Low-dose cholecalciferol bait for possum and rodent control

Cholecalciferol: a Unique Toxicant for Rodent Control

Cholecalciferol is an acute (single-feeding) and/or chronic (multiple-feeding) rodenticide toxicant with unique activity for controlling commensal rodents including anticoagulant-resistant rats. Cholecalciferol differs from conventional acute rodenticides in that no bait shyness is associated with consumption and time to death is delayed, with first dead rodents appearing 3-4 days after treatment.

Bait-Station Spacing for Possum Control in Forest

Science for Conservation presents the results of investigations contracted to science providers outside the Department of Conservation. Reports are subject to peer review within the Department and, in some instances, to a review from outside both the Department and the science providers.

Criteria for Rodent Bait Selection

World food shortages become more acute each year, and all too often, rodents are present to take their unwarranted share. To counter this, we must refine our rodent control methods to make them more efficient. To this end, correct bait selection is essential. Grain baits must be selected for purity and acceptability. Grain alterations must be carefully controlled, as well as any additives. Mult...

Combining Aspirin with Cholecalciferol (Vitamin D3) – A Potential New Tool for Controlling Possum Populations

The introduced Australian brushtail possum is a major vertebrate pest in New Zealand, with impacts on conservation and agriculture being managed largely through poisoning operations. Cholecalciferol (vitamin D3) is registered for use in controlling possums and despite its many advantages it is expensive and relatively inhumane. Combination of a high proportion of aspirin with a low proportion o...
