Table 3 Estimated median (and 90% credible intervals) number of detection devices and device density needed to achieve a 95% probability of declaring ship rat (Rattus rattus) eradication (given no rat detections) for various combinations of Prior and deployment time, for two monitoring devices (chew cards and WaxTags).
From: Detection parameters for managing invasive rats in urban environments
