestation comprises a spinosyn or a physiologically acceptable derivative or salt thereof and a physiologically acceptable carrier. A spinosyn is a macrolide produced by the cultivation of Saccharopolyspora spinosa. Each spinosyn has a 12-membered macrocyclic ring that is part of an unusual tetracyclic ring system to which two different sugars are attached, the amino-sugar forosamine and the neutral sugar 2N,3N,4N-tri-O-methylrhamnose. The term "spinosyn or a physiologically acceptable derivative thereof" refers to an individual spinosyn factor (A, B, C, D, E, F, G, H, J, K, L, M, N, O, P, Q, R, S, T, U, V, W or Y), an N-demethyl derivative of an individual spinosyn factor, or a combination thereof.
