Stephen M. Vantassel, host of the Wildlife Control Consultant podcast, summarizes the research by Mr. King in his 2025 Pest magazine article. Mr. King performed field testing on vitamin D3 bait Selontra by BASF and explained what happens to the bait over 16 weeks. Mr. King then discusses how frequently pest control applicators should change the bait to ensure rodent consumption.
