Commercially, malathion is often applied to crops to combat the many sucking and chewing insects that may harm them, and is often utilized for the same purpose in home gardens. The organophosphate is frequently used in large efforts at mosquito control for public health as well, and in smaller quantities for the control of fleas, lice, cockroaches, and similar household pests. Application of the insecticide may be carried through a variety of means, such as a duster, fogger, spray can, shovel, or spreader, depending on the size and nature of the job.
