COMPOSITION  10g/L Pyrethrins, 18g/L Piperonyl butoxide, 30g/L N-Octyl    Description  A low odour, water based formulation suitable for use in a hydrobath, rinse, dip or spray. Contains no alcohol or petroleum solvents.    Action  The natural pyrethrins, which have no anticholinesterase activity, act in insects by slowly closing the sodium channel activation gate causing hyperexcitation followed by convulsion and death. They are synergised by Piperonyl butoxide, which has a minor repellant action in its own right. N-Octyl bicycloheptene dicarboximide (MGK 264) is an insecticide synergist and it has repellant properties.    Indications  Fleas (Ctenocephalides spp) and lice (Trichodectes canis and Heterodoxus spp), ticks including the paralysis tick (Rhipicephalus sanguineus and Ixodes holocyclus) and prevents attachment for up to 3 days on dogs and cats. Controls lice on ornamental cage birds.
