This paper is in continuation to a series of articles published on the work being developed in Brazil regarding the feasibility of using photostabl synthetic pyrethroids against termites. Tests were carried out to compare the efficacy of five synthetic pyrethroids with the traditional organo-chlorinated pesticide, chlordane. Wooden blocks were impregnated with alcohol-based solutions of the above-mentioned products at four different concentrations, and 13 years later these blocks were exposed to dry-wood termites. Results of these tests showed that Deltamethrin, Cypermethrin and Fenvalerate were still effective after this period of time.
