HONOLULU — SenesTech, a developer of proprietary technologies for managing animal pest populations through fertility control, announced that the first phase of data has been presented on the use of ContraPest for the control of rats in an outdoor setting, specifically the control of wild rats that prey upon native birds and plants in a native forest.

Tyler Bogardus, principal investigator from the O’ahu Army Natural Resource Program (OANRP), presented phase one data at the 25th annual Hawai’i Conservation Conference, hosted by the Pacific International Center for High Technology Research. The data came from a year-long trial assessing the effectiveness of ContraPest in the Waianae Mountains in O’ahu. The goal of the study, under the EUP, was to determine whether ContraPest could be deployed effectively and safely to reduce populations of Rattus species in a forest setting.

Senestech reported that data for the first phase of this ongoing study presented the following observations:

  • Palatability: ContraPest's sweet taste and fatty content drove growing consumption throughout the trial, even while popular competitive food sources such as strawberry guava were in season.
  • Stability: ContraPest did not attract insects or slugs under the challenging conditions of the study.
  • Non-Targets: No adverse reactions to other wildlife or plants were observed.

"This has been the first demonstration of ContraPest use in a full outdoor environment. Based on the preliminary results of this study, we will now, with confidence, pursue full outdoor use label requirements for ContraPest in an effort to provide a viable solution to address the rodent devastation to our island communities,” said Dr. Loretta P. Mayer, chair, CEO and co-founder of SenesTech.

The study is being conducted by the Pacific International Center for High Technology Research in support of the U.S. Army's Natural Resource Program on O'ahu and its endangered species protection efforts. Final data collection is underway for this and next month.
