Before DDT, eliminating mosquito breeding grounds by drainage or poisoning with Paris green or pyrethrum was sometimes successful. In parts of the world with rising living standards, the elimination of malaria was often a collateral benefit of the introduction of window screens and improved sanitation. [ 44 ]
Although RID once contained DDT as an active ingredient, it has since been removed when the effects of this highly toxic substance became more known worldwide. According to the American Mosquito Control Association's Web site, DEET remains the standard by which all other repellents are judged.

Mosquito-control operations are targeted to multiple problems: Nuisance mosquitoes bother people around homes or in parks and recreational areas;
Deltamethrin is a pyrethroid composed of a single stereoisomer, of a possible 8 stereoisomers, selectively prepared by the esterification of (1R,3R)- or cis-2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropanecarboxylic acid with (alpha,S)- or (+)-alpha-cyano-3-phenoxybenzyl alcohol or by selective recrystallization of the racemic esters obtained by esterification of the (1R,3R)- or cis-acid with the ...
The screw-worm fly was the first pest successfully eliminated from an area through the sterile insect technique, by the use of an integrated area-wide approach..
