Wiki section on DDT

DDT - Wikipedia, the free encyclopedia: "As of 2005, DDT continues to be used in other (primarily tropical) countries where mosquito-borne malaria and typhus are greater health problems than DDT's potential toxicity. Use of DDT in public health to control mosquitoes is primarily done inside buildings and through inclusion in household products and selective spraying; this greatly reduces environmental impact compared to the earlier widespread use of DDT in agriculture. It also reduces the risk of resistance to DDT."
