Household insecticide used for malaria

Malathion Malathion has the least toxicity of all organophosphorous compounds. The technical product is a yellow or clear- brown liquid with an unpleasant smell. Commercially, water- dispersible powders are available. Malathion is used in doses of 100-200 mg. per sq. ft., every 3 months. Because of its low toxicity, malathion has been recommended as an alternative insecticide to DDT. As a low volume (ULV) spray, malathion has been widely used for killing adult mosquitoes to prevent or interrupt dengue-haemorrhagic fever, and mosquito-borne encephalitis epidemics Ref:Park's TextbooK Of Preventive and Social Medicine 25th Ed Pgno: 820
