Performance of Termidor® HE High-Efficiency Termiticide Co-pack with Termidor® HE Technology Against Eastern Subterranean Termites Reticulitermes flavipes and Formosan Subterranean Termite Coptotermes formosanus in Laboratory Trials and Field Applications

Chris Keefer


Two laboratory and one field study were performed utilizing fipronil (C12H4Cll2F6N4OS), in the form of Termidor® HE Co-pack with Termidor® HE Technology. Laboratory studies included glass tube bioassays and collateral transfer effect trials. Glass tube bioassay results indicated that this formulation of Termidor® HE Co-pack was efficacious against Reticulitermes flavipes and Coptotermes formosanus caused 100% mortality of both species by 72 h post-exposure. Collateral transfer effect trials also showed efficacy of Termidor® HE Co-Pack with Termidor® HE Technology against both R. flavipes and C. formosanus by causing 100% mortality by 96 h. Termidor® HE Co-pack with Termidor® HE Technology was also applied to structures as a post-construction treatment for remediation of subterranean termite infestations. In field trials, 12 termite structures were treated with Termidor® HE Co-pack with Termidor® HE Technology (hereafter referred to as Termidor ® HE) and no subterranean termites were detected through 36 months post-treatment.
