Selontra is based on the non-anticoagulant rodenticide cholecalciferol, at 0.075%, presented as a highly palatable soft block formulation. Cholecalciferol is effective against anticoagulant-resistant rats and house mice. 

It is not bio accumulative or persistent and therefore presents relatively lower secondary poisoning risks to non-target species, such as birds of prey, compared to second generation anticoagulants. Areas and types of use are indoors and outdoors around buildings, permanent baiting, tamper-resistant bait stations and in covered and protected baiting points.

Active substance: 0.75 g/kg (0.075% w/w) cholecalciferol 750 ppm
