The RAT Problem

UHills Rodent Management History

ICHA had already ceased use of anticoagulants when HOOT was formed. In 2019 rodent management was accomplished with the rodenticide Selontra with the active ingredient cholecalciferol in rat bait stations serviced monthly by a pest management company.

Compared to anticoagulants, cholecalciferol had been touted as a lesser threat to pets and wildlife, however there was some evidence that secondary poisoning could occur. HOOT proposed that ICHA switch to enclosed snap traps to eliminate the possibility of poisoning pets and raptors.

In 2025, ICHA began a trial of a non-hormone rat control product called Evolve by SenesTech. This “birth control” bait in conjunction with snap traps is being evaluated for efficacy and cost.
