ZeroVector® Durable Lining - Evidence of Impact

  • Rate of loss of deltamethrin slows over time leading to the conclusion that the reservoir is sufficient for five years
  • 100% mortality of mosquitoes after more than two years of field use exceeds international standards for IRS (which stipulate 80% mortality after 30 minutes exposure in cone test)
  • Trial continues into 2010 (four years after installation)

Even in as short time as six months, Durable Lining already begins to outperform in some bioefficacy trials.

[Mali, 2009]

Graph of impact of roof type of ZeroVector Durable Lining

  • Bioassay using lab-reared Anopheles sp.
  • 2 cones/ wall, 10 min exposure, 24 hour mortality

Malaria Research & Training Center, Mali

  • Village of N’galamadibi 130 km NE from Bamako
  • Installations August, 2008 (green shade cloth)
  • Roof type had no effect on DL efficacy

Although no data were collected, it appears DL dramatically reduced termite activity
