The resistance of synanthropic rodents to anticoagulant rodenticides is an emerging problem whose spread is constantly increasing. This is at the background of the growing interest towards the implementation of various non-anticoagulant rodenticides in deratisation practice, including cellulosebased baits. The aim of this study was to evaluate the efficacy of the cellulose-based rodenticide Eradirat (Republic Mills, USA) for control of warfarin-resistant black rats (Rattus rattus).The palatability and efficacy of cellulose-based rodenticide Eradirat were evaluated in field tests and a series of lethal feeding tests with (choice test) and without choice (no-choice test) on wild warfarin-resistant black rats (Rattus rattus). The palatability of Eradirat baits for studied black rats was extremely low, which resulted in zero efficacy of choice tests and field deratisation procedures. The 14-day nochoice feeding test with Eradirat, supplemented with additional attractants resulted in high efficacy (90%) in warfarin-resistant black rats. The results suggested a high deratisation potential of cellulosebased rodenticide Eradirat, but at the same time, outlined its low palatability for black rats as a very serious disadvantage thus making it inappropriate for use in practice. |
