Rattus spp

Rodents remain one of the most widespread and damaging invasive alien species on islands globally. The current toolbox for insular rodent eradications is reliant on the application of sufficient anticoagulant toxicant into every potential rodent territory across an island. Despite significant advances in the use of these toxicants over recent decades, numerous situations remain where eradication is challenging or not yet feasible.

Rattus rattus, or black rats, are rampaging through Tuvalu's atolls and gnawing through the country's chief export crop - coconuts.
