The amount of DDT used was 15.785 kg in 2001, 14.508 kg in 2002 and 6.483 kg in 2003.¹

The amount of DDT used was 71.480 kg in 2003, 82.816 kg in 2004 and 87.433 kg in 2005.¹

Reported DDT use in:
2003: 53.610 kg a.i.;
2004: 62.112 kg a.i.;
2005: 65.575 kg a.i. ^6.3

In 1995/1996 144.000 kg of DDT was used for IRS. In 2000 7.000 kg was used.⁵

DDT is used for disease vector control in accordance with WHO Recommendations and requirements of the Stockholm Convention.²

The use of DDT had been phased out at the beginning of 1999 and replaced with pyrethroids. However, DDT was reintroduced due to resistance of mosquitoes to pyrethroids.³

In 1997, DDT was replaced with deltamethrin and cyfluthrin but mosquito resistance to these prompted limited reintroduction of DDT in 2000.⁵

The major malaria vector control strategy in South Africa is IRS using DDT (50%) and pyrethroids (50%). This consumes approximately 100 t of DDT annually.⁵

A winter larviciding programme using Vectobac (Bti) was used and reduced the mosquito breeding during winter months, offering positive benefits during the summer months in minimizing vector densities.⁵
