Working with Vectorcide, The Butterfly Tree Charity, with the use of Vectorcide products has considerably reduced the number of known malaria cases by 83.0%  in an initially treated region on a year-on-year time horizon. Since then, many Vectorcide-treated areas are now experiencing NO new cases of malaria, said Jane Kaye-Bailey of The Butterfly Tree Charity

VC Coating and Granules were applied in the Mukuni  Chiefdom. A total of 740 structures were painted with the VC  coating and the Mukuni Chiefdom recorded only 200 new cases of Malaria in the treated district. In the nearby similar Ndola Chiefdom which chose NOT to have VC products, a staggering 4,516 new cases of malaria were recorded.

In Moomba Chiefdom, 46% of the population had malaria in 2017. In December that year, the charity started a programme to provide universal Vectorcide coverage for the entire Chiefdom.
