title: Larvicidal effects of boric acid and disodium octaborate tetrahydrate to cat fleas (Siphonaptera: Pulicidae).
abstract: Borate products varied in efficacy against larval cat fleas, Ctenocephalides felis felis Bouché, with some effective at rates of 23 micrograms/cm2 when larvae were exposed to the compounds in sand. Powdered boric acid, granular boric acid, and disodium octaborate tetrahydrate (Polybor) at rates of 200 micrograms/cm2 produced < or = 90% mortality of larvae exposed in carpet for 96 h. LC50 values of larvae exposed in treated carpets for 96 h were 23 micrograms/cm2 for powdered boric acid, 40 micrograms/cm2 for granular boric acid, and 47 micrograms/cm2 for polybor.
